Scheme of testing the relay of inclusion of starting spark plugs of the side
1. Use an ohmmeter to check the integrity of the circuit between terminal "C" of the spark plug relay and the mounting bracket ("ground").
2. The resistance on the ohmmeter should be about 3 ohms.
3. Use wires to connect terminal "C" of the spark plug relay to the "+" terminal of the battery, and the relay mounting bracket to the "-" terminal of the battery.
Attention! Before connecting the wires, it is necessary to disconnect the wires from the terminals "B" and "G" of the starting plug relay. Under no circumstances connect the terminals of the wiring harness connector going to the spark plug relay to ground. Pay special attention to the correct connection of wires. Incorrect connection of wires will cause the relay to fail.
4. Check the integrity of the circuit between terminals "B" and "G" of the spark plug relay by first connecting the wire to the negative terminal of the battery, and then disconnecting the wire from the battery.
