Starting System Test; Check Operation Of Interlock Switches - Toro Reelmaster 2000-D Service Manual

Starting System Test

This is an excellent test to use when a "slow crank/no
start" problem is encountered. It will determine if the
problem is due to an electrical open, short, or high resis-
tance in the starter circuit.
NOTE: The battery condition and state of charge must
be checked before testing the starter system.
Tool(s) required: Digital multimeter and/or inductive
Ammeter (AC/DC Current Transducer).
Test instructions: Properly connect the ammeter to the
digital multimeter (refer to manufacturers instructions).

Check Operation of Interlock Switches

CAUTION
Do not disconnect safety switches. They are for
the operator's protection. Check the operation of
the interlock switches daily for proper operation.
Replace any malfunctioning switches before op-
erating the machine.
Reelmaster 2000--D
Set the multimeter to the correct scale. With the key in
the OFF position, place the ammeter pickup around the
main negative (--) battery cable and read the meter prior
to activating the starter system. Adjust the meter to read
zero (if applicable). Crank the engine for at least 3 se-
conds and record the results. Maximum starter system
draw for the RM 2000--D is 140 Amps at 65
If current draw is significantly higher than listed, check
for a shorted condition. If current draw is significantly
lower than listed, check for high resistance.
Interlock switch operation is described in the Traction
Unit Operator's Manual. The Reelmaster 2000--D is
equipped with a Standard Control Module which moni-
tors interlock switch operation. Information on this Mod-
ule is described in the Component Testing of this
Chapter and in the Traction Unit Operator's Manual.
Testing of individual interlock switches is included in the
Component Testing section of this Chapter.
