Interlock Module And Switch; Lighting Coil - Toro Greensmaster Flex 21 Service Manual

Interlock Module and Switch

The interlock module prevents the engine from starting
unless the interlock switch is closed (traction lever in
NEUTRAL). After a safe start, the engine will continue
to run with the interlock switch open (traction lever FOR-
WARD) or closed.
If the engine will not start, perform the following tests to
determine if the interlock module or interlock switch is at
fault.
1. Check that there is a good ground between the inter-
lock module (green wire) and the engine (Fig. 5). Check
all other electrical connections and the interlock module
for damage. Replace any damaged wiring or compo-
nents.
2. Check the adjustment and continuity of the interlock
switch (located on equipment handle).
A. Disconnect interlock switch wire connector from
wiring harness.
B. Place traction lever in the FORWARD position.
The switch should be open (no continuity).
C. Place traction lever in the NEUTRAL position.
The switch should be closed (continuity).
D. Adjust interlock switch until it opens and closes
properly when the traction lever is in the FORWARD
and NEUTRAL positions (See Interlock Switch in the
Service and Repairs section of this Chapter).
E. Reconnect interlock switch to wiring harness.
3. With engine ON/OFF switch in the ON position, at-
tempt to start the engine. If the engine does not start,
check the interlock module using the following steps.
4. Disconnect red wire (male connector) where it con-
nects to the black wire leading to the ignition coil (Fig 5).
A. Attempt to start the engine. The engine should
start.

Lighting Coil

The engine on the Greensmaster Flex 21 is equipped
with a lighting coil to provide electrical current for an op-
tional lighting kit. The coil is located under the engine fly-

B. Ground the red wire (male connector) to the en-
gine block and attempt to start the engine. The en-
gine should not start.
C. Reconnect the red wire to the black wire.
5. Disconnect interlock switch on handle from wiring
harness. Position engine ON/OFF switch to ON.
A. Attempt to start the engine. The engine should
not start.
B. Jumper across the wire harness connector termi-
nals and attempt to start the engine. The engine
should start.
C. Remove jumper and reconnect interlock switch to
wiring harness.
6. Replace interlock module if it fails either of the tests
in step 4 or 5.
