Electric Reel Drive System (48 Volt Dc) Fuses - Toro Greensmaster TriFlex 3320/3420 Service Manual

Electric Reel Drive System (48 Volt DC) Fuses

Two (2) fuses are used in the electric reel drive system
for circuit protection. These fuses plug into individual
fuse holders and are located under the left side cover
next to the operator seat (Fig. 48).
Fuse Identification and Function
Use Figure 48 to identify the electric reel drive system
fuses.
10 Amp Fuse: Protects logic power supply circuits
for the generator and electric reel motors. NOTE:
The 10 amp fuse holder is a component of the elec-
tric reel wire harness.
60 Amp Maxi Fuse: Protects main 48 VDC power
supply. NOTE: The 60 amp fuse holder wire connec-
tions are attached to the negative (--) terminal on the
forward battery and the junction block next to the bat-
tery pack (Fig. 49).
Fuse Testing
1. Make sure that ignition switch is OFF and key is re-
moved from switch.
2. Disconnect the cutting units from the electrical power
supply by separating the cutting unit power disconnect
couplers (see Opening Electrical Circuit to Cutting Units
in the General Information section of this chapter). This
will prevent unexpected cutting unit operation.
3. Remove left side cover next to operator seat to allow
access to electric reel drive system fuses.
4. Remove fuse from the fuse holder for testing.
5. Fuse should have continuity between fuse terminals.
IMPORTANT: Fuses used in the electric reel drive
system are 58 volt fuses. Make sure that correct
fuses are used if fuse replacement is necessary.
6. Install functional fuse into fuse holder.
7. After fuse testing is complete, install left side cover.
8. Connect the cutting unit power disconnect couplers.
