Hi there,

I was wondering if you did connect the AFS RPM sensor on the magnet or the LS ignition, or is it even possible to wire both and choose via software where the signal comes from.



Thanks

Michael

Jim, I tried everything to get my Lightspeed to talk to my AFS.... with no success.  Robs people were great, but still nothing.  I have a backup Vans tach that I had to hook up using the cable and such out of the back of the motor.  What did you do to get it to work.  Gotta be specific here... Not at the hanger, so I can't cite pin numbers... hopefully you can...   Sure would be nice to get it to work,

Even though AFS has a provision electronic ignition tach, the harness that come with the AFS does NOT include a pin or wire for for it.  You have to add this additional wire if you want RPM indication from the electronic ignition on the AFS.  Did you add this additional wire from the LS input connector pin 6 to the AFS EM harness pin 33?

William,



I don't have my wiring diagram in front of me right now, but quickly looking at your page 4, why are you trying to connect both your mag and LEI inputs?  I must be missing something.



I have a Mag on the Left and LEI on the right.  My rpm readings come from my Left Mag and I always have a reading no mater what I have selected, L, R, Both.  If the engine is turning, I have an rpm reading.

Ah, how about doing a mag check with other than your ear! --or being able to select from which device you want RPM indication.  Why would you not?

William,

I think you are missing a key point here.  You mount the sender on the mag and it detects magneto revolutions.  Maybe you have a different mag but on mine the sender mounts in the hole that the black vent plug goes in.  It has nothing to do with the fact that the mag is engaged or not engaged.  Unless the mag shaft breaks or the mag falls off the back of the engine, the main shaft of the mag will be rotating and the sender will detect the rpm of the shaft and therefore the engine.

In this configuration, the left mag can be on or off and the right LSI can be on or off, as long as the mag shaft is turning, the AFS EM unit will indicate the engine speed.

My RPM uses the supplied speed sensor from AFS in the right mag vent.  I wired the LightSpeed but use the input from the mag mounted sensor as the primary RPM input. The plan is to eventually replace the mag with a P-Mag / E-Mag once the 6 cylinder version become available.  I would like to have an ignition system that does not rely on 12V to power it once running.

Gary,

 Â 

 Yup, I'm confuse by the question andÂ think I missed your point again.

 Â 

 AFS provides for RPM input on PINs 16,31 &Â 32 with the included mag sensor--I wired that.Â  AFS also provide for RPM indication with Electronic Ignition on pin 33 --so I wired that also.Â  This gives me the option of which device, mag or Electronic Ignition to get the RPM indicaton from.

Rick,The LightSpeed will work with voltages down to 5 volts (if I remember correctly).I have not gone to a dual battery system but opted for a single larger amp hour battery.My plan is to always keep a engine operated ignition installed just in case.

Well, when it comes time for overhaul on the mags, if you don't succumb 

to the siren song of electronics, you might consider a switch to the 

more reliable Bendix which also have hotter spark. Personally, if I can 

swing it, will aim for Bendix 1200 series for my engine...about the best 

high altitude mag out there.

... I'm planning dual mags.... trying to make every decision now to keep systems simple, redundant and light.  I'll have an all electric panel with two AFS Advance Decks each with their own back up battery, single battery in the back and single alternator.

		  Gary,

 Â 

 Yup, I'm confuse by the question andÂ think I missed your point again.

 Â 

 AFS provides for RPM input on PINs 16,31 &Â 32 with the included mag sensor--I wired that.Â  AFS also provide for RPM indication with Electronic Ignition on pin 33 --so I wired that also.Â  This gives me the option of which device, mag or Electronic Ignition to get the RPM indicaton from.

I think I see what you are also trying to say.  You will go into setup and tell it which source you want?  I don't think we can display 2 sources at the same time, can we?  Have not looked.  And if you switch off the LSI as in a mag check, with LSI selected in setup, will you get any RPM reading?

While I loose some redundancy and a backup option, I went with what I think is a simpler solution and just went with the single source.

If I lost RPM's at run-up, it would be back to the hanger, but I have flown the plane enough now that if I lost it on TO or enroute, I know I would be able to land uneventfully.

Yes, I added the wire to that pin... that was the easy part.... then AFS told me I needed to install a 10k ohm resistor in series, and run a leg to ground. did that. still nothing.

 So apparently all you did was run the wire from LS #6 to AFS 33?

 Sure wish it had been that easy for me.

  Even though AFS has a provision electronic ignition tach, the harness that come with the AFS does NOT include a pin or wire for for it.  You have to add this additional wire if you want RPM indication from the electronic ignition on the AFS.  Did you add this additional wire from the LS input connector pin 6 to the AFS EM harness pin 33?

  Have the same configuration Lightspeed on the left and magneto on the right.  I wired the AFS tach to the lightspeed ignition.

Sorry Jim, I forgot to sign my email.... it was me who had the questions on the LSE/AFS tach hook up.  Where are you located?

 Michael,



I will swing by the hanger today and give you more details.

Hi there,

I was wondering if you did connect the AFS RPM sensor on the magnet or the

LS ignition, or is it even possible to wire both and choose via software

where the signal comes from.



Thanks

Michael
