I have been flying problem free with my nippon internally regulated alternator from Vans. Today I switched on the master before starting up and noticed voltage at just under 12v on the voltmeter. I started normally and before switching on the alt. field switch the voltage climbed to 14v+ (voltage has not changed previously until switching on the alt). When I switched on the alt the voltmeter pegged out immediately at 16+++. No other switches, lights, radios, or transponder were turned on. I shut down, repeated, same result. Shut down and went home. 1st time this has happened. I watch the guages religiously. What would cause this? thanks, Jack
