Hi,

I attached the wiring schematic of the charging system. If you have several components not working, check the 175amp maxi-fuse in the battery junction box. If that isn't the case, then check fuse 14 in the battery junction box. In addition to checking the fuse, confirm there is power to and from it.

If the fuses are good and have power, go to the alternator, and check the black wire with an orange tracer and the yellow wire with the white tracer for power. Let me know which one does or doesn't have power.

Let me know what you find.

Take care,

Joe
