With Hitachi Distributor

Hitachi Igniter Unit Test
1. Remove the distributor cap from the housing.

2. Disconnect the wires from the igniter unit. Check voltage between the Bu wire and body ground, then the BI/Y wire and body ground, with the ignition switch ON.

There should be battery voltage.

3. With the wires disconnected, check for continuity in both directions between A and B terminals. (RX100 scale)

There should be continuity in only one direction.
