NIPPONDENSO Electronic Ignition System: Testing: Notes

Be sure all connections are correct, as reverse battery polarity within the system will damage the ignitor (ignition control unit).

Do not disconnect battery while engine is running or transistors may be damaged.

If a tachometer is connected to system, connect tachometer positive lead to coil negative terminal.

Be careful when checking systems, as slight variations may occur between models. Connectors and wire colors also may vary from model to model.

Illustrations, although specific to certain models, may not apply totally to all models.

Do not allow water to enter ignitor.
