Fuses - Toro Reelmaster 3550-D Service Manual

Fuses

The fuse blocks are located under the control panel cov-
er on the right side of the machine.
Fuse Identification and Function
Use the fuse decal (Fig.24) and fuse block (Fig. 25) to
identify each individual fuse and its correct amperage.
The fuses have the following function:
F1−1 (2 amp) protects logic power circuit to the TEC
controller.
F1−2 (7.5 amp) protects TEC output power supply for
start relay, fuel stop solenoid, fuel pump, glow relay,
glow plug indicator light and console diagnostic light. If
this fuse is faulty, a fault should be displayed by the dia-
gnostic light on the control panel (see Diagnostic Light
in this chapter).
F1−3 (7.5 amp) protects TEC output power supply for
cutting unit proportional relief valve (PRV), lift/lower en-
able solenoid (S1) and lift/lower solenoid (S2). If this
fuse is faulty, a fault should be displayed by the dia-
gnostic light on the control panel (see Diagnostic Light
in this chapter).
F1−4 (7.5 amp) protects TEC output power supply for
front cutting unit lift solenoid (S3), rear cutting unit lift
solenoid (S4), alternator indicator light and over temper-
ature indicator light. If this fuse is faulty, a fault should be
displayed by the diagnostic light on the control panel
(see Diagnostic Light in this chapter).
F2−1 (15 amp) protects parking brake switch, hour
meter, alternator, low oil pressure light.
F2−2 (10 amp) protects engine starter circuit.
F2−3 (10 amp) protects power point circuit.
F2−4 (10 amp) protects worklight circuit.
Electrical System
Fuse Testing
Remove cover from control panel to access fuse blocks.
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, 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.
