Hello my name is ***** ***** welcome to just answers! I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required. If I don’t answer right away or quickly in conversation I am helping another customer or have stepped out for a moment and will respond as soon as I can. Ok lets get started! What reading are you getting when you check voltage at the alternator main output wire?

Don't have volt meter but factory gauge on dash is running almost in red. Outside of idle. Then maxing out as while step on gas.
Ford Mechanic: Mechanic01, ASE Certified Technician replied 4 months ago

we will need a voltmeter to diagnose this problem, do you have a friend that has one or can you buy one?

Ford Mechanic: Mechanic01, ASE Certified Technician replied 4 months ago

It sounds like the alternator may have been overcharging and blown a fuse, we will need to check a few voltages to confirm anything
