    MSX 140, Looking for some suggestions ????

    I have a msx140 that ran fine last year. winterized it, sat 6 months, took it out of storage, put a new battery in it. it started up, went to a high idle, and I shut it down right away. now it won't do anything. I found that it blew the main fuse. replaced the fuse, now every time you hit the start button it blows the main fuse. any help with this would be very appreciated.

    Did you happen to install the battery cable connections backwards recently?

    not sure, I got the ski after the owner installed his own battery. he took the battery back out before he brought it to me so that could be a possibility. If so he might have fried the ecm. hoping for a simple fix but don't know.

    Replace the 15 Amp main fuse again, but don't touch the start button.

    Make sure the battery is connected correctly. Put the lanyard in place on the handlebar.

    Find the start solenoid down low in the hull, forward of the battery, and use a screwdriver to manually short the two HEAVY terminals together. This is the two studs with thick red wires connected.

    There will be some sparks, so use a firm hand. What you are doing is by-passing the start solenoid.

    As soon as your firmly short those two heavy studs together, the engine should crank and start.

    If it starts and runs, without blowing the fuse again, then you need to replace the solenoid. Polaris has a newer version that is Brown in color. It is more reliable than the older Black body solenoids.

    Update: There is an even newer Black solenoid that does NOT have the metal bottom plate. It is now a totally sealed all plastic design, in Black. It is even better than the Brown version, which has the metal plate.

    the guy has 5 polaris skis on a trailer in enclosed storage and I had to order a bunch of parts for the other skis as well. thought I would make one trip to the storage when the other parts come in.

    K447, you nailed it on the head. replaced the 15 amp fuse, found a blown 30 amp as well. shorted across the solenoid and boom. replaced old solenoid with a brown seadoo solenoid, which is the same, and it works great. thanks for the advice.

    I thought that solenoid looked familiar! That's the same one I put in my SL a few years ago, $30. A heck of a lot cheaper than a Polaris
