Starter Solenoid (Greensmaster 3300)
The starter solenoid used on Greensmaster 3300 ma-
chinesallowscurrentflow fromthebatterytotheengine
starter motor when energized. This solenoid is ener-
gized by the TEC controller when the ignition switch is
in the START position. The starter solenoid is attached
totheleftsideoftherearframebeneaththehydraulicoil
reservoir (Fig. 63).
Testing
NOTE: Before disconnecting and testing starter sole-
noid,testtheTEC controlleroutputswiththeDiagnostic
Display (see D iagnostic Display in the Troubleshooting
sectionofthischapter).IftheDiagnosticDisplayverifies
that theTEC outputs are functioning correctly, consider
that a problem with the starter solenoid or circuit wiring
may exist. An open or shorted controller output (e.g. a
failedstartersolenoid,anunpluggedconnectororabro-
ken wire) cannot be detected with the Diagnostic Dis-
play. Conversely, if the Diagnostic Display verifies that
the TEC outputs are not functioning correctly, consider
that a problem with controller inputs, controller fuses or
the TEC controller may exist.
1. Park machine on level surface, lower cutting units,
stop engine, apply parking brake and remove key from
ignition switch.
2. Disconnect negative (black) cable from battery and
then disconnect positive (red) cable (see Battery Ser-
vice in the Serviceand Repairs section of this chapter).
3. Note wire locations onstarter solenoid for assembly
purposes.Disconnectcablesandwireharnessconnec-
tors from solenoid.
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5 ohms or less). This resistance is due to the internal
resistanceofthemeter andtestleads.Subtractthis val-
ue from the measured value of the component you are
testing.
4. Apply 12VDC directlyacross thesolenoid coilposts
(steel). The solenoid should click as the solenoid coil is
energized. Make sure resistance across the main con-
tact posts (copper) is less than 1 ohm.
5. Removevoltagefromsolenoidcoilposts(steel).The
solenoid should click as the solenoid coil is de--ener-
gized. Make sure resistance across the main contact
posts (copper) is infinite ohms.
6. Resistance across the solenoid coil posts (steel)
should be approximately 13.5 ohms.
7. Replace starter solenoid if necessary.
8. Connect positive battery cable to one main contact
post on starter solenoid, starter cable to the other main
contactpost andtwo(2)wireharnessconnectors toso-
lenoid posts.
9. Connectbattery cablestobattery. Makesuretocon-
nect positive (red) battery cable first and then connect
negative (black) cable.
