    Got to try to start the "new to me" bike this week-end. It was hard starting, many series of cranking, some backfiring and so on. Reluctantly it started and then I found out there's no lighting power from the alternator. Yes the bike suffered overheating from the P/O .... radiators crushed and empty. And in places the motors external wires sheathing on stator wires and the GPS wire look toasty.
    I pulled the stator and yes, the yellow and white wires are melted off the coils. The six coils look sound, just the wires un-soldered/melted from the coil "tangs". The exciter coil and BLK/RED, RED/WHT wires look ok and measures right, 15 ohm's. The trigger coil, RED & GREEN wires is messed up ...all bubbly and windings separating from the core.
    Maybe that's why the bike backfires? ( Poor trigger timing signal to the ECU)? Looking for a reason for the hard starting and backfiring, I'd feel better if I knew for sure the 100ohm's it's reading is not right.

    So, even if I were to fix the lighting coil by soldering the wires back on, it'll still need a trigger coil. Is it available separatly from the rest of the stator? Anyone have a spare?

    Thanks, Dave

    You have to buy the whole thing. Its not cheap, and it comes with a flywheel, although they might be seperating them out (rumor).

    You can put an 08 unit in there and have more power if needed.

    Wish they used a higher temp solder, or not, maybe this is a Husky way of saving the motor when it overheats. KTM uses a higher temp solder.

    anyway, sorry for the bad news.

    Regardless of the cost bad news, thanks much for the info. Is the 2008 stator a bolt-on? Can reuse my '07 voltage rectifier?

    So, did I use the right terminology for the coils and what-not? (was a bit unsure).

    As for the starting issues, does it sound possible the trigger coils the culprit?

    I see TrailTech does "custom" re-winding of stators for Kawasaki 450's. Wonder if they'd redo a Husky? ( Or if they just do the big lighting coil...not the small trigger's).
