E-mag suggests a 9v battery will sufficiently power a P-mag for starting. Has anyone successfully tried this?
A friend's PC-680 internally failed when he attempted a start. Buss voltage was 12.6, but dropped to nothing with any load over 1/2 amp. Fortunately, he was at his hangar. So the question arose about how one would one get out of this predicament in remote location. MacGyvering a 9V patch would be easy enough (if you had such a battery). Biggest hurdle I foresee is priming a cold engine (the aux pump isn't juiced) or the mad propping for a hot start.
