Will the ground stop working if the chasis is too hot?
I have recently noticed that my amp will not turn on with my car sometimes. This only happens when my car has been sitting in a hot place for a period of time. At first I thought that the amp was getting too hot, so I installed a fan. Yesterday, however, I figured out that there is no current going through the positive line and the ground. I tested this with a small light. I woud assume that since my car started, power is still pulling from the battery. So, the only problem would be the ground. So does the ground stop working if the place I grounded to the chasis gets too hot? Is there a way to prevent this?
