Killing Dist pickups ?

Pull the distributor and chuck it up in an electric drill and spin it; you should get around 5VAC. I run Belden shielded wire for the pickup and route it away from as much other wiring as possible. The pins on the adapter may only be crimped and definitely not weather tight.
Polarity is also important. The color changes of wiring don't look right. Violet +, Green - looks reversed from the pickup.
