620 Fuses and relays
Main fuses
The main fuses are located in the main fuse box inside
the battery box on the chassis. The four fuses are
screwed into the fuse box with spring washers and
nuts. It is important that the nuts are tightened to the
correct torque, see table. If they are not tightened
enough, heat can be generated. Too high torque can
cause deformation and cracks.

Normally the fuses last as long as the truck without
blowing. Should a fuse blow, the truck should be taken
in to the workshop for a check of the electrical system.
