Fuses
The fuse block is located under the controller cover next
to the operator seat (Fig. 30).
In addition to the fuses in the fuse block, a 60 Amp fuse
is included in the wire harness to protect the power cir-
cuit for the operator cab. This fuseresides ina fuse hold-
er near the fuse block (Fig. 30).
Fuse Identification and Function
UseFigure31toidentifyeachindividualfuseanditscor-
rect amperage in the fuse block. The fuses have the fol-
lowing functions.
FuseA--1(7.5Amp)protects power supply for the out-
puts of the front TEC controller.
FuseA--2(7.5Amp)protects power supply for the out-
puts of the rear TEC controller.
Fuse A--3 (10 Amp) protects turn signal light circuit (if
equipped on models 30602 and 30604).
Fuse A--4 (10 Amp) protects headlight circuit (if
equipped).
FuseB--1(7.5Amp)protects power supply for the out-
puts of the front TEC controller.
FuseB--2(7.5Amp)protects power supply for the out-
puts of the rear TEC controller.
Fuse B--3 (10 Amp)protects power supply to theengine
ECU.
Fuse B--4 ( 10 Amp) protects operator air--ride seat cir-
cuit.
FuseC--1(7.5Amp)protects power supply for the out-
puts of the front TEC controller.
FuseC--2(7.5Amp)protects power supply for the out-
puts of the rear TEC controller.
Fuse C--3 (10 Amp) protects main power supply circuit.
Fuse C--4 (10 Amp) protects power point circuit.
FuseD--1(2Amp)protects logic power circuit t o the
front T EC controller.
FuseD--2(2Amp)protects logic power circuit t o the
rear TEC controller.
FuseD--3(2Amp)protects power supply for the In-
foCenter display.
Fuse D--4 (10 Amp) protects power supply for the horn
(if equipped).
Fuse Testing
Turn ignition switch to the RUN position (do not start en-
gine). With the fuse installed in t he fuse block, use a
multimeter to verify that 12 VDC exists at both of the ter-
minal test points on the fuse. If 12 VDC exists at one of
the fuse test points but not at the other, the fuse is faulty.
If fuse removal is necessary, make sure that ignition
switch is OFF and key is removed from switch. Remove
fuse from fuse block and check that fuse has continuity
across the fuse terminals.
