Fuel Solenoid; Troubleshooting - Arctic Cat 700 Diesel ATV 2007 Service Manual

Fuel Solenoid

The fuel solenoid is used in conjunction with the igni-
tion switch to control fuel flow from the lift pump to
the unit injectors. This enables the operator to shut off
the engine quickly using the emergency stop switch or
the ignition switch. To test the fuel solenoid, use the
following procedure.
1. On a suitable multimeter, place the switch in the
DC Volts position; then connect the black tester
lead to a suitable ground and the red tester lead to
the fuel solenoid terminal.

fuse, the ignition switch, or system wiring. If volt-
age is present, replace the fuel solenoid (see Sec-
tion 4).
