A word of caution - don't cause a relay to click continuously. The arcing will kill it. Then when the original fault is found and handled, the relay won't work and will need to be replaced. This is also true of the starter solenoid which in essence is just a large relay.
Wanted: Dead, smashed, crashed or trashed gauges
