RHO Posted May 20, 2019 Report Share Posted May 20, 2019 The negative battery cable terminal in my '83 Avanti gets too hot to touch even after just a few miles. Is this normal? Link to comment Share on other sites More sharing options...
Gunslinger Posted May 20, 2019 Report Share Posted May 20, 2019 It looks like you should replace the cable and end. If there's a buildup of resistance from age in the cable or from a dirty cable connection on the battery weird things can happen. I'd start with a new cable and end and have the system checked to make sure the voltage is in the proper range and not charging too high. Make sure all connections are solid and secure. Spraying some wire dryer on the battery connection and the engine block or frame connection will help keep corrosion form occurring. Link to comment Share on other sites More sharing options...
studegary Posted May 21, 2019 Report Share Posted May 21, 2019 Those clamp on terminal ends are designed to be used as a temporary repair. I am going to guess that you have corrosion resulting in resistance. As said, replace the cable with a proper, new one. Link to comment Share on other sites More sharing options...
RHO Posted May 21, 2019 Author Report Share Posted May 21, 2019 (edited) OK, thanks. I installed that "quick release" terminal fitting so as to disconnect the battery due to a battery drain somewhere.

RHO Posted May 22, 2019 Author Report Share Posted May 22, 2019 OK, that is the cable/cable end on the car when we acquired it. I haven't been able to find a picture of the correct cable in searches. Link to comment Share on other sites More sharing options...
Avanti83 Posted May 22, 2019 Report Share Posted May 22, 2019 Nothing special, It's just like any ground cable you can find at a parts house. I generally just buy the biggest cable they have and bolt it on. I make my own when it comes to mounting the battery in the trunk but I use soldered connections. The clamp on like you have is very susceptible to corrosion. Link to comment Share on other sites More sharing options...

Footer Posted May 23, 2019 Report Share Posted May 23, 2019 I had corrosion in my positive cable running across the firewall to the starter. Couldn’t see it under the insulation but a new cable made an amazing amount of difference when it started the car. Mike Link to comment Share on other sites More sharing options...
dynolou2 Posted May 24, 2019 Report Share Posted May 24, 2019 As to battery drain, power to the engine computer is on all the time unless battery is disconnected. Lou Cote Link to comment Share on other sites More sharing options...
