    Welcome to the Hulk!

    Click here for the Polaris Service Manual, and other useful info.

    Use a multi-meter to confirm that you have more than 10.5 volts (measured at the battery terminals) while the engine is cranking.

    If that isn't the problem, work through some of the checks in the Service Manual for no spark. Let us know what you find.

    Polaris did issue an Ignition Update Kit for that engine, so it is possible the CDI/stator in your machine has failed. When you open the electrical box, tell us what part number is on the CDI module.

    come on, like you've never done that

    go with 447's advise. grab the manual and go through the electrical system. Most likely the CDI or one of the coils on the stator is open.

    Could be water in the stator area shorting it out. Heard many a story of taking the case apart and seeing oily water drain out. Using a water removing fluid like WD40 and having the symptom go away. Then all oyu have to due is find out how the water got in there.

    I think your CDI is the original part number for a 1998 SLH, so you probably will need to purchase and install the update kit, PN 2873022.

    There are several suppliers listed here

    If you are OK with doing the mechanical work of pulling the flywheel off, the rest is easy enough. We can guide you along, if need be.

    One nice thing about the two cylinder Polaris domestic engine is you have more elbow room to work around it, than in front of the three cylinder engines.

    Have a look at the attached files, and read the Service Manual regarding removing the flywheel. Also have a look at the 1999, 2000, or 2001 SLH Service Manual, which may have clearer pictures and diagrams.

    You can also search here for more info on getting the flywheel off. The main thing is to expect a battle, and prepare accordingly. Once you get the flywheel to release from the end of the crank shaft (using a sturdy puller tool), the rest isn't so hard.

    If you want to be really sure, we can walk you through the stator coils tests, but in cases where the update kit has not been installed, often enough that is what you need.

    Polaris issued the Ignition Update Kit to correct reliability problems that were occurring as the machines aged. Your SLH is ten years old...

    I am not sure. 1996 was the very first year for the domestic 2 cylinder engine.

    The Polaris Parts cross reference only shows the Ignition Update Kit part numbers for 1996-1997 SL700, but not the original production part numbers.

    Can you find out if the 1996 SL700 actually has the Update Kit CDI installed?

    If it does, then you can use the parts in your 1998 SLH 700 motor.

    However
    , the Update Kit for the 1996-1997 used a CDI with a less aggressive timing curve. I think it would work OK, but the mid-range power will be less than using the correct update CDI part number.
