Important: Do not try to start the engine without a battery in it. You could cause dam- age to the electrical system. If the engine does turn over, but never starts up, there is not a problem with the starting system, there is a problem somewhere else with the vehicle. STOP cranking the engine until the other problem has been diagnosed and corrected. NOTE: The GFCI outlet should not be used while the Charger is in the Engine Start Mode. 16.
