Put on 3 alternators, a brand-new battery and starter. And the battery light keeps coming on telling me to check the charging system.

Hi,

Is the battery staying charged or does it get weak? If that is the case, I need you to check something for me,

At the alternator, you will find a black wire with an orange tracer and a white wire with a black tracer. Both of these wires should have power at all times. I need you to confirm they do.

I attached the charging system wiring schematic below so that you would have a reference. I highlighted the two wires I am referring to.

Let me know what you find.
