Corrosion once again eat the truck cap’s ground wire off the frame’s terminal connector this morning. I noticed voltage drop in the truck cap over the weekend (suggesting resistance in a wire) and this morning suddenly I discovered that I had lost all power back to the cap.🔋

Second time this has happened. Also happened in April 2018 (I installed this wire in April 2017).⚡️ I thought it was a salt issue, but happening in the summer, I think wire is copper-coated aluminum and the aluminum is oxidizing from water plus electricity (and maybe the aluminum and copper being dissimilar metals.)

Annoying. I am thinking i am going to have to replace the wire with pure copper, and figure out how to heat shrink it, when I am not near the gas tank.🔥 The question being how to fish the wire connector through the hole in the truck bed, although I have ideas — maybe run excess wire through the bed and use that wire to heat the shrink wrap not near the gas tank.
