Engine System - Petrol (Gasoline) 204Service Manual – Haram Captor II
Ignition On
• When the main machine controller sees the key switch input, it sends 12v out on the Ignition Request
circuit.
• 12v is provided to the common contact at pin 3 of the high coolant temp. shutdown relay and on through
the normally closed contacts to the fuel pump.
• Ignition power is fed to the low oil pressure shut down relay energizing the relay
– Since there is no oil pressure, the oil pressure switch is closed causing the relay to be energized. This
prevents power from being passed to the “engine run” input into the main machine controller.
• 12v passes through the fuel select connector from pin 3 to 1 via the gasoline plug connector to the ignition
request relay coil.
• 12v is provided to the actuator pin 1, which wakes it up.
– The actuator provides a switched path from pin 9 to 5. This provides a ground for the ignition request
relay turning it on.
– The ignition request relay passes battery power to the ignition system, carburetor fuel shut off solenoid
and the low oil pressure shutdown relay common contact at pin 3.
– Solenoid.
