If ambient temperature is above 45F (7C) it will be necessary to "hot-wire"
the system in order to actuate the valve.
This is accomplished by
disconnecting the cold start temperature switch from the engine harness and
connecting a jumper wire across terminals of the engine harness connector,
refer to Detail A. When finished, be sure to remove jumper wire and connect
Valve plunger should move up and remain up until ignition switch is released from START position.
If valve plunger does not move up, apply 24 vdc directly to valve electrical connector. If plunger still
does not move up, valve is defective and must be replaced. If plunger moves up, electrical wiring is
Position ignition switch to OFF, place battery disconnect switch to off position, and connect fuel
If jumper wire was used, remove jumper wire and connect electrical connector for temperature switch.
