    Title says it all. Have an ST 290 with an electrical issue. Any suggestions on Sherco experts in Colorado Springs/Denver etc? Thanks.

    Don't know, exactly, but given all the bikes are about the same, maybe you just need someone generally knowledgeable.

    The experts are here too :-)

    Bill Haskel is in Erie with Balance Trials Supply. Give him a shout.

    I have talked to Bill, and he is suggesting replacing same parts that have already been swapped. Just wondering if anyone out there had true diagnostic skills with Sherco. Thanks much.

    Sherco`s have been known to have some ghost electrical issues. More like poor grounding, then you swap parts and still have poor grounding. We had one down here that went through several owners with everything replaced or rewound. I stayed away from that thing forever. About the third stator and they think it is fixed. Did you buy it this way or what happened?

    Bill runs a business and will fix it if you take it to his shop. For “suggestions” he’s pretty cool and they are free.

    Plus, it's very difficult to diagnose anything over the phone...just speculations and suggestions is all he can offer.

    All above is understood. We talked about the 'ghost" gremlins. Bill seemed to think it was frustrating just trying to get voltage and resistance readings from the Sherco Factory. I was just hoping there might be an old Sherco tech that might know the proper ohms needed across the stator and or coil, etc. I have no problem letting Bill tear his hair out over this one. Thanks for all the responses.

    That is correct, somehow the new Sherco usa website dropped a few old how to video`s. Sherco seems to HIDE any wiring diagrams. Old school Spanish bikes type thinking. We always just did what we could cuz two strokes are easy.:imaposer

    What year, and what do you want to know? I measured a few things when I rebuilt my '14 st3.

    Bill has no hair left, probably from diagnosing ghost Sherco gremmies.

    Wha, too soon?

    Oops... :shog

    Was looking for the resistance across the stator for a "good" one. Same on the coil. It is a 2006 ST 290. Thanks.

    So for a 2014 st3 with Hidria ignition:

    Stator:
    Lighting: yellow - yellow 0.8 ohms
    Pulser: black - white 180 ohms
    Ignition: blue - red 15 ohms

    Ignition coil:
    Primary 1.3 ohms
    Secondary 9.5K ohms

    That is exactly what we needed. I will check the two stators I have. Thanks much.

    Kudos:clap to Luke for providing quality comprehensive tech feedback for resistance readings!

    Such a thing is rare on the Internet.

    Actually no. The splatshop page has them for his correct year and ignition.

    The stators have a number of field coils. The majority are for ignition power and the minority are for lighting and fan power. At least I think so. My `17 Hidria, which may resemble the earlier Hidria seen below.

    An older Sherco with Leonelli or other electrics might have something like following with the hall-effect ignition pulser on the stator plate Upper left) and no bulge in the mag cover on the upper right for a pulser on the outside of the flywheel. The handy thing about the older design is being able to advance or retard ignition timing simply by rotating the stator plate. Stamp a line to record the factory position, then experiment:

    Whatever the brand, I need to poke around and find out how many field coils are dedicated to light and/or fan power, and how many power the ignition.
