8.11 Checking Fuel Relay

See Graphic: wc_gr003439

The fuel relay (a) is located behind a protective cover mounted to the

machine frame. Battery voltage is sent to terminals 30 and 85 of the

fuel relay by the key switch via the pink wires. To check the voltage at

the fuel relay, carry out the following procedure:

8.11.1 Remove the protective cover.

8.11.2 Cut the wire ties that secure the operator presence relay.

8.11.3 Slide the connector down the terminals of the relay so that you can

probe the terminals with the lead of a multimeter.

8.11.4 Turn the ignition switch to the ON position.

8.11.5 Check for battery voltage between terminal 30 and ground.

• If battery voltage is measured, the fuel relay is receiving power.

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

ing between the operator presence relay and the fuel relay.

Repair or replace the wiring as needed.

8.11.6 Next, check if power is being switched through the fuel relay by

checking for battery voltage between terminal 87 of the fuel relay and

ground.

• If battery voltage is measured, the fuel relay is functioning.

• If battery voltage is not measured, the fuel relay is not function-

ing. Check the wiring to and function of the ignition module.
