I'm installing a 12v alternator, Negative ground system, in my 48 coupe. I'm planning to connect the output wire to the stock regulator's B terminal (F & A wires removed).
The alternator is a GM 12si rated at 78 amps. I'm installing a 100 amp fuse in the output line.
The only added accessories will be a stereo (10 amp max) (no amplifier) and H4 LED headlights (approx 9 amps total for both headlights). = 19 total amps above stock.
Will this fry my stock ammeter gauge?
Thanks for your input.
