Where are the fuses and relays on a car?
In the fuse box on a modern car, you’ll find a whole bunch of multi-colored electrical fuses and larger, plastic boxes called relays. Fuses are included on all your car’s various electrical circuits to protect components from surges of electricity.
What happens when a fuse blows on a relay?
If too much current flows through the circuit, the fuse will blow — interrupting the circuit and halting the flow of electricity, protecting the components further down the circuit. Relays are remote switches that open or close an electrical circuit.
What should I do if my relay has failed?
Turn the ignition to the “ON” position and jump terminals 87 and 30 the relay is now jumped and the accessory should activate, if so the relay has failed. If no power is observed at either 87 or 30, the fusible link or maxi fuse has shorted.
