Starting issues

[Md150178]

my 71 is having some electrical issues at the moment. When I try to start it the starter either just spins or it clicks. After trying it a few times it may turn over. After it does turn over and it’s runnibg it won’t turn off. I have to choke it out.
I have cleaned my ground off the battery and replaced the starter with an after market one. I may have the original rebuilt if that is the issue.

It’s also causing my accelerator cable to get hot and melt when it just clicks.

I don’t see how cranking your engine over could melt your accelerator cable. Unless someone hooked it up so current flows through it.

Here are pics of my 71 ignition switch and connection at starter. Make sure your big ground cable from Battery negative has a good ground to frame rail.

Also be certain the two white/black stripe wires have a good ground at the alternator voltage regulator. It’s on the firewall just below the brake booster.

I see now you metioned the ground is cleaned. Did you use new + & - cables or make sure corrosion hasn’t worked up into the old cables? I’ve seen corrosion creep >12inches.

Can you post a picture of where the accelerator cable melting? Never hurts to posts pictureds of how you have it wired, someone might spot what’s wrong.

Sounds like you have a number of issues. There is something back feeding the IGN circuit, which is why you can't turn it off with the key, probably the alternator. You also have a ground issue that is causing your accelerator heat issue. Verify all your grounds first, then you need to track down the back feeding.
