OFC versus CCA
Copper coated aluminum wire is cheap, flexible and works okay for automotive purposes but not where salt, water and electricity may mix like grounding wires to the frame. Aluminum in such cases will quickly oxidize to white dust, causing resistance, heat, and failure. I learned the hard way, having to tear out that wire.

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.π
Second time this has happened. Also happened in April 2018 (I installed this wire in April 2017).β‘οΈ 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.π₯ 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.
