Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, and welcome to just answer. Sounds like the charging system is weak, and it could very well be the alternator. Get a battery charger and charge the battery for a few hours. See if it will then start. If so, get the vehicle to a garage and ask them to perform a charging system test. It should charge at around 13.8 to 14.2 volts, and produce around 100 amps or so of current. If it does not, then replace the alternator.
I hope this helps!
