Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, is the check charging system light on now? What kind of ford is this, year, model, engine size? IS the vehicle charging or is it going dead overnight? WIll it restart on its own once you shut it down?
Ok depending on where you got the altenator, it is not uncommon to get a defective aftermarket altenator, so it is possible the replacement unit has failed. Need to verify using a volt meter that you are getting battery voltage at the main altenator battery lead and at the smaller altenator connector at the back of the altenator. If you dont have power at these two connection, you have a blown fuse or open wiring issue to the altenator. im thinking the replacement altenator has just failed.
Need to verify when warning lamp comes on if it is actually charging. Napa should be a good altenator but anything is possible. If it is charging but the wanring message comes on and off, it could be a defective diode trio inside the altenator. Make sure the connections to the battery are tight,the wiring to the altenator isnt damaged, and the serpentine belt is tight and not slipping on the altenator, causing a loss of charging.
