There are 2 fuses in the harness in the engine compartment. They are in small rubber holders that look like connecters. Check each one. They use 4 amp fuses. With a test light there should be current on both sides of the fuse holders. This is usually the cause of this gauge from not working. Sometimes the fuse holder is corroded. You can replace it with an universal fuse holder. You can put a 6 amp fuse in them if the higher amp alt is blowing the fuses.
