Faulty regulator rectifier- can't start the bike

Ihave a C90 that had a battery problem. The dealer replaced it and a week later it would not start and they needed to replace the regulator rectifier. After one more week once again the bike would not start and the stator coil need to be replaced. I am concerned that suzuki has faulty parts or that the dealer repair department does not know what they are doing. They have told me that the faulty regulator rectifier caused the battery and stator coils to be damaged resulting in the inability to start the bike. All in I will be out over $1,000 for these repairs that may not stop at this point.

I have a '07 C90T.
I have just replaced my stator. I replaced the reg/rectifier earlier this year. I replaced the battery one year ago in October.

I firmly believe what started the problem. Two guys that I told I didn't need help, but they pressured me to let them help. They hooked a battery backwards to my bike. A lot of people believe that's what shortened the life of the rectifier and stator.

But keep this in mind. The connections for the regulator/rectifier are not waterproof. I had done a lot of rainy riding and I first found a burnt connector on the discharge side of the reg/rect. My mechanic told me I needed to replace the reg/rect so I did but I soldered the wires and made them waterproof. I didn't do this on the stator side of the reg/rect and a few months later, when the bike quit charging again, I found that connector burnt, so I cut it out and soldered and waterproofed it.

Two days after we got back from a 700 mile round trip to Red River, NM, my bike quit charging again. This time though, I have a voltage meter on the bike, so I was aware of the problem before the bike could strand me someplace. Get one of those btw.
When I checked the old stator after I replaced it, I found the stator good but the pulse signal generator bad. It's required that you replace both btw. You have to, they are joined at the grommet.

Ok well, the battery cost $60 last year and I replaced it myself.
The reg/rect cost $140 through my mechanic and I replaced it myself.
Got the stator online for $173 shipped and they advertise a better stator that puts out 20% more power.
Not counting little things like solder, tape, heatshrink and such, I'm out a little less than $375 on my charging system.
I hope it's a done deal.
Again, some think the problems began when the battery was hooked up wrong, but I lean to believe the sub-standard Suzuki connections may have a hand in this.
Hope this helps. . . Joe

Hi I have a aprilla sport city 125 the problem is that while the Bick is running the battery does not charge

Its better u take it to a motorcycle service, they can check the voltage that the scooter produces to charge the battery, maybe its the regulator or the magnetic field.

Yes, you need to check your charging system. First remove the battery and fully charge it (overnight) then refit, and start the bike. With the engine running at about twice the idle speed check the voltage at the battery. It should be approx 14 volts DC. If it is lower than 12.5 you should look first at the voltage regulator and rectifier. The symptoms you describe lead me to believe your charging system is the culprit. It may also be be your alternator, but check the regulator and rectifier first (cheaper)

Brand new batterys keep dieing and bike cuts off 10 sec aftrer starting

sounds like you have a faulty rectifier/regulator.When these items fail it usually causes the battery to go flat or boil.See your dealer for parts.

I have a 2006 C90T and had the exact same issues. I have no great solution for you other than to tell you that in my case it turned out to by the stator. This is one of the only known reliability issues with this bike. With the regulator and stator setup on the standard C90 the stator is basically 'running' all the time due to the type of regulator/rectifier. What myself and many other have done is to replcae the regulator with Cycle Electric CE602 (made for Dynaglide Harley). This type reduces the load to the stator hopefully extending the life of the stator. The CE602 is much larger than the stock one and will have to be relocated. All my power issue went away once upgrading to a better charging system. To be sure though I would get it into a shop to have them test it right.

the stator is behind the front cover on KS side, must drain oil and will need new gasket, normally when it burns out it takes the rectifier/regulator with it!!

Recommend Ricks Stators on line this is a better replace ment than OEM, mine has lasted 2 1/2 years so far (this was third replacement) Also recommend relocating the regulator to the bottom front of the battery box (requires fab a plate and extending wires and solder connections) this allows it to get more air and stay cooler I also added additional grounds

sounds like the problem is your battery is not charging when you are riding. The most common cause is a faulty regulator / rectifier. Contact a motorcycle wreckers for these parts, or your yamaha dealer.
Easy way to test is, when your bike is running, and the lights start to dim, before the bike shuts down, using a volt meter, test the voltage at the battery terminals, should be about 14V. If faulty rectifier,no charge going in to your battery, then the reading will be low, about only a few volts. If you dont have a volt meter, then any mechanic shop can do this test for you. best to have this done before buying any parts.

hi this might help,normally if the alternator/generater fails you will get no charge voltage at all,if your bike is fitted with an alternator(most later honda models are)then you will have a rectifier and regulator,the rectifier converts the ac voltage from the alternator to dc voltage which is then fed through the regulator and then onto the battery,if the bike is fitted with a generator then you will still have a regulator but no rectifier,a generator develops dc voltage at its source so a rectifier is not needed,a simple way to test the system is with a simple digital volt meter,these are very cheap and reliable and can be got for around 20 bucks,with the engine running at about 1500 -2000rpm test the voltage across the battery with the meter normall voltage at charge should be between 13.8 and 14.8 volts,if you are getting more that this then the regulator is faulty,another way to test the regulator is to slowly lift the engine rpm from idle through to about 3 or 4000rpm the voltage across the battery should not rise any higher than about 14.2-14.8 and it should reach its peak at about 2-2500rpm and not fluctuate more than about 1 volt across the rev range,if the voltage exceeds about 14.8 or fluctuates excessively with engine revs then the regulator needs to be replaced.hope this helps...cheers ian
