Wiring problems before inspection

[VetteVet]

On the back of the ignition switch is a 12 gauge brown wire that powers all of your accessories. This wire may not be connected any longer (open) to the fuse panel. There is no fuse for this wire or any behind the fuse panel. All the circuits it powers are fused separately.

The wire is pointed out by the black arrows. Notice also that the small tan striped wire that connects with it at the key switch is the exciter wire for the alternator and it is probably open as well. This is probably why your alternator is not charging until you rev up the engine. This is a resistance wire (10 ohms) and is needed to protect the diode trio in the alternator, so you need to get it working.





This is the wire at the fuse panel powering all the fuses for the things that aren't working.
