Starter Power Potential Unlocking the Engine's True Starting Power

When the key is turned to Start, power comes to the relay coil from the ignition switch, and pin 16 would normally be at or near ground voltage. Battery: The battery stores electrical energy that powers the starter motor. A charged battery is crucial for providing the necessary power to start the motor. 60 votes, 48 comments. I know what is a relay and first I understand why a car need it, but when you see how a starter work you ask, ... The live terminal on the battery is connected by a heavy lead to a terminal on the solenoid switch which is operated when the ignition switch is turned. The ... The common starting problems in preludes are related to the main relay and the immoblizer, either of which will still allow the motor to crank ...
