Mow/Lift Switch; Interlock Module - Toro GREENSMASTER 3100 Service Manual

Mow/Lift Switch (Fig. 11)
1. Disconnect the mow/lift switch wire connector and
install a continuity tester or ohm meter between the two
leads of the mow/lift switch.
2. Push down on the lift pedal and release it. There
should be continuity when the mow pedal is disen-
gaged. If there is no continuity, adjust or replace the
switch. (See Mow/Lift Switch Replacement and Adjust-
ment in the Repairs section of this book.)
3. Push down on the mow pedal and release it. There
should not be continuity. If there is continuity, adjust or
replace the mow/lift switch. (See Mow/Lift Switch Re-
placement and Adjustment in the Repairs section of this
book.)
Interlock Module (Fig. 12)
The interlock module (Item 26) senses the condition of
the seat switch, traction switch, and mow/lift switch. The
seat switch must remain CLOSED while the traction
switch or mow/lift switch is OPEN for the ignition system
to operate.
The "closed to operate" requirement of the interlock
module makes sure that the engine will not run if switch
leads are broken or become disconnected.
Because of the solid-state circuitry built into the interlock
module, there is no direct method to test it. The module
may be damaged if an attempt is made to test it with an
electrical test device such as a volt-ohm meter.
