I just finished fanagnling a 270A alternator from DC power into my 1994 1FZ.
When I start up I get 14.4 or 14.3V, but after a few minutes it drops down to 13.6-13.7.
Is there an external voltage regulator somewhere?
Or maybe a stock ground somewhere that's heating up and slowing everything down?
I've got 1/0 gauge wire from the alt-battery, battery to engine, and battery to the subframe.
Also, I have 2 optima yellow top batteries. They are both good; I get 12.8-13.1V when the engine is off. I just have a simple parallel connection for them, no isolators. I also have a 10 Farad capacitor.
All these voltages are with the stereo off.
What can I do to get the voltage to stay at 14.4? Just more grounds?
