How do you start an engine bypassing the starter?

To start an engine by bypassing the starter, you can use a jumper wire to connect the battery's positive terminal directly to the starter motor's terminal. Ensure the vehicle is in neutral and the parking brake is engaged for safety. This method sends power directly to the starter, engaging it to crank the engine. However, this should only be done in emergencies, as it can cause damage to the electrical system if not performed correctly.
