Your regulator/rectifier burn out?

I have heard mix reviews of aftermarket R/Rs. I don't know any company specifics or if Electrosports was even considered when people mentioned them. Most said they weren't worth it and did worse than factory. Again that company can be different.

If it works out for ya then awesome and let us know.

do the GSXR R/R mod, its cheaper and much more worthwhile. test your stator too, I know someone here that had his stator go bad too.

any details?

Test your Stator/Rotor assembly - the (usually yellow) wires, when metered between two of the leads should show some level of AC Voltage (check your repair manual for details on how much and precisely how to at what RPM). There are so many aftermarket R/Rs - I've purchased and used EMGO (generic replacement) on my old EX500 - it ran fine. YMMV...

Just in case you want to understand what's happening on the inside - highly simplified:



This is more likely the case with your bike - a three phase AC stator/rotor combination, and a three phase bridge rectifier:

You mean a resistance test? The resistance is normal across the yellow wires.

[JoshuaTree]

No - you should also have a voltage reading test. Normally, there should be a reading across any two of "N" wires in a rotor/stator alternator setup (i.e. you're reading a two phase delta - like how 240V is generated out of 120V residential service delivery - two phases in 180 degree opposition generate the voltage delta).

With the engine running?
