Alternator Field Circuit Breaker Tripping.

[Paul462]

The broken P lead turned out not to be the problem, but rather it was a broken impulse coupling spring in the mag. Had to take off the starter and some baffling to remove the mag. Mag checked out OK - now let's go flying!

After landing, the regulator now maintained voltage at 27.5 - 28 v even with the pitot heat, landing & taxi lights on, and everything else I could turn on, so long as RPMs were around 1300. Hot dog, it may be fixed!
