I'm New Here
I?ve had a B&C 14V alternator and regulator on my plane for nearly 8 years. The battery voltage has started fluctuating as if the batt was being charged sometimes and not other times leading to a gradual voltage drop. There?s enough charging going on to start the engine when it?s not hot, but the alternator isn?t keeping the voltage high enough to hot-start the engine after a flight. Can anyone advise me of the likely causes and/or things to look for?
