Fuses

Fuse Test/Inspection
Examine each fuse for signs of overheating,
discoloration, cracking, or other physical
damage. Replace the fuse if you find damage.
To test a fuse, remove it or isolate it from the
electrical circuit. Do this by removing the fuse
from the truck or by removing all the
connections from one side of the fuse.
Use an ohmmeter set to Rx1 scale and measure
the resistance across the fuse. The resistance
must be less than 1 ohm.
