Hello to the group.
I was wondering if anyone has encountered this problem with their f-150... My battery idiot light will light up when my engine rpm reaches a certain speed and will stay on until I press in the clutch and let the engine back down to under that certain rpm. I have checked the charge state when the idiot light is on and off. (light off) At idle up to about 2400-2800 rpm the charge state is around 13.95 volts. (light on) Above the 2400-2800 rpm the light comes on and the charge state falls off to about 12.6 volts. (measured at the battery with a volt meter)
Any ideas?
Thanks in advance.
