fuel shut off solenoid to actuate the shut off lever. Both 12 volt and 24 volt external fuel shut off solenoids are available.
NOTE: Refer to Procedure (5-31), Fuel Shut Off Solenoid Adjustment/Replacement – Bosch P7100, for instructions to
replace and adjust the synch ro-start solenoid.
The synchro-start has a weatherpack connector with 3 wires in it.
Wiring Guidelines:
Refer to the chart below to find the correct gauge size and length of continuous wire for the white (pull-in) wire, which
connects to the solenoid wiring.
NOTE: 14 gauge wire is required for the red (hold-in) wire, which connects to the โ Runโ terminal on the ignition switch.
NOTE: The black (ground) wire must be the same size as the white (pull-in) wire.
