    Thanks For the Info

    Thanks for all the info on CDI and Stator testing. Just fixed a 2000 SLH no Spark problem. I was able to identify the type of CDI and Stator I was working with and trouble shoot My problem efficiently. All-thou I dont exactly know how I fixed it ....I did (think I wiggled the right wire) I was not getting 8v from CDI brn wire

    Spoke to soon? Came in today and sure enough No Spark! First I checked the battery 12v then checked Brown CDI wire 0v... but for some reason after randomly unplugging the red Stator wire I got spark even after I plugged it back in ARRRRRGGGGG. I guess I'm going to check again tomorrow and see if I get the same results

    Battery is never at 12 volts when cranking. Cranking voltage is the only voltage that matters.

    I suspect that your rummaging amongst the wires inside the electrical box may be part of what is happening. Unplugging a certain wire always means jiggling around many others.

    It also means a delay while you work on it, during which time the battery may be able to 'recover' just enough to provide spark while cranking.

    Thanks I agree, I used a battery load tester (Toaster) and got the voltage to come down to below 10v at cdi and still have spark. So its probably a bad connection. However I am wondering if the cdi could be holding the kill circuit closed, I am going to leave my meter hooked to the brown wire and the black yellow unplugged and check in the AM.

    How accurately are you measuring these voltages?

    Is the CDI red/pur plugged in with the other red/pur wires ?
    Or is it routed to the orange terminals ?

    Some of these CDI's had trouble "waking up ". If you unplugged power/ground it would reset.

    @ K477 I am using a Fluke auto range. no decimal point. I think I have ruled out battery voltage as the cause

    @ Casey67 it is plugged into the red/pur group and I guess thats always 12v hot. What wire wakes up the CDI? Grey?

    Correct-the red/pur is always hot.
    The orange is switched on/off when cranking/running.

    Polaris had a TSB to install a jumper wire directly from the red/pur CDI wire to the orange terminals. (all other red/pur need to stay in place for batt power)

    I do not know what wakes it up-it seems more like the CDI just stays in sleep mode-Polaris simply turns on/ off power to the CDI to reset it.

    I don't know what model Fluke multi-meter you are using, but all of mine show DC voltages to two decimal points.

    I usually don't care about the hundredths of a volt precision, but these 'domestic' PVL CDI are sensitive to tenths of a volt whenever the cranking voltage is under about 11.0 volts. At the CDI you need to have at least 10.6 volts and preferably a little more to ensure reliable starting.

    Update, Today I came in and hit the start button and had spark for 1 sec then nothing. Whats funny is nothing was moved or touched, So I checked the cranking voltage it was 12 v static and 10 v cranking... thinking this was the problem I charged the battery with no result. Then I thought maybe I have voltage but not enough Amps, So buy using a test light I discovered that I had a poor/weak connection at the red/pur wire. I could wiggle the red/pur at the circuit breaker and get a different light/tone pulling amps through the test light. I admit this was one of the first things that was mentioned on the trouble shooting guide but I missed it because I trusted my meter reading. So as of now it is working again
