Q&A

Check that the battery connections are clean tight and secure. Check that the ground cable to the engine is good. Perhaps use your battery jumper cables only hooking up the black cable to the battery negitive and the other end of the black cable to the engine (any big piece of metal on the engine) this will give you an additional ground and show you if you have a bad ground. A starter takes about 80 to 100 amps of current to start the engine if the starter is going bad it may draw more current and cause heat but check the connections first.
