Component Testing; Ignition Switch - Toro ProForce 44538 Service Manual

Component Testing

For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. unplug the switch connector before doing a
continuity check on switch).

Ignition Switch

The ignition (key) switch used on the ProForce Debris
Blower has three positions (OFF, RUN and START) .
On ProForce blowers with serial numbers below
310000000, the ignition switch is mounted to the engine
blower housing. This switch is shown in Figure 5 and
switch circuits are shown in Figure 6.
ProForce blowers with
310000000 have the ignition switch mounted to the
frame panel above the battery. This switch is shown in
Figure 7 and switch circuits are shown in Figure 8.
Testing
1. Make sure that ignition switch is OFF.
2. To prevent unexpected machine operation, discon-
nect the negative battery cable from the battery terminal
(see Battery Service in the Service and Repairs section
of this chapter). Position disconnected negative cable
away from the negative battery terminal.
3. On blowers with serial numbers below 310000000,
remove engine blower housing to gain access to ignition
switch (see the Kohler Engine Service Manual at the end
of Chapter 3 -- Engine).
4. Unplug wire harness connectors from switch.
5. With the use of a multimeter (ohms setting), test igni-
tion switch by verifying continuity between switch termi-
nals for each switch position.
6. Connect the harness connectors to the switch after
testing.
7. On blowers with serial numbers below 310000000,
install blower housing onto engine (see the Kohler En-
gine Service Manual at the end of Chapter 3 -- Engine).
8. Connect negative battery cable to negative battery
terminal. Tighten nut that secures battery cable from 10
to 15 ft- -lb (14 to 20 N- -m). Make sure that battery cover
is secured.
