    Plug Lead Issues

    With removed metal spark plug connector/resistor, the wire tested should read dead short. Zero Ohms.

    The removed resistor should read.. 1,000 Ohms or so.

    That test just revealed where the issue is.

    The test is sort of a T intersection, as it were.
    One way the wire is the cause. the other way.. the plug resistor connector.

    Good luck man.

    i removed the plug and this showed no change when meter connected, attacjhed another plug, was told it was for an sec/sel although one end does not fit the distributor and this showed a reading of 5.0, so i assume the wires is fine
    do you think i could drive on the 5.0 ohm wire until i receive my new leads
