Relay

1. Measure the resistance between terminals 3 and 5. If the resistance is less than 5 ohms, replace the relay.
2. Connect a jumper wire between relay terminal 1 and battery positive terminal.
3. Connect a jumper wire between relay terminal 2 and ground.
4. Measure the resistance between terminals 3 and 5. If the resistance is greater than 10,000 ohms, replace the relay.
