    Question removed 2nd ground wire & now no power

    hello am I suppose to remove the thin black wire from the battery that goes into the big black box ?

    u guys say it can get hot short out and catch fire ?

    when I removed mine I had no power to the mfd ,

    hooked wire back up it worked ,

    so it looks like I need to keep mine hooked up to run , does that mean my stator ground is no good ?

    will I be ok or do I need to run a fatter wire , ? - do I need to ground it to engine or something else other then the battery ?

    thanks 4 the help !

    You only remove that wire if you have update kit.

    As best I can tell, the original red engine domestic ignitions should also work with the thin black wire to the battery moved to the engine case.

    To check the stator Black wire ground connection; Disconnect the battery and disconnect the thin black wire from both the battery and the battery cable. Now ohm check the stator black wire. Should be zero ohms from electrical box CDI/stator black wires to engine case.

    It does sound like the stator ground connection is not good. Disconnect the battery and disconnect the thin black wire from both the battery and the battery cable. Now ohm check the stator black wire. Should be zero ohms from electrical box black wires to engine case.
    I have removed the ground from circuit board to battery negative terminal on my 900, so far so good, I have an updated ignition.

    The main ground connection for all domestic ignitions is the stator Black wire to the engine case via a stator mounting bolt. On non-updated domestic ignitions that stator Black wire provides ground only for the CDI and the high voltage spark plug secondary coil energy.

    The thin black wire from electrical box to battery turned out to be a liability and safety issue if the heavy black battery cable was not perfect. If the heavy black battery cable is not good, the thin black wire could overheat during cranking and cause an electrical fire.

    The reason the thin black wiring change is done (removed) at the same time as the Ignition Upgrade is that the Update Kit changes the way the Black wire from the CDI links to the ground points inside the electrical box.

    As Casey points out

    ...
    To eliminate the possibility of the small black wire burning while cranking on an original ignition set up, you can move it from the battery post to the engine case.

    I suspect either the stator black wire is not really grounded at the engine, or some other black/ground wire inside the electrical box is missing or nor connected properly.

    Check to make sure there is a ground wire connecting the box halves together.....
