Alt light fix, 85 westy


 

Hi all, I’m trying to get the Alternator light working correctly as it currently stays on. I’ve looked at Weide guide but my 85 has a different style fuse panel and I have searched this group and can’t seem to find my answer.
?
Some background info:
85 westy
frankenmotor
previous owner installed solar and removed fridge.
?
Under the driver seat I found 2 blue wires (one labeled radio and the other unlabeled but screwed to the panel with a few other red wires and a wire labeled charger (one of these rant to the aux battery under the bench seat). I disconnected this blue wire and the alt light still stayed on after starting the car.?
?
I found this guide on Busaru as well as his supporting video on YouTube that might be a fix by installing a relay at the fuse panel by cutting the blue wire there (which I located on my van) but wanted to check with the group before cutting any wiring. Thanks in advance! This group has been an amazing resource!

I think I may have solved my issue. I found this black wire soldered to the blue wire mentioned by Busaru behind the fuse panel. Disconnected the wires and now my alt and oxs light come on when I turn the key and they both turn off when I start the car. Next up is wiring the CEL to the OXS light

Hey Anthony.
I’ve got a pdf out on my website showing how I used the existing Vanagon wiring and tied my Subaru mil/cel light into the oxs circuit.
Here it is….


Best,
Brent
