    Welcome

    Well, now you know why we tell folks to just buy and install a strong battery, rather than risking damage by jumping the dead battery.

    Do you now have a strong battery in there?

    What is the battery voltage while cranking the engine?
    Measured with a multi-meter

    What have you done since the reverse polarity jumper pack incident?

    That doesn't sound quite right, unless it is a VERY strong battery.

    Usually the battery voltage before cranking is about 12.5, and drops to 11.x when cranking the engine.

    In any case, the voltage needs to be well over 10.6 volts while cranking, or you will not have spark.

    Open the electrical box, and connect you meter to the Red/Purple wire that goes directly into the CDI module.

    Put the other meter probe on the black wire terminal for the CDI. Check voltage again while cranking.

    Again, the voltage must be over 10.6 volts while cranking, or no spark.

    ok just tested and got 10.7 at the cdi but still very weak spark. is there somthing else like coil or plug wires?

    Try another battery.
    10.7 volts is really marginal.

    You can ohm check the ignition coil ohms, magneto stator ohms and Hall Effect sensors, spark plug wires, grounds, etc.

    But I would start with a stronger battery.

    ya i would do it with a jumper back just hook it up right ,

    place the negative on the engine ground


    usually the breaker would kick in to protect the electronic bits from being fried ,

    Arrow What the Reset button (circuit breaker) does, and doesn't do

    The Reset button circuit breaker does not protect the PWC electronics against over voltage, voltage spikes, or reverse battery polarity.

    It is only there to protect the wiring in the PWC against excess current draw (short circuits) within the electrical system.

    The circuit breaker is primarily there for protection from electrical fire.

    The primary protection for the electronics in the system is the proper practices of the person servicing the machine.

    Abuse the electrical system, and you certainly can damage the CDI and/or LR voltage regulator module. Often without ever tripping the Reset button.

    The 1/4 Amp MFD fuse is the only fuse that has any chance of protecting the MFD against reverse polarity, and sometimes even that doesn't prevent MFD damage.

    There is nothing in the electrical system that attempts to protect the other components from voltage spikes. The electronics are fully exposed to voltage spikes created by outside battery connections, and just have to adsorb and withstand them on their own.

    i put a good hot battery in it and got about 11 and the spark is there but just very weak is the voltage regulator bad?
