Coil - MOTO GUZZI V7 E5 Special-Stone Service Station Manual

V7 E5 Special-Stone
•
Circuit interruption.
Troubleshooting
Short-circuit to positive:
•
Disconnect the injection loads relay (No. 28 on the electrical circuit diagram), turn the key
to the ON position and activate the injection loads relay through the diagnostic tool.
•
Verify the presence of voltage between injection loads relay connector PIN 1 and 2 toward
the wiring harness.
•
If no voltage is read, disconnect the control unit and verify insulation from battery positive
of the injection loads relay PIN 1 (or control unit PIN 22). If necessary, restore the wiring
harness.
Short-circuit to negative:
•
Disconnect the injection loads relay (No. 28 on the electrical circuit diagram) and the control
unit.
•
Verify ground insulation of the injection loads relay connector PIN 1 and 2 toward the wiring
harness: if there is no insulation, restore the wiring harness.
Open circuit:
•
Disconnect the injection loads relay (No. 28 on the electrical circuit diagram) and the control
unit.
•
Verify continuity of the wiring harness between the injection loads relay and control unit:
Injection loads relay PIN 1 - control unit PIN 22. If necessary, restore the wiring harness.
