but to me it's called learning. As you add load to your alt. is the voltage supposed to drop. I know my reman is shit and have a new m-m on it's way but I was playing under the hood today and at no load it reads 13.7 but as I added the heater fan it went to around 12 then lights it dropped to under 11 and radio/heated seat put it at 9. Is that normal or just because of a bad alternator.
