8.12 Checking Ignition Module

See Graphic: wc_gr003440

The ignition module (a) is located behind a protective cover mounted

to the machine frame. Battery voltage is sent to the ignition module via

the P wire connected to the R/B wire from the operator presence relay.

To check the voltage at the ignition module, carry out the following

procedure:

8.12.1 Remove the protective cover.

8.12.2 Remove the left side connector (b).

8.12.3 Turn the ignition switch to the ON position.

8.12.4 Check for battery voltage between the P wire and ground.

• If battery voltage is measured, the ignition module is receiving

power.

• If battery voltage is not measured, check the continuity of the wir-

ing between the operator presence relay and the ignition module.

Repair or replace the wiring as needed.

8.12.5 Next, check the continuity of the Br/W wire from the ignition module

(right side connector (c)) to terminal 86 of the fuel relay.

• If the wire has no continuity, replace it.

• If the wire has continuity, see the engine manufacturer’s repair

manual for troubleshooting the ignition module.
