Angry Charging system 07 600 gsxr

Typical bs with a Gsxr.... need some help.

I dropped my bike off at Motorcycles Unlimited to see why it wasn't charging ( thinking it was the stator due to the stator cover being swapped out ). Well Motorcycles Unlimited told me it was the voltage regulator ( RR ). I had one from a buddy so i used it and same issue would start, with a good battery couple starts later its dead bike wont start. So i bought another one BRAND new. Battery charged ready to go, starts up fine runs great, 3rd time i go to start it after riding with a buddy. Not enough juice to start.

Well i did the typical test i found by google and friends. Test the stator with a volt reading, im getting 65ish when revving at 5k. No idea what to do next. Im lost for words.

If anyone has ran in to this issue and had it resolved please help. Thanks so much in advance!

It's typical when the charging system fails on a gsxr you replace both stator and RR. If you don't after a while the connector will melt and then you have to do a further repair. Change the stator man. Its easy

What are your volts reading at idle?

Also beat way test the stator is with a continuity test. Use a fluke type meter. Red connector on any yellow wire black on the engine if it shows open, bad stator.

Battery @ Idle 11.85v
Stator @ Idle 20ACV
Stator @ 5000k RPMs 65-69 ACV

What's the condition of the battery? If the stator is putting out plenty of volts and the RR is new, then I'd suggest checking all the connectors, including the one that goes to the starter relay (solenoid). After the AC voltage from the stator goes to the RR, it's converted to DC and regulated then it's sent to the starter relay (usually through two red wires that are a thicker gauge than the other wires in that plug, then it's sent to the battery via the really thick battery cable. Sometimes, components can work when they're cold and then stop working after they've heated up, so you should perform all of your checks both while it's cold and after it's really hot. Good luck!

Let's start with the easy stuff. At idle take a digital volt meter and read the DC voltage at the battery. It should be above 12.5 volts minimum.
Test it again at 5000 rpm. It should be 13.2 volts minimum.
You say you installed a new regulator/rectifier. Is it oem or aftermarket?
Is it the correct one for your bike?
Did it plug in fully with the stator?
Are your ground and positive cables tight?
Last, load test your battery and make sure it's good. If you bring it by I can do it, no charge.

Idle @ 11.74
5k @ 11.98
Yes NEW, OEM
Yes its the correct one.
Yes fully plugged in
Yes battery connectors are tight
Load test at Auto Zone, says good.

Battery test up above are not in your specs but its off a bike that starts and runs and charges. No issues.

Possible that you have a bad stator that keeps burning out your RR

Ok this is what im thinking,

I think it could be this cheap stator cover that i have put on, not giving it a proper ground. Could this be a issue???

It is just a cover. Sometimes the stator will put out correct voltage unplug, testing but under load or connected it does not put out enough.

Well Motorcycles Unlimited was wrong it was not my regulator so i bought two for no reason....

It was the cheap stator cover im getting the voltage i need at idle and its charging... Save your self some time and money just by the oem stator cover lol... Thanks for the tips.

ok i dont get it. how would a cheap stator cover be the problem? and why on earth would Motorcycles Unlimited even think the stator cover could be the problem?? did you tell them you put a cheap stator cover on there? i know well that i would never even have thought that would be the problem.

Why you so butthurt? I told them I bough one and put it on and that's when the issue happen. So I just troubled shooted dude everything tested like it was suppose to but the battery out put from the connectors. My Gf has the same bike so I went from hers to mine and had extra parts. So I swapped it for n giggles and it solved my issue!
