2. Short-Circuit Check

Because the fuse has blown, it is probable that there is a short circuit. Follow the procedures below to narrow down the short-circuit location.

1. STEP 1. Remove the blown fuse and connect the test light across the fuse terminals (Circuit switch: OFF). 

   Q: Does the test light illuminate? 

   YES :  Short-circuit exists between the fuse block and the switch. Repair the harness between the fuse block and the switch.

   NO :  Go to Step 2.

   Q: Does the test light illuminate? 

   YES :  Short-circuit exists between the switch and the connector. Repair the harness between the switch and the connector.
