I used to use Solenoids off of Fords...they take alot more punishment...
This is basically how the starting system works.
You have a starter, grounded to the engine, and therefore the Frame, thusly the Negative battery post.
You turn the key switch, and it sends a low amperage 12v current to the Solenoid. The solenoid then completes an internal circuit.
The circuit starts at the battery, runs to 1 side of the solenoid Then from the solenoid to the starter.
If you hear a CLICK, the internal switch is working, and either there is a failure internally, or there is a problem between the solenoid and the starter.
One way to check is to touch the 2 wires that go o nthe solenoid together. If the engine cranks, it is the solenoid.
If there was no click, it could be any of the safety switches, key switch, or solenoid itself.
If there was no click, you would have to go pickup a circuit light tester, makes trouble shooting a startingt system easy. Just start at the battery, and make your way to the starter, see where the power stops.
