Great to hear you’ve isolated the issue. Keep us informed when the new coil goes in if the problem is solved!

the saga continues. I did put that coil on, didn't fix it. I got me a timing light and put it on t1 and it wasn't firing. checked t-2 and it was firing. what the heck. that's on the same coil. can't be the trigger it runs both on or should I say fires the coil with one trigger for t1 and t2(let me know if I'm wrong) . so back to the cdi module. this is the new one I got about a year ago with soft start. my thinking is this thing is bad. so what I'm going to do now is take the module I took out and put it in the freeze for an hour and put it on ice and take it to the airport and install it and hopefully be able to start the plane. you see it failed and wouldn't work until the engine has 2000 rpm. it is said it will start working if put on ice for a bit. this is a green label cdi. I will see if it will start and have the timing light on that plug. got me baffled for sure. I did check the ohms for the triggers, they are all the same so should have good wires going down to the triggers. wish me luck, cus that is what this is turning into.

sorry to hear the frustrations continue. It’s odd as a single coil is triggered by a single trigger wire from the cdi. If one of the plugs on that coil is firing, the trigger from the cdi is good. Have you changed out the spark wire and plug boot to see if those have an internal short? Napa auto parts will have some 7mm wire you can pick up for a few buck to make a test wire.
it now has a new coil for that t1 t2, came with new secondary wire and I bought new end caps. I did change to the other plug in for the triggers and that made that t1 fire on the timing light. if it is in the cdi it will be a total weird happening, things like that happen to me. lol anyway I'm going to try and install the old cdi and see if it will fire with things hooked up normal for the A circuit. Hope that does good. I'm not going to buy another cdi, they lost me on that one. factory anyway.
