Short-Circuit Check

WARNING: This page is about a different car, the 2004 Mitsubishi Galant. However, it is still accessible from the selected car via links, so may be relevant.

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.

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