Relays also can go bad over time and cause electrical problems. The best way to test a relay is to have a helper touch or listen to the relay while you turn the device on. If your problem is not with your electrical component, the fuse or the relay then you most likely have a wiring problem.

It is just a simple (large) wire with two ring connectors crimped on the ends.
