Fuse box diagram (fuse layout), location, and assignment of fuses and relays Mercedes-Benz G-Class W463 (200 GE, 230 GE, 300 GE, 500 GE, G230, G300, G320 and G36 AMG) (1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997).
Checking and Replacing Fuses
The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the components on the circuit and their functions stop operating. If a fuse has blown, the inside element will be melted. Blown fuses must be replaced with fuses of the same rating, which you can recognize by the color and value.
If a newly inserted fuse also blows, have the cause traced and rectified at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.
Notice
- Before changing a fuse, secure the vehicle against rolling away and switch off all electrical consumers.
- Always disconnect the battery before servicing high current fuses.
- Always replace faulty fuses with the specified new fuses having the correct amperage. If you manipulate or bridge a faulty fuse or if you replace it with a fuse with a higher amperage, the electric cables could be overloaded. This could result in a fire. There is a risk of an accident and injury.
- Only use fuses that have been approved for Mercedes-Benz vehicles and which have the correct fuse rating for the system concerned.
