    on the bigblock kaiser-

    new cap rotor coil module.....

    getting 12v+, good ground.....

    i found out it was cleaned in the parts washer, and i suspect the pickup is the hinky piece....

    the two wires from the pickup give me infinite resistance, my manual is at my parents house so i can't look it up right now, does anyone know how to troubleshoot these units, or know what that pickup resistance should be??

    greg ( gotta get her running for slabby time!! )

    Well, the only two other parts are the pickup and the capacitor, i think you can pick up both for under $25. When i had problems with mine it was the pick up. Can't help with the resistance though. Im one of those replace stuff till you find it guys so i say just replace all the electrical components, but thats just me.

    On the pickup coil:..........
    Resistance from either the white or green leads to GROUND. Should be infinite. replace if not.

    Resistance between the WHITE and <font color=green>GREEN</font color=green> wires should be 500-1500 ohms. Replace if not within this range.

    Also the pickup coil should never be immersed in liquid of any kind.
