You can just remove the fuse and test. A blown fuse is NOT needed to test.
If one or both batteries still get discharged, then you'll know that you have a bad battery or two.In the meantime, I will just be taking the negative cables off the batteries, when I park it.
Then remove the wiper motor to see if I can R&R it to make it work.
Totally corroded. Not doing anything at all when I turn it on.If you can't let me know. I might have one kicking around I pulled off a parts truck if you need it.
What's wrong with it, what's it doing?
Sometimes the easy things can give amazing results.Great technical comments guys. I'm learning alot on here. Also some dummy comments from me. I recently discovered that my negatives were really corroded. I replaced with 0gage and cleaned all the grounding points with a wire brush and connected everything back up. Also used big wire on the big 3. Both batteries to frame, alt to frame, and block to frame. Solid power now. No flicker or random arcs.
