Hi all,
Need the power of your collective wisdom.
Bike died on me three weeks ago at night on the QEW - all power lost. No issues up to this point. Love this bike! Battery had exhibited one strange behaviour a week earlier going weak and not starting the bike even though the headlight was bright. (I didn't check battery voltage at that time.) I put it on the tender for a few days, and it fired up fine. So took it out for a ride and that's when it died 20 minutes later. Bike went completely dark. Had to have it towed home.
Bought a new battery, installed it and...nothin'. So I pulled the main fuse and it was dead. Replaced that, and it blew on insertion. So now I knew I had a short.
Started reading the forums and the manual and based on how things had gone down for me, figured it was the regulator/rectifier and/or stator. Took me several attempts and many hours to get the regulator off. The wire couplers to the stator and back to the battery were a biatch to get off, but turns out they were fine - not burnt or melted. (Even getting my air cleaner box off was a pain. Love how the manual doesn't say anything about the throttle body clamp screws having torx heads. Had to go out and get a screwdriver mid-troubleshooting.)
So...regulator off, and with it still on the mounting bracket (with the horn) I saw something fishy on the back of it...like a tiny discoloured patch. But, still on the bracket, I did my diode tests and it failed miserably. Then I removed it from the bracket and an area larger than a quarter was turning to dust as I scraped at it with a screwdriver. Wires were visible. Clearly shot.
So now my question. Sorry for the extended back story. I did the resistance test on the three wires of the stator connector and all three pairs' readings were 0.1 ohms. The manual says they should be 0.2 to 1.0 ohms. (My multimeter is new, it's digital, and it reads 0 when the leads are touched together.) Is 0.1 ohms OK, or must it be slightly higher?
I'm going to do the "Generator No-Load Performance" test to check AC voltage at 5,000 rpm next. Supposed to be 65V or higher across same three pairs. Will post results here.
Thanks!
