Seized engine? Perhaps neutral safety switch? Starter solenoid? Bad starter? Iginition switch?
nothing, the starter will not engage, and the voltage bypass to the coil will not be energized.
it is internal to the pcm (engine computer)
Voltage flow into a starter motor, never out of it. Use the voltmeter to measure the voltage at the starter motor before starting to crank and then whilst it is cranking. (Before cranking, the voltage appears across the starter motor relay only.)
The engine computer is the voltage regulator.
The engine computer is the voltage regulator.
The voltage regulator is part of the engine computer.
To send electrical voltage to the starter when engaged.
Check that battery volts are at least 11.8, and terminals are tight. Check for same voltage at starter when key is turned. - If no volts at the starter, the solenoid is faulty. If there is a charge at the starter and it does nothing then it, or it's ground are faulty.
The engine computer is also the voltage regulator.
No
You should locate and test the solenoid. Most have three connections. There is a large cable from the battery to the solenoid, from the solenoid to the starter and from the start switch to the solenoid. The power terminals to the battery and the starter are large and have large cables. The starter switch connection is much smaller. Turning the key to 'start' provides a low current voltage to the solenoid causing the solenoid relay to close and power from the battery cable to connect through to the starter. If that voltage is present then the solenoid or the wiring between the solenoid and battery or solenoid and starter is suspect. If that voltage is missing then the starter switch or solenoid feed line may have failed.
The flow of current has nothing to do with magnetism. It will flow in any direction you want, depending on the applied voltage.
