Hi,

We need to check a few things. First, there are two fusible links that send power to the alternator via a black wire with an orange tracer. I need you to check that wire to make sure there is power to it.

Next, check fuse 18 in the battery junction box. In addition, confirm there is power to and from it. If there is, then go to the alternator and locate the white wire with a black tracer. Check that for power as well.

Here are two links you may find helpful:

I attached the charging system wiring schematic below so that you have a reference. I had to cut it in half to make it readable for you, but I did overlap the two so you can follow from one to the next.

Let me know what you find,

Take care,

Joe
