Is it normal for the alternator to get hot? If the alternator dumps a lot of amps into the battery in an attempt to recharge it but the battery cannot hold the inflowing charge, the alternator can get pretty hot. In fact, it may continue to rise in temperature until is just burns out.Apr 9, 2010

Why do stator wires get hot? This is caused by resistance. Resistance is caused poor or under gauge wiring or bad connections. Check the ground at the frame crossmember just under the back of the tank. Make sure the connector between the stator and the R/R is tight.May 5, 2013

Why does my positive battery cable get hot? If one cable is only getting hot then you need to clean the connection on both ends and/or replace the cable. Any excessive resistance of a cable will dissipate heat. Once copper gets too hot it will always have an increased resistance. No, the starter should not cause the heat in the cable.Jun 26, 2010

What happens when a wire gets hot?

Once a wire gets hot, the heat can travel along the wire until it gets to an electrical connection, such as a plug in a wall socket. Once the connections in the plug get too hot, they melt and expose bare wires. These ultimately cause a short circuit, which produces more heat and melts the plug connection.

What would cause my battery cables to melt?

Why do alkaline batteries overheat?

As the vapor pressure inside the battery reaches a critical point, the sheathing ruptures. In most cases, the battery will simply leak, but if the vapor pressure is high enough, it can explode. Alkaline batteries from reliable manufacturers are vented to allow built up heat and energy to dissipate.
