Removed the stator plate and clamp under it today. Shaved a tiny bit of the wire covering NEXT to the trigger sensor and have continuity from there to the 5 prong plug in BOTH WIRES no matter how much you move them….NO break in those wires. Done an OHMS test on the trigger where I bared the wires…same thing started at 14 this time and slowly one point at a time up to 55 then back down to 25 then back up. I looked at the side of the sensor that faces the magnet and it looks as if it has hit the flywheel as it looks to be scraped…. maybe…. and also one arm of the stator coil looks to have hit the flywheel SOMETIME. I did NOT move anything myself AND the owner, who I know, said it HAS NOT BEEN TOUCHED from last year. The mag plate was tight AND the flywheel nut was VERY TIGHT when I removed it. I thought there may be play in the mag plate but NO play in the mag plate when screwed down. I am wondering if something came off and got on that magnet like a screw or piece of metal or something or WHY anything under there would be hitting that flywheel….the coil and the sensor are in PERFECT position relative to the mounting blocks or guides under them perfectly flush with them and ran that way FOR YEARS. Ordered a new sensor. If no one had that flywheel off where did that little scrape come from on the coil laminate and what LOOKS like on the sensor too???
