PIN WIRE CIRCUIT FUNCTION
J1-1 85 High temperature shutdown:
Shutdown occurs when Wire 85 is
grounded by contact closure in HTO
J1-2 86 Low oil pressure shutdown: Shutdown
occurs when Wire 86 is grounded by
loss of oil pressure to the LOP
J1-3 13 12 VDC source voltage for the circuit
board
J1-4 18 Ignition Shutdown: Circuit board
action grounds Wire 18 for ignition
shutdown.
