Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.
If you take your 12 volt test light and or a volt meter with the engine running and back probe the yellow/white wire as well as the black/orange wire and the green/red wire at the alternator do you have voltage on all three?
Are you checking this with the engine running? All three wires need battery voltage.
It would be very odd if all three wire are only reading .5 volts if you have 12 volts at the battery. If you can recheck it and let me know the results we can work from there.
Yes check the fuse link A and B that should be connected to the starter solenoid on the same post that the battery cable connects to, this fuse link power both the Black/orange wire as well as the yellow/white. See the wiring diagram for testing reference in the link below.
Okay so which wires at the alternator are still not getting voltage?
Okay if you look at the wiring diagram I sent you you well see there two fuse links in the harness to both of these wires. Fuse link A and B. If you have no power on both wire then I would suspect your fuse link is blown.
See it in the link below and be sure to print it out as it dose time out over time. Fuse link A as well as be are located at the starter solenoid at the same post the positive battery connects to. See the link below.https://dl.dropboxusercontent.com/u/104923897/Alt%20Dec%202.pdf
No, there are a separate group of wires that connect to the solenoid on the same post as the cable coming from the battery.
