Toro GREENSMASTER 3100 - Manual (Page 120)

Battery
Terminal Voltage Test
1. Use a volt-ohm meter to measure the voltage be-
tween the battery terminals.
2. If the voltage is less than 12.3 V.D.C., the battery
should be charged.
Hourmeter
Test the hourmeter by disconnecting the wires and
applying 12 V.D.C. between the terminals.
Turf Guardian TM Leak Detector System
Alarm and Delay Timer (Fig. 13)
To test alarm (Item 25)) and delay timer (Item 27), turn
ignition switch to ON, then move leak detector switch
(Item 6) rearward and hold. After a one second time
delay alarm should sound.
Float Switch (Fig. 14)
To test leak detector float switch (Item 3) when con-
nected to circuit, remove hydraulic tank cap and strainer
from neck of tank. Turn ignition switch to ON (DO NOT
start engine). Insert a clean rod or screw driver into tank
neck and gently push down on switch float. Alarm should
sound after a one second time delay.
To test switch when isolated from circuit, disconnect
wiring harness connector at float switch. Connect con-
tinuity tester across wiring terminals of float switch.
Switch should show continuity when float is pushed
down. Switch should show no continuity when float is in
raised position.
Solenoid Valve (Fig. 14)
1. Disconnect wiring connector at solenoid valve
(Item 28).
2. Connect a 12 volt battery so positive (+) battery
terminal is connected to one one lead of connector and
negative (–) is connected to other lead. The valve spool
should retract completely as 12 V.D.C. is applied be-
tween the leads.
3. Iv valve operates smoothly, but does not retract when
12 V.D.C. is applied so solenoid leads, replace solenoid
valve.
