When a fuse goes out, first check the instrument panel fuse block. If there are no fuses out, the problem could be in the maxi-fuse block.
The maxi-fuse block outside of the cab on the driver side of the vehicle. To access the maxi-fuse block, remove the four screws from the front of the box and remove the cover.
Power is fed through these fuses to devices such as the headlamp switch, ignition switch feed circuits and the auxiliary brake pump (hydraulic brake vehicles).
Do not use maxi-fuses of higher amperage than those indicated on the maxi-fuse block.
