Operation CHARM: Car repair manuals for everyone.

California (Digifant I)

Ignition Coil With Power Stage:





1. Disconnect the high tension coil wire from the ignition coil output terminal (terminal 4).
2. With the ignition "OFF" remove the power stage harness connector.

Digifant I Coil Power Stage:





3. Connect a suitable volt/ohm meter between terminals 1 and 3 of the power stage harness connector.
4. Turn ignition switch "ON".

^ The correct reading should be battery voltage (approx. 12 VDC).

CAUTION: Always turn the ignition switch "OFF" before changing meter ranges, and before disconnecting or connecting the meter probes. Doing so with the ignition switch turned "ON" risks permanent control unit damage.

If not wiring harness may be defective check and repair as necessary.

Digifant I Injector Harness Connector:





5. Turn ignition switch "OFF". Disconnect the multimeter. Disconnect the fuel injector main harness connector near the fuel rail.

Digifant I Coil Testing:





6. Connect an LED test light between terminals 1 and 2 of the power stage harness connector.
7. With the ignition switch crank the engine briefly, then turn ignition switch "OFF".

^ The LED light must flicker.

If the LED test light does not flicker, the Hall sender, the Digifant control unit, or the wiring may be defective.

If the test light does flicker continue.

8. With the ignition "OFF", reconnect the fuel injector main harness connector, coil wire, and the power stage harness connector.

Digifant I Coil Power Stage Connector:





9. Connect a suitable volt/ohm meter between terminals 1 and 15 of the ignition coil.
7. Turn the ignition switch "ON".

^ The voltage at the ignition coil should briefly rise to a least 2 volts, then drop to zero volts after 1 to 2 seconds.

If the correct results are not obtained replace the ignition power stage.
