Groundsmaster 4300--D Page 5 -- 35 Electrical System
Fuses
The fuse block is located behind the control arm access
cover (Fig. 39).
In addition to the fuses in the fuse block, a 2 amp fuse
(F3) is included in the wire harness to protect the logic
power circuit for the TEC controller. This fuse resides in
a fuse holder near the battery (Fig. 41).
Identification and Function
Use Figure 40 to identify each individualfuse and itscor-
rect amperage. Fuses for your Groundsmaster have the
following function:
F1 -- 1 (15 Amp): Protects starter circuit power sup-
ply.
F1 -- 2 (10 Amp): Protects main power supply.
F1 -- 3 (10 Amp): Protects power supply for head-
lights.
F1 -- 4 (10 Amp): Protects power supply for power
point.
F2 -- 1 (7.5 Amp): Protects power supply for TEC
controller outputs.
F2 -- 2 (7.5 Amp): Protects power supply for TEC
controller outputs.
F2 -- 3 (7.5 Amp): Protects power supply for TEC
controller outputs.
F2 -- 4 (15 Amp) (if equipped): Protects power sup-
ply for the optional air ride operator seat.
Testing
Turn ignition switch to the ON position (do not start en-
gine). With the fuse installed in the 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 necessary, remove fuse from the fuse block to check
fuse resistance. Fuse should have continuity between
the fuse terminals.
