Open Circuit Relay Wiring Diagram
1. Open circuit relay (on the right side of the partition) supplies current to the fuel pump and pneumatic valve only when the engine is running or starting. When the engine stops, the circuit is opened by the fuel pump switch located on the air flow meter.
2. When the ignition is switched on, use a voltmeter with test leads check the terminals on the relay wiring and check the 12 volts on the terminals Fp and B. With the manually opened plate of the air flow meter, check for 12 Volts on the terminals Fp and B.
3. Disconnect and ground the high-voltage wire of the ignition coil, then invite the assistant to turn the ignition key to the starting position and check the 12 volts on the Fp, B and STA terminals.
4. Remove the connector from the relay and, using an ohmmeter, check that the resistance between terminals STA and E1 is 15-30 ohms, between terminals B and Fc-80-150 ohms, and between terminals B and Fr - infinity.
