[Wrenchbender Ret]

You have a mess there. There is a 10-12 gauge purple wire that goes to the S term on the selinoid. A small yellow or white wire goes to the R term. There may be 2 or 3 10-12 gauge red wires with fuseable links going to the bat cable term. To really make it right you are probably going to have to snatch it all out & rewire it.
