Have Ford Questions? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I can help you.I have been in this business since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. Please be patient!I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.
See attachment for your cure, it works for me all the time to find battery drains. Also confirm that the alternator is working at high demands.
I understand, we just need to make sure that it's working right on a bench test first, then on the truck itself. If it passes a bench test, then we either have a wiring problem or computer problem with the truck. That's how we need to isolate the charging system. If all that is good, then you have a drain and need to follow the instructions I sent you. Thanks again and please don't forget to rate me and keep this link if you need more help with this later om.
