I checked the battery because I had to jump start it with my truck and it read 126v. 2 Oct 22 2006.
However this is not consistent with the battery draining overnight. If the current draw is okey cold but excessive hot there must be excessive load caused by the engine. 1 the connection of the cable to the lug is poor or corroded 2 the cable is too small for the current flowing thru it.
People also ask what causes battery terminals to get hot. Why do my battery terminals get hot when I try to start my car. The hot 12 volt cable from the battery to the solenoid makes a connection through the solenoid when you turn on the ignition key which spins the starter.

Is the cable that is getting hot the cable from the starter to the solenoid. The day I brought it home I tried to start it but wasnt getting spark.
