Frank,

I had the copper coated aluminum cables on my 79 Cadillac & the negative cable fried the air conditioning dash controls, VERY  high resistance All GM’s more than likely to save weight for better gov fuel rating. (Junk!). Replaced with xhhw type wire & soldered my own terminals on. My 62 Chevy P.U. has the same for easy 30 years. Can be bought at electrical supply houses in any size. I chose xhhw for the best insulation. Mine was “rabbit” wire. Came from wire pulls that always ran away :)!
