    What is the correct way to test the coil off of my bike and the correct resistance numbers can’t find them for my 71 Z50AK2. Thanks

    I don't have a Z50k2 ignition coil at the moment, but these values should be close.

    Resistance from small black wire with bullet connector: ~1.5-2.5 ohms to frame of coil
    Resistance of large wire for spark plug: ~10k ohms to frame of coil. If you have a resistor type plug cap, add about 5k for this reading.

    About all you can do with it off the bike is test the resistance of each winding.
