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.New alternator problem or something else?
It might be a problem with your battery holding a charge sometime an alternator going bad can over charge the battery if you want to check the alternator take it to your local auto zone they will test it for free.New alternator problem or something else?
Have you an automatic tensioner on the belt. It could be bad, if you do not maybe your belt is too loose. try tightening it a little.New alternator problem or something else?
sounds like the voltage regulator but most are in the alternator. the place where you bought it can check it for you . also check if you fan belt is loose . that sounds more why it does that than the alternator cause like i said the voltage regulator is in the alternator usually but go back and have it checked after you check the fan belt firstNew alternator problem or something else?
If you are reading 12V across your battery terminals with the engine stopped that is low. You should be reading 12.6V or higher. Your alternator is doing it's job with the 13.5-14V at idle. Have your battery checked. If you need a new battery get it at the same place if it's still under warranty. They pro-rate the warranties. I just bought one and got $25 toward a new one. Good luck.
