Default Hot Battery Terminals?

Hi All -

I went to start up my 69 convertible yesterday and had some significant issues. It eventually started and I pulled it out of the garage only to have it shut off. I tried to restart it with no luck. Eventually, it stopped cranking. My initial thought was the battery was dead, but the radio and clock were still on. I have a kill switch on the positive terminal, so I checked it to make sure it was tight and was surprised that it was extremely hot to the touch - hot enough that I jerked my hand out of there. I kill the battery every time after I drive the car and I can't ever recall it being hot.

Has anyone ever experienced anything like this or know what the issue could be? Thanks in advance.

The radio and lights don't take very much current to operate; so a battery very near death can still operate them. But, a weak battery will not have enough current capacity to start a car...or it will overheat when grinding slow while 'trying'.

You have a very weak, old, risky battery. Replace it.

When connections get hot, it is typically due to high resistance. Hi resistance is caused by carbon deposits resulting from arc created during connection/disconnection. If you can disassemble the switch and clean where the 2 poles make contact, you might clear up all the issues.

Having said that, 7T1vette makes a good point which ALSO may be true.

Great, thank you. I'll replace the battery today. I had it recharged a few months ago, so I bet that is it. I'll also clean everything up on the switch. Thanks again!

Shouldn't have to use one of those useless battery "shut off" switches. If you have no battery drain issues they are useless. Your battery will last no longer with it than without it.
