My old 105 amp alternator wasn't cutting it in my race car and after about 200 miles with all lights and fans on, I could see battery voltage dropping down around 11.1 volts. It seems like once we hit 10.9 or 10.8 volts, the electrical system starts to 'self correct' and things start to shut off.
So.....I installed a 170 amp alternator and now voltage and charging is great. Maybe too good. At idle with everything on (LEDs, 5 fans, radio, GPS, engine, fuel pumps etc) we are putting out around 14.4-14.9 volts at idle. Am sure at higher RPMs it's even more.
Question is - how much is too much voltage before we start roasting batteries, components, etc?
