Alternator wiring
I have a battery light on in my 2002 f550 7.3 that I’m trying to get to turn off. While trying to diagnose the issue I found that the BL OR wire going to my alternator has no power at all, running or not. Everything I find says that it should always have power.
The alternator is charging at 13.5v after a few minutes of running and the batteries are good. Would this be the cause of my battery light and where does this wire go I’ve looked diagrams and have a hard time translating that to under the hood.
any help would be greatly appreciated!
