This is the wrong thread for this discussion, buuutt...Yes you should unplug your stator and do a resistance check between all three leads and ground. If you have a ground, it's bad. If not check each wire to each other (lead 1 to lead2, lead1 to lead 3, lead 2 to lead 3). There should be a small amount of ohms on each one, 1.2 ohms for example( not sure of exact spec). If that checks out, you can do an AC voltage output test with the bike running and the plug disconnected. Same lead arrangement (l1-l2,l1-l3,l2-l3).Again, I don't have the specs but I'd expect to see maybe 5 to 10 VAC on each one at idle. If that's good then replace your voltage regulator which is the little guy with the fins on it that the stator plugs into. Maybe under the seat somewhere??
