Fuel Solenoid; Troubleshooting - Arctic Cat 700 DIESEL 2015 Service Manual

Fuel Solenoid

The fuel solenoid is used in conjunction with the ignition
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 proce-
dure.
1. On the multimeter, place the switch in the DC Volts
position; then connect the black tester lead to a suit-
able ground and the red tester lead to the fuel sole-
noid terminal.
