    .16-.24 between orange and black wires
    4.91 between spark plug wires with plug cap removed.
    But need to check peak reading volts first.

    sorry am an ignorant and
    sorry for my english I am french !

    pls more of your time, according to the 1234 on the joined pic how do I proceed for the coil resistance measures ?
    is it 0.16-0.24 ohms btw 1 and 2 and 4.91K ohms btw 1 or 2 (well the positive...) and 3 or 4 ?
    am not on the spot now. will have it check after you answered thanks again
    of course for the CDI output I am not equipped with a peak reading voltmeter or a DVA adapter, i think if I was, I wont ask all those questions ... !
