Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** is possible new alternator is the problem. What size engine do you have? I'll look up wiring so we can test it. Thanks.
The red and orange/light blue wires at alternator should have power and case should have ground. Regulator is internal so if all of those are good new alternator is problem. If not, one of your fuses are blown. Fusible link E is for orange/blue wire and links C and D are for the alternator. Let me know if you have more questions, thanks.
