Fuses

Purpose

Fuses are used in the circuits to limit wiring damage in
the event of excessive current flow. If a fuse fails, look
for a short circuit, a corroded/poor connection, or any
component that appears to have been overheated. A
failed fuse is a sign of a problem in that circuit.

Location

The fuses are located on the right hand side of the lower
frame assembly, above the relays, next to the engine
(Fig. 2049):

How It Works

The fuse block is the point where the wires that carry
12 volts meet the wires that need 12 volts to operate a
component or function. The fuse makes the connection
between the 12 volt wire that needs the current.

Testing

A failed fuse will often be discolored or melted. Please
note that not all fuse failures are easy to see. A fuse
can be checked with a continuity tester if there is doubt.
If there is no continuity between the fuse terminals,
replace the fuse, even if it appears good.
