General Instructions

Computerized Ignition System Testing





Always switch off the ignition when disconnecting/connecting ignition system terminals.





Begin by checking all relevant terminals and connectors before carrying out extensive fault tracing procedures.





Never let spark length exceed 5 mm when checking ignition system circuits or control unit may be damaged.
Consequently, connect spark plug to HT lead and earth plug via engine.





CAUTION: To avoid damaging the connector sleeves DO NOT DISCONNECT CONNECTOR from control unit when checking voltage. The volt-/ohm-meter should be connected directly to the wires.
