stator/regulator
So tell me guys, is it true that when a stator goes it usually takes the regulator with it, or am I paying for a misdiagnosis? The stealer told me yesterday that my regulator was burnt out, and now they're putting a stator in it too.

My regulator crapped out a couple months ago and it did not affect the stator. The owners manual will tell you how to test both and it is a pretty easy test that only requires a $10 trouble light. Replacing the regulator is really simple, probably took 30 minutes tops, the part was 100 bucks and definitely not worth paying someone to do. Replacing the stator seams a little more involved since you have to get into the primary and remove the clutch but, I've never had to tackle that one. I would try the regulator first and go from there. Good luck

I got a few more details from the stealer... I sent the bike in to find why my engine/battery lights were coming on and they told me the regulator was shot. So they put a new one on, didn't fix anything, then when I call back they say I need a stator. So, in my nicest voice that I could stomach, I ask why there is a new regulator sitting on my bike. Their reply is that when the stator goes, it almost always ruins the regulator and the bike ends up back in the shop within a week. Since my warranty ran out last month, and I don't need any more bills then I have to, I want to know if they are feeding me bs because they f'd up, or if I really do want to pay for the new regulator that they just went ahead and put on. Someone on here must have had a stator go, did you end up needing a regulator too???

I've replaced stators on two differeent bikes. 2000 Road King and 2002 Road King. Neither one needed a voltage regulator. The 2002 has been running for over five years with no problems. The 2000 about 3 years. In my opinion, they are feeding you a line of BS. They don't want to take the new regulator off and put your old one back on. They have to eat the labor.

You unplug it from regulator and check the ohm resistance of the three wires. OK, then you check the AC around 30-40AC out put from each of the three wires. If it's OK, then it's OK. Regulator changes the AC to 14.9 or so DC There is no way anyone can determine or make a judgement call if it's OK. Need to do it yourself or trust dealer. I do it myself. tells you who I trust. Need electrical diagnostic service manual for exact figures for you system, ohm meter, dc and ac meter. The stator is easy to test. You can do a ball park on regulator but it's actually require special equipment. But if its putting out above voltage and the battery is not cooking it's OK

If the stator somehow had a shorted winding I suppose you could get an AC overage that would fry the coils in the regulator. I'm not an electrical engineer, but I will say that I have never heard that a stator can blow a regulator. I would try checking on the internet to see if this can happen with any type of vehicle in the first place. Dunno... just never heard it before. Definitely heard of needing new regulators OR stators though.
