In addition to the fuses in the fuse block, a 25 A fuse is included in the engine
wire harness to protect the power circuit to the ECU. This fuse is located near
the ECU (
).
Identification and Function
Refer to
to identify each individual fuse and its correct amperage in
the fuse block. The fuses have the following functions.
The fuse F1 (15 A) protects power supply for the key switch circuits and optional
light kit.
The fuse F2 (10 A) protects the SCM start circuit.
The fuse F3 (10 A) protects the SCM power, hour meter, InfoCenter, and parking
brake sensor.
The fuse F4 (2 A) protects power supply for the SCM logic.
Testing the Fuses
Turn the key switch to the R
UN
position (do not start the engine). With the fuse
installed in the fuse block, use a multimeter to check that 12 VDC exists at both
of the terminal test points on the fuse. If 12 VDC exists at 1 of the fuse test points
but not at the other, the fuse is damaged.
If the fuse removal is necessary, ensure that the key switch is in the O
FF
position
and the key is removed from the key switch. Remove the fuse from the fuse
block and check that the fuse has continuity across the fuse terminals.
