1986 89 ACCORD AND PRELUDE WITH TOYO DENSO
DISTRIBUTOR

This procedure is not applicable to 1988 89 fuel injected Preludes.

1. Remove the distributor cap, rotor and shield. Remove the distributor hold down bolts and remove the distributor for access. Leave the distributor wiring harness connected.

2. Remove the igniter unit from the distributor housing.

3. With the ignition switch ON, use a voltmeter to check for the presence of battery voltage at the black/yellow wire terminal, then at the terminal for the "BLU V' wire, Battery voltage should be present in both cases.

4. Turn the ignition switch OFF.

5. Measure the resistance between the "BLU 2 and the adjacent green wire terminals. It should be approximately 750 ohms.

The following steps do not pertain to 1989 models.

6. Check the continuity in both directions between terminals A and B of the igniter unit. There should be continuity in only one direction.

7. Connect the ohmmeter positive probe to terminal D of the igniter and the negative probe to ground. The resistance should be approximately 50,000 ohms,

8. If ohmmeter readings are not as specified, replace igniter unit.
