I went to NAPA the other day for some parts and went to leave and my S3 wouldn't start. I got it jumped and headed home. Pulled the seat and hooked up my DVOM and showed no output at 4K, just
battery voltage that was down to 12.1V. My trickle charger had it charged to 13.2 this morning so I grabbed the service manual to do some testing and WTF, it has no specs for checking the stator windings or rectifier/regulator.
I had continuity between all 3 yellow stator wires, and no continuity between each wire and ground so I think the stator is ok. Those 3 yellow wires coming out of the R/R I think is the diodes and they show
continuity one way, but not the other to the red output wire. So, I think the regulator circuit is bad. Can someone tell me how that part of the R/R get's checked? Also, I checked BikeBandit.com for the price on a R/R at $300. Please tell me there is a cheaper place to get one if needed

Of course the bike is just 2 months out of warrenty, but I'll stop by the dealer to see if they will help out on this and check on any factory recalls. Thanks for your help.
