HO Alternator - Weird Problem??
#21
I can't say I know the oscillation frequency exactly, but I would estimate from the pulsating of the headlights, at least 5/6 times a second, but it was a clipped DC waveform that varied according to engine speed. The peaks and valleys would increase the faster the engine ran. A variation of up to possibly over 0.7v from peak to valley.
It wasn't true AC voltage because it didn't cross the 0 axis into negative, and all readings I believe didn't show over 0.3 volts of AC voltage.

it's 2.1V per lead acid cell at full charge. 7 cells would be 14.7V your alternator voltage would have to be bumped to at least 15.7-16Vto be effective as a primary power source in the car.....great for the audio stream, horrible for anything else electronic in your car.

There wouldn't be as large a gap between battery and alternator, and not bad for the electronics.

a lead acid battery ahs to sit at 100% charge to have any kind of longevity nless it's a deep cycle battery, Also with that little of a voltage gap between alternator and battery you'd be puling from the battery partially with every voltage dip causing it lose charge.
You'd fighting the fight to zero... you'd always just be fighting to ke the battery topped up.
also your alternator charges at 14.4 with minimal or no load. usually under any kind of load it's 13.8V.
