11V!litleboy said:I just changed the alternator on my 2003 Escape, (w/ help o a friend en his tools) I still have some power Issues, w/ AC and Light on, I can see how the panel lights dime, and the AC temperature drops and fan slow down. If I push the gas it goes back to normal, but on the highway The Ac fails the same way. even if I push the gas.
Is there something else to check beside the alternator? any voltage regulator box or something? I bough the recommended alternator from checkers. could it be a faulty alternator? how can I test it? I'm getting:
car off --- 12v
car on, no accesories, --- 13.5v to 14v
car on w/ AC, Hi Beams and stereo --- 13v
car on w/ AC, Hi Beams stereo and radiator Fan, 11V
when the fan turned off voltage went slowly back to 13v
there was no change on the voltage by increasing the RPM.
I'd look at that fan!
