Alternator Conversion Question

[Willie Krash]

I wrote in my reply above that 7.7V is equivalent to 15.4V on 12V.
Is that a problem? Yes and no..For some batteries you are very close to gassing the battery. 16V does the trick.
Where you live and how long you drive is an issue. As Mike K said no temp compensation.

This is why I mentioned Alaska. Cold weather will produce a higher voltage that ramps down with heat. Mike alluded to this.
As to the amp gauge returning to zero sure but remember the set voltage is 7.7 and on an analog regulator it is either on or off. It strives for 7.7 and when it reaches that it shuts down. This happen very fast but the end result is 7.7V. The freq that this happens is driven by battery and loads.

Seem a little hot for me, on a long drive particularly so.
Can you get away with it, sure. If you drive 15K miles a year a little dicey.
I don't know if you would know or not but it well may affect battery life, see conditions above.

I wouldn't worry about it for casual driving or otherwise. On paper tho' I don't like it.
