FWIW - I have had every mini switch in my plane(-6A) eventually fail by 1000 hrs.  I now use these big honkin switches and have no more problems.  I suspect that the switch that comes with the autopilot is quitting now, but it will be tough to debug or replace.

Well N96PM makes noise again. It's running like .hit, but it IS running.
 
The (final) starting problem was the secondary injector switch. I found low voltage at the secondary injectors and traced it back to the switch - serves me right - it was one of those mini radio shack switches. They're supposed to be rated for 10A, but the innards of these things are pitiful. I know because the switch fell apart in my hand. Two big fat DPDT switches later and the engine fires up right away. But I'm pretty sure its running on one rotor, and THAT one isn't running well - very rich, I think. The engine shakes more than it ever has and doesn't respond hardly at all to throttle changes.  Just sits and burbles at about 1600rpm.
 
So, I have a bit more debugging to do, but at least it's a step forward.
John
