Thanks for your response, Rich! I use fuses, so CBs aren't the problem. I've added an avionics switch about 6 months after I got the plane, and nothing changed. The issue has always been the same, so I think that rules out the switch. With regards to the smoke, when it happens, it can be a lot...more than any small wire can produce. That's why I'm thinking it is coming from a larger wire on the back side of the engine. I don't see any sign of burning wires, so at this point I'm thinking the only two places burning could be going on is near the alternator/stator area and/or inside the regulator/rectifier. Does this make you think of anything else, or do you know how I could conclude anything more about the stator other than pulling apart the wiring harnesses and checking connectors there? Any other thoughts? Thanks, Art.
