Electric Reel Contactor - Toro Greensmaster TriFlex 3320/3420 Service Manual

Electric Reel Contactor

Greensmaster TriFlex Hybrid machines use the electric
reel contactor to connect the generator, reel motors and
the 48 volt battery pack. The contactor is energized by
the generator controller. The electric reel contactor is lo-
cated under the left side cover next to the operator seat
(Fig. 65).
Testing
1. Park machine on level surface, lower cutting units,
stop engine, apply parking brake and remove key from
ignition 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 contactor.
4. Locate contactor and disconnect all wire harness
electrical connections from contactor. Note wire con-
nector locations on contactor for assembly purposes.
5. Using jumper wires, apply 48 VDC directly across the
contactor coil posts (Fig. 66). The contactor should click
as it is energized. With the contactor coil energized, re-
sistance across the main contact posts should be less
than 1 ohm.
6. Remove voltage from contactor coil posts. The con-
tactor should click as it is de--energized. With the con-
tactor coil de--energized, resistance across the main
contact posts should be infinite ohms.
7. With voltage removed from contactor coil posts,
measure resistance across the coil posts (Fig. 66). The
coil resistance should be approximately 195 ohms.
8. If contactor testing determines that contactor is
faulty, replace contactor.
9. When contactor testing is complete, connect wire
harness electrical connections to contactor.
10.Install left side cover next to operator seat.
11. Connect the cutting unit power disconnect couplers.
