Diagnosing Distributor - No Spark Chase

Don't know the exact ohm rating for those but I'd bet Google does.

If you connect a volt meter set at it's lowest AC volts to the two wires and spin the distributor you should see a big variance around the 1 volt reading.
It's not real accurate but it does tell you if the pickup coil is sending a signal for the ignition box.

The distributor pigtail on the harness side when disconnected from the distributor exposes 1 of the metal contacts of the two prong plug.
Touch the exposed pin to ground with your key on and you should get 1 spark per touch to ground.
This tells you the box is probably ok.

Before any of this though I would check the pickup coil gap for approx. .008
They can act like that if the gap gets too big.
