    00 SLX 1200 Ignition Report Card

    2000 SLX 1200 No Spark. I have done the PVL Ignition tests as per the service manual and everything checked out ok except for a stator test:

    "f. Connect the negative test lead of the ohm meter to the gray (ground) wire coming from the stator and the positive lead to the following wires (one at a time)."

    Specifications:
    Brown - Open (nope, it cycles from Open to 40 M-OHMS every 5 seconds?)
    Red - Open (yep)
    Green - Open (yep)
    Blue - Open (yep)

    ----

    I have some other tests results that seem suspicious that I will also post, but any clues as to what this one means would be greatly appreciated.

    That may just be a function of your particular meter.

    40 Meg-ohms is close enough to infinite ohms (open circuit).

    What is the battery voltage while the engine is cranking?

    What does the Red/Purple wire from the CDI connect to?

    What is the voltage on that CDI Red/Purple wire while cranking?

    If you hold the bilge button down (bilge pump should run), does it have spark while cranking?

    What is the battery voltage while the engine is cranking?
    -- 10.7 V

    What does the Red/Purple wire from the CDI connect to?
    -- Split Red/Purple (did the jumper update and it made no difference in tests, so I put it back to factory)

    What is the voltage on that CDI Red/Purple wire while cranking?
    -- 12.2 Volts

    I also tested the brown wire coming out of the CDI and only got 0.3V while cranking. I am pretty sure I need to replace the CDI, but just wanted to make sure it wasn't something else too.

    That is borderline to no-good. Battery needs charging or replacement.

    I suspect that was not while cranking the engine...

    The CDI may well be dead, but that 10.7 volts from the battery while cranking is borderline.

    It is a new Polaris battery OEM, but I will throw the charger on it again and re-test.

    I also tried a test suggested on a thread by CrazyA where I hooked up a 9V battery directly to the stator brown wire (positive) and engine ground. He said that should give you spark, but it did not make a difference. Not sure about this test though?

    Oh, yes you are right - not while cranking.

    If the main 12 volt battery voltage is too weak, you will not have spark even if everything else is correct.

    Which Brown wire did you connect the 9 volt battery to? The one to the stator, or the one from the CDI?

    Polarity is important; positive terminal of the 9 volt battery connects to the Brown wire going to the stator

    Brown wire inside electrical box going to stator.

    Turns out it was the CDI - thanks for all your help!
