I drive a mostly restored 68 El Camino that runs well most of the time, but it has problems with the wiring. The previous owner warned that if I left the positive cable attached overnight, the battery would drain. The battery is also not clamped in place, and so it can slide (and rip out the wires from the starter and alternator from the positive terminal in the process) around if I drive reckressly. I’d forgotten to disconnect the battery a couple of times overnight and the engine would still start. That is, until this morning, when I decided to splice in an additional length of wire to help prevent the wires from getting ripped out. Now the car won’t start at all, and I’m hoping for some advice on how to proceed from here. I’m thinking that the battery is probably kaput, and in the process of recharging/replacing it I should go ahead and replace the old wires and add in a better system to hold the battery in place.
I’m not sure if the process of splicing in an additional length of wire did any damage to any other components though. Is it possible for a spliced wire to damage the starter or ignition? Or should I just replace the battery and wires?
