Over Voltage with New Battery Disconnect Switch

This is what Im asking about "I also hooked my alternator charge wire to the disconnect switch" How did you do this"?

I disconnected the original black wire connected to the alternator and then connected a 6GA wire to that post on the alternator and ran it to the back of the car and connected it to the side of the switch where the battery is connected to. Very similar to the photo in the first post

Got it. So you are bypassing the standard charge path that 67DArt273 posted, correct?

Yes. I am bypassing that original black wire as I just disconnected it and tapped it off. I assume that's what the photo in the first post's photo meant when it said "disconnect fatory wiring"
