The battery relay – exciter wire is working again on my truck. 🔋

Took five minutes to fix. I apparently used copper coated aluminum wire to run the exciter wire. Salt, water air got into one of the butt connectors, dissolved the wire. While I should replace the wire, I instead just stripped it back and fixed the bum connection. If I ever do any more automotive wiring I’ll follow the advice of the experts and not ever use CCA wire, it’s bad news. I am not surprised, I made this mistake previously and had this issue. CCA is much cheaper than copper but it’s one headache after another.
