my son has a 2005 350z, and the positive battery cable is way too hot. any ideas whats heating it up? so hot, will burn the fingers. he said the negative cable too hot as well. also, the car wont start, lights and gages work. Starter doesnt even try to bust off. Have checked battery, has good charge.

 

 

 

If its too hot, then don't touch it.

 

Factory or aftermarket cables? Are there any aftermarket accessories like amplifiers, etc tapped into the main cable?

 

You said the starter won't start? it's probably Starter Sol is stuck on creating the cables to get hot. Probably needs a new starter. I've had this happen on a customers older toyota....touch the starter if you can and if it's hot to the touch as well then that is your issue. Otherwise....there is a short somewhere.

 

High resistance or high current somewhere. I would check your grounds for corrosion/broken wires and also check your fuses to ensure nothing is blown/melted or replaced with a higher amp fuse. Also, a faulty starter that is drawing excessive amount of current can cause your no start/hot cable condition.

 

hubby and bro-im-law found out problem. engine locked up. they got it to start, ended up with pieces of piston and engine block in the yard. this car is waiting for new motor. but son went and got a 2011 370z. thans yall for the replies
