Jump start structure and method particularly useful for a battery-start vehicle for starting the vehicle or quick charging the battery from a separate source which may have an operating voltage substantially higher than the battery voltage. A starting system operating at a first voltage, for example twelve volts, is connected to a separate source of higher voltage, such as twenty-four volts, through a jumper cable. In one embodiment, a manual switch on the vehicle with the discharged battery must be operated simultaneously with the key switch to start the engine. In another embodiment, an inexpensive control circuit including a normally closed relay located on the vehicle connects the separate source with the discharged battery when a jumper cable from the source is plugged into the vehicle. Once the discharged battery receives sufficient charge, the relay activates to open the circuit between the separate source and the vehicle battery. The normally closed relay facilitates use of the vehicle for jump starting another vehicle.
