    Ignition issue, no spark.

    Obviously new so I will dispense with that. Picked up a 2000 SLH in really good shape for a steal. Ski ran pretty good when I picked it up other then a low end stalling issue. Serviced carbs to find a screw that was out and laying against a diaphragm. I took the ski to the lake for the weekend and ended up leaving it anchored next to my boat and of course through my own stupidity I had not really checked how well the ski was sealed. Needless to say it took on water over night. It was not a huge amount but enough that the ski squatted when I sat on it. I pumped out the water and it would not start. After some investigation I discovered that I had no spark. I let the ski dry out for a week while I was out of town. Came back, ski started right up no issues. Took it out on the river 5 minutes from my house, again, no issues. The next day drove one hour to a lake, this time, no spark. From this point here are the diagnostics I have attempted. According to the service manual I obtained I have the PVL ignition as it states it on the CDI box. Red Polaris Engine. Tested the Ohms on the plug wires to ground, shows no continuity ( 7500 - 8500 according to manual ) Tested according to the instructions on the stator as follows. Black stator wire to ground 3.5 Ohms ( 0-1 according to manual ) Black stator wire to purple 5.6 Ohms ( 1200 according to manual ) Black stator wire to Grey - no continuity ( 88 or 138 according to manual ). The remaining are supposed to be open. Now I also opened the front housing where the stator is, dry in there, same as the electrical box. I am at a loss here, I have worked on several bikes both 2 and 4 stroke, but this is my first ski, so any help would be greatly appreciated.

    There were basically 2 versions of ignition systems,your reference #'s are for the early (GEN 1 ) version.
    You have the later Gen 3 ignition (same as update ign ) you need to use a 2000 and newer service manual. So far your readings look correct for the gen 3 ign.

    Note; these ignitions need a strong battery with over 10.6 volts while cranking-that would be my first test.

    Yep, start by checking the battery voltage when resting and also when cranking. The polaris ignition systems do not like having a weak battery.

    If the battery is old or weak it's probably best to replace it or at least put the charger on it for a while. Do NOT charge the battery with the jet ski's electronics hooked up. Higher charging voltages can cause issues with the electronics on it.

    Ok, I checked the battery out. 11.92 volts resting, 10.77 while cranking.

    Alright by looking through the link you provided I found the PDF for the newer ignition system and will commence testing in that format tomorrow. I just wonder if I'm not missing something blatantly obvious. I was wondering if the kill switch could have something to with it?

    I am thinking either your battery needs a charge or is marginal at best.

    I agree, start with a fully charged battery and go from there.

    Is the new battery fully charged? I only ask because I bought one not too long ago that was "ready to go" and it wasn't fully charged and needed to be returned.

    How are you checking for spark?
