Still having some issues in getting the Plasma III to fire correctly. I suspect I may have something wrong at the switch, or at least that is where I am starting my continued troubleshooting. I have been through the archives and saw several variations. I have the ACS keyswitch, Unison slick mag on the left and the Plasma III on the right. Does anyone with the exact same set-up working for them have a wire by wire connection diagram and a pic they can share?

That's what I have and documented on my site, but don't trust it blindly because although it works great for me, it certainly isn't standard and doesnt make sense totally to me. I found it from another guy it worked for.

Hi Eric:
I don't have my info handy at the moment but I wired mine up using Tim's
(myrv10.com) as a reference and it works fine. search for "Electrical
system tips" then Wiring a keyswitch. Should take care of it.

Tim, I did base what I have on you site. Much of what I have used as a reference has come from you and Deems. I am just not getting any spark from the lightspeed, ever. So I am fishing to see how someone else may have cracked this nut.

If I remember right, the keyswitch wire is the only wire on that
whole connector on the Lightspeed, right? If so, I think you
can just disconnect that connector, and that would give
you an always-on Lightspeed for testing. At that point
you could either:
A) Be really darn careful and start it up and see if it's
running on the lightspeed when you switch off the mag.
And kill it with the big mixture pull.
B) Pull all your plugs and wires and spin the prop and
see if the lightspeed sparks jump between the coils.
With no compression and no plugs to spark, it turns
real easily and you can see if the lightspeed sparks.
I remember in my garage spinning the prop and watching
them spark to determine spark order.

Tim, It will fire like that. I had worked through that the first time I was having issues with it kicking back the engine during crank. Although I could start the engine fine with the CB pulled then reset it and everything ran fine. I know it will fire, it is just a matter of getting it wired right on the keyswitch so I am getting the correct ignition retarded and the engine starts. The first time I had it wired to the sheet from ACS. The second time I wired it as you did, and I am getting the Plasma constantly disabled. I have checked the switch with a multi-meter and it appears to be functioning correctly. I am going to SunNFun this weekend so I may do some poking around down there and chat with the Stein and his folks. I think my big issue is going to be where to jumper the key switch and where the p-lead form the mag ground go.

Eric did you verify the gap between the magnets and the sensor-this can be very critical and can lead to intermittent problems-Just a thought based on my experience-Jim

Well, it sounds like you are troubleshooting right...it'll
be interesting to see what you find in the end. It's probably
just one misplaced wire, or something small.
One thing about starting...I'm not 100% sure, but reasonably
sure that when I crank, my lightspeed is on. I've started
it before with the lightspeed disabled and it takes more
to get it started. I have never had a kickback issue. I'm
a bit confused by this all because I know some people
have talked about kickback before. I can tell you that
I have an impulse coupled mag on the Left, and Lightspeed
on the right. The ignition system is one of the things
in my top ten list of the things that I love about building
my own plane...it's a huge benefit to be able to use
such things.
