I need to replace the ignition wires on my slick magneto. When I called Skytronics to get one they said they only did goverment work now. I initially had a custom harness made so I don't know if off the shelf wire lengths will be ok. Anybody know of a source  for harnesses? Or how to find out the lead lengths of standard harnesses?

I called that harness/mag seller...blanking on the name right now.  They were able to have a custom one made for me.  Both slick and Kelly I think will do it. Anyway, I was able to get one for the IO-390.

If you send your harness to Herber Aircraft in SoCal they can duplicate it for you.

I should mention that one option is a complete build it yourself harness.  There are some tools to buy but I think that will be the route I go next time.  With the proper tools it would be easy.

I have a set of stock Slick harnesses on the shelf, I can measure them for you if you still need the lengths.

Lenny: I have a Lightspeed electronic ignition on the right so I have only 1

Slick mag 6351) on the left. Plugs are large  barrells 3/4"). When I set

this up I  combined wires from a Skytronics set to get proper wire lengths

since some of the wires were too short. So I have 6 unused wires left over.

3 of them are too short to be of any use but the other 3 would work to start

a new harness. sing those wires as a start what I need at a minimum is 3

wires at least 60", 50" and 41" long. If someone has a harness that they

would be willing to sell I  am very  interested because every place I have

looked has 2-3 week lead times. So far haven't found any on the shelf at

local suppliers. Spruce list harnesses only by engine type/suffix so I don't

know how long the wires are.



Lenny, if you could measure your harnesses I would appreciate it. Do you

know what suffix they were made for? I have found it very easy to

move/replace wires around in the caps so that is not a problem. I wonder if

somebody just makes up wires to order. I'd just order what I need and

install them myself.

Before I start this emailYou builders may want to grab this

and save it as it was hard for me to find and obtain.



http://www.myrv10.com/files/engines/Slick_Mags/Slick_Mag_L-1499B.pdf

You can buy the Skytronics type individual repair leads

as a single lead from Spruce and other places. That would

probably be a good way to go. They come nice and long

so then you can just chop them to the best length for

your routing.   On my RV-10 I was able to use my

standard Left side harness. I wish I had the part number

but I don't have it handy.  But, that would rely on

routing the wires the same way I did. With so much

variation in the way people do things, I would think that

your best bet is just making it custom yourself.

That also helps get rid of long lead times waiting for

a specific harness. I found the same thing when I needed

my IO-390 Harness. I don't know what's going on in the

industry but people don't seem to be stocking things

very much.  My plan for harness replacement time is

to just buy the tools and build my own length replacement

leads as needed.



Oh, and I did work with a guy named Justin Phillips

at Quality Aircraft Accessories who was the person

who was able to get me a custom harness made.



Try him once.  His email is jphillips and it's at

the domain of qaa.com.  It was cheaper than buying

all 4 of the individual repair leads that I needed if

I wanted to do all 4 wires and make them look

identical.



I guess while I'm documenting it here, there was a guy

named Joe Logie at champion who also can get custom

slick stuff.  joelogie is his email and it's at

champaero dot com.



Slick also makes a repair lead, just like Kelly

(Skytronics) does.



There are 2 part numbers I have:



M7502-72 3/4 SLICK SINGLE LEAD KIT 72" RED 	08-13617 	$156.75



M7502-60 3/4 SLICK SINGLE LEAD KIT 	08-13619 	$149.75



Also, to repair leads, here are some part numbers:



SLICK M7503 3/4 20 HARDWARE KIT 	08-05870 	$38.50



SLICK K3300 INSL SLV&WSHR KIT 	08-01374 	$13.50



SLICK M1498 ELECTRODE SCREW 	08-02003 	$4.75



M2929 SPRING 	07-03363 	$3.35

Here is part number info on the Kelly lead:

Kelly repair lead



http://www.aircraftspruce.com/catalog/eppages/harness08-13222-5.php?clickkey=68292



KELLY S100-72 72" 3/4 LEAD ASSY STRAIGHT 	08-13224 	$84.75

And I have this note on the tools:



The Slick® Assembly Tool Kit is required to install all Slick Ignition 

Harness Leads on all magneto harness caps and spark plug termination ends.



The complete kit includes: Pressing Tool, #72 Drill Bit, Pin Vise, 

Stripping Tool, Spring Assembly Tool, and Shield Stripper.



Complete instructions for the use of this kit can be found in the Unison 

Industries L-1178 Service Manual.

They all have about 100 hours on them. You are welcome to borrow the left side Slick until you get yours sorted out. Looks like the lengths between the Slick and Skytronics are all over the place, some leads are longer some are shorter. When I ordered the Skytronics harnesses from QAA I just gave them the harness number off the Slicks, looks like they just eyeballed the lengths.

Thanks Tim. Since I had 3 unused but new leads long enough I bought 3 more

from Spruce plus the tool. Skygeek had it cheaper but Spruce3 matched the

price.

I made repairs to my Slick harness and have some things to share. I understand there are various mag models and this may not apply to them but mine is a 6351. The pdf document that Tim Olsen shared (Champion L-1499B Ignition Lead Assembly & Maintenance Manual) is what I referred to. I bought the T-200 Slick Ignition Harness Tool Kit from Spruce and three 72" lead assemblies (Kelley S100-72) . The maintenance manual is somewhat inadequate in that it referes to Slick Ignition wires that apparently differ from either Skytronics or Kelley. The Slick wires referred to in the maintenance manual have a coiled center conductor whereas Skytronics and Kelley have a stranded conductor. On Slick wire you have to insert the little screw (that holds the spring) into the coiled conductor but on stranded wire it is crimped on. I just happened to have a crimper that works which I got from SteirAir to crimp the pins for my intercom connectors.

 

Since the spark plug ends are already on the Kelley leads, cutting them to the right length, crimping the little screw on and then pressing them into the mag cap went well.Â  The Kelley 72" leads are somewhat expensive, for me about $85 each so to build a complete 6 or 12 wire harness would be out of the question. Better to buy one. My problem was I couldn't find out how long the leads were in any specific kit without pulling one off the shelf and measuring them plus I had 3 leads that were long enough so only needed 3. Also lead time to have a custom harness made were way too long.

 

I see big problems in trying to make your own harness: where to get lead wire and where to get the various parts at the mag end (drive ferrule, insulator sleeve, crimp on connector and spring). Plus you will have to make up the plug end also and get those parts.

 

Repairing mine using Kelleys leads worked OK for me but next time I'm going to look for someone else to make me a complete harness.

I'd agree with everything you said.

FIXING a harness would be affordable but these days the prices of harness components is just too high and so are the harnesses.  We're all screwed if we want it done cheap.  The cheapest option would be to find a harness that we can use 1/2 of.  Unfortunately it's almost impossible to buy a 1/2 harness now.  So you buy a complete system and only use 1/2.  If you're lucky and can use a stock part number then it's not totally unaffordable.

But finding a consistent proper length stock harness is tough as slick vs Kelly/skytronics don't seem to follow the same lengths.

Having a custom harness done is not that much more expensive if you go Kelly/Skytronics, but, the process is painful and long.  It took me many emails and phone calls to get the guy to get an order set up for what I wanted on the RV14. Then it took a good couple weeks or more to get the harness.  I don't remember if it was 2 or 4'weeks but it was long enough to Irritate me a little.  Still, it worked out...and if you need every lead to be custom

Length it's still the cheapest way to go because buying all 4 or 6 leads is more expensive than custom.  What also would be maybe even more affordable and possibly quicker is to buy a new stock complete harness and then tear it all apart and transplant the cables from one harness to another to make a custom one DIY.  That is my likely plan I guess next time. One benefit is that then you will have a spare harness cap as well. 

Sadly they make it so expensive and tough to keep these mags in service that it gets tempting to remove both but I am

Philosophically not ready to trust 2 electronic ignitions and I definitely won't be trusting the P-Mag, if it EVER comes out, for at least 8-10 years.  If there weren't issues we would have seen it years ago and I know fears were issues. And the talk about impulse coupler problems has me wondering if harmonics aren't their big problem.

Anyone know if the engine gear needs to be changed if I pull an impulse coupled mag and put on a non-impulse mag? Next time I need an Overhaul I think I'll go non impulse.

Anyway, harnesses are a pain so my advice is to care for them well, monitor them for issues, and then come up with your plan or a replacement harness BEFORE you need one because it may take a while to get what you want.

Tim,

 

I note your comment, â€œPhilosophically not ready to trust 2 electronic ignitions and I definitely won't be trusting the P-Mag, if it EVER comes out, for at least 8-10 years.  If there weren't issues we would have seen it years ago and I know fears were issues. And the talk about impulse coupler problems has me wondering if harmonics aren't their big problem.â€

 

The RV-10 is the first airplane Iâ€™ve owned with mags (the RV-8A now has 900 hours on dual pMags).Â  Iâ€™m now pushing 400 hours on the RV-10 and the mags are in need of overhaul.Â  Iâ€™m also on my second set of overpriced aircraft plugs.Â  After careful cylinder balancing I can fly LOP, but above 11kâ€™ the fixed 25 degrees of advance clearly shows itâ€™s limitations. Â 

 

I have some sympathy for eMag on their extended road to produce a TSO ignition.Â  While the experimental market is ready, they see the prize being all those spam cans out there with owners wanting something better than a 1930 era magneto.

 

Considering my personal operational experience with eMag, I will be installing dual six cylinder pMags on the RV-10 as soon as they mail them to me.

That's fine, to each his own.  I know on the 4 cylinders they haven't

been bad, and I'd even be willing to use them on a 4 cylinder engine.

But with previous gearing issues they've had and knowing that the

6 cylinder has different issues in relation to the mag drive,

I personally am not willing to stick something on that gear case

until there are a few years and maybe 1,000 units in the field that

haven't had an issue for a good while.  I'm not willing to be

THAT experimental in my ignition.



I have lightspeed and it's been good, but, it's the granddaddy of

electronic ignition systems at this point.  Yes, there are newer,

but I want to see more track record on them.



For those who like that Gen3 or whatever it is, that attaches

to a mag, before you go that route, you may want to talk to

my buddy Lenny.  He was sold on them from the beginning but

when he finally pulled them off, he actually destroyed them

just so they wouldn't get into anyone elses hands. He

now has a Lightspeed on his plane too.



But that all does not discount your experience on your RV-8A.

I think the pMags have pretty much proven themselves on that

platform, and I have no issues with them there.  And, if you

choose to put them on your RV-10, I can applaud that as well.

SOMEONE has to be the one to take the leap, and if you're

willing, go for it. We'll all benefit from the knowledge.

It's just something that I'm not willing to stick my neck out

on either.  I would also say it's too early to say "hey everyone,

jump on this bandwagon and try them out!" because without

a track record, it could just lead people into something

that could increase our insurance rate.  If it goes well

though, no big deal.

 problem.â€



 The RV-10 is the first airplane Iâ€™ve owned with mags (the RV-8A now has

 900 hours on dual pMags).  Iâ€™m now pushing 400 hours on the RV-10 and

 the mags are in need of overhaul.  Iâ€™m also on my second set of

 overpriced aircraft plugs.  After careful cylinder balancing I can fly

 LOP, but above 11kâ€™ the fixed 25 degrees of advance clearly shows itâ€™s

 limitations.



 I have some sympathy for eMag on their extended road to produce a TSO

 ignition.  While the experimental market is ready, they see the prize

 being all those spam cans out there with owners wanting something better

 than a 1930 era magneto.



 Considering my personal operational experience with eMag, I will be

 installing dual six cylinder pMags on the RV-10 as soon as they mail

 them to me.

 I'd agree with everything you said.



 FIXING a harness would be affordable but these days the prices of

 harness components is just too high and so are the harnesses.  We're all

 screwed if we want it done cheap.  The cheapest option would be to find

 a harness that we can use 1/2 of.  Unfortunately it's almost impossible

 to buy a 1/2 harness now.  So you buy a complete system and only use

 1/2.  If you're lucky and can use a stock part number then it's not

 totally unaffordable.



 But finding a consistent proper length stock harness is tough as slick

 vs Kelly/skytronics don't seem to follow the same lengths.



 Having a custom harness done is not that much more expensive if you go

 Kelly/Skytronics, but, the process is painful and long.  It took me many

 emails and phone calls to get the guy to get an order set up for what I

 wanted on the RV14. Then it took a good couple weeks or more to get the

 harness.  I don't remember if it was 2 or 4'weeks but it was long enough

 to Irritate me a little.  Still, it worked out...and if you need every

 lead to be custom



 Length it's still the cheapest way to go because buying all 4 or 6 leads

 is more expensive than custom.  What also would be maybe even more

 affordable and possibly quicker is to buy a new stock complete harness

 and then tear it all apart and transplant the cables from one harness to

 another to make a custom one DIY.  That is my likely plan I guess next

 time. One benefit is that then you will have a spare harness cap as well.



 Sadly they make it so expensive and tough to keep these mags in service

 that it gets tempting to remove both but I am



 Philosophically not ready to trust 2 electronic ignitions and I

 definitely won't be trusting the P-Mag, if it EVER comes out, for at

 least 8-10 years.  If there weren't issues we would have seen it years

 ago and I know fears were issues. And the talk about impulse coupler

 problems has me wondering if harmonics aren't their big problem.



 Anyone know if the engine gear needs to be changed if I pull an impulse

 coupled mag and put on a non-impulse mag? Next time I need an Overhaul I

 think I'll go non impulse.



 Anyway, harnesses are a pain so my advice is to care for them well,

 monitor them for issues, and then come up with your plan or a

 replacement harness BEFORE you need one because it may take a while to

 get what you want.

     I made repairs to my Slick harness and have some things to share. I

     understand there are various mag models and this may not apply to

     them but mine is a 6351. The pdf document that Tim Olsen shared

     (Champion L-1499B Ignition Lead Assembly & Maintenance Manual) is

     what I referred to. I bought the T-200 Slick Ignition Harness Tool

     Kit from Spruce and three 72" lead assemblies (Kelley S100-72) . The

     maintenance manual is somewhat inadequate in that it referes to

     Slick Ignition wires that apparently differ from either Skytronics

     or Kelley. The Slick wires referred to in the maintenance manual

     have a coiled center conductor whereas Skytronics and Kelley have a

     stranded conductor. On Slick wire you have to insert the little

     screw (that holds the spring) into the coiled conductor but on

     stranded wire it is crimped on. I just happened to have a crimper

     that works which I got from SteirAir to crimp the pins for my

     intercom connectors.



     Since the spark plug ends are already on the Kelley leads, cutting

     them to the right length, crimping the little screw on and then

     pressing them into the mag cap went well.  The Kelley 72" leads are

     somewhat expensive, for me about $85 each so to build a complete 6

     or 12 wire harness would be out of the question. Better to buy one.

     My problem was I couldn't find out how long the leads were in any

     specific kit without pulling one off the shelf and measuring them

     plus I had 3 leads that were long enough so only needed 3. Also lead

     time to have a custom harness made were way too long.



     I see big problems in trying to make your own harness: where to get

     lead wire and where to get the various parts at the mag end (drive

     ferrule, insulator sleeve, crimp on connector and spring). Plus you

     will have to make up the plug end also and get those parts.



     Repairing mine using Kelleys leads worked OK for me but next time

     I'm going to look for someone else to make me a complete harness.
