Answer1. Make sure the engine will still turn. If you have the right tools turn the crankshaft by putting a socket on the front crank bolt, behind the belts inside the pulley. If you can't turn that then you may have a frozen engine.
2. Make sure the battery cable connections are clean and tight, both at the battery and on the engine.
3. The positive cable getting hot is the result of high amperage or resistance, either which could be caused by 1 or 2, or by a stuck or defective starter.
