VOLTAGE REGULATOR MAY HAVE A SHORT IN THE HOTWIRE FROM THE RECTIFIRER TO THE BATTERY HOPE THIS HELPS

SOURCE: Faulty regulator rectifier- can't start the bike

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

What I learned on my '07 C90T----- is if it doesn't charge, it doesn't run for long.
I bet it's the battery.

I've had charging problems and I do blame a portion of it on Suzuki's connectors at the regulator/rectifier not being weatherproof.

I had to replace my battery at less than 10000 miles.
I had to replace the regulator/rectifier last April.
I had to replace the stator just two weeks ago.
When troubleshooting, I disconnected the stator at the reg/rect and only got 40 volts at high rpm.
It's supposed to put out 80 volts.
Got the stator from regulatorrectifier.com for half what the Suzuki shop wanted. Paid $173 shipped.

SOURCE: no charge happening on my 2007 boulevard c90 seems

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

What is the stator on a motorcycle


The stator is the alternator as you would know it on a car. It is part of the charging system which consists of the battery, stator and a voltage regulator/rectifier.

Alternating current is generated by the stator and rectified to direct current. The voltage regulator then maintains the voltage to the battery and provides power for additional electrical loads, such as the lights and ignition system, at a constant voltage regardless of variations in engine speed.

Hi iam using bajaj avenger , i just change the battery two time ,but after each month the battry not use , can anyone tell me what may be the problem


there is a stator coil under the cover that charges the battery...usually, wires come out of the stator and then go into an electronic device called a rectifier/regulator...this device rectifies the ac voltage coming from the stator into dc to charge the battery..this device also regulates the voltage to around 13.8 volts so that the battery does not get damaged by overvoltage you get when you rev the engine...the regulator looks like a metal box with heatsink fins on it...if you can obtain a voltmeter. check the battery voltage while the bike is running...you should get a reading of 13.8 - 14.4 volts if the stator and regulator are working..if not, then you will need to determine if the stator coil is bad or if it is just the regulator

I have a 96 Honda CBR900RR and I have redone almost everything on it. I hooked the engine back up and the battery won't stay charged. It will stay charged until everything is running then it cuts off and...


the stator produces ac power which is rectified by the rectifier pack to dc power which is what the electrics uses
the voltage regulator controls the voltage to 14.5-14.8 volts dc
the voltage regulator by controlling the voltage also controls the maximum out put from the stator or the current being produced to charge the battery and run the lights and what ever else you have connected
hot stator and rectifier indicates uncontrolled out put so take it to an accredited bike electrician and have it fixed properly
have the battery load tested as uncontrolled output will boil a battery and ruin it

MTD yard Machine lawnmower,17hp Briggs And Stratton engine. Runs for about 15 or 20 minutes and stalls. It will not start again until I recharge the battery over night. Then only runs again for 15 or 20...


yes it could be

check your battery 1st , then check the stator a/c output

• 10 or 16 Amps DC regulated for charging
battery
• Two black leads (C) from stator
• Yellow connector (D) with two pin
terminals
• Two yellow leads (E) to regulator-rectifier
(F)
• One red lead (B) from regulator-rectifier
to red connector output lead (A)
• 10 and 16 Amp systems use the same
stator, color coding and regulator-rectifier
• Alternator output is determined by the
flywheel alternator magnet size


The stator and regulator-rectifier are the same
for the 10 and 16 Amp systems. The system
output is determined by the flywheel magnet
size.
Test Alternator Output
1. Temporarily disconnect stator wire
harness from the regulator-rectifier.
2. Insert RED test lead (A, Figure 28) into the
V ω receptacle in the meter.
3. Insert BLACK test lead (B) into COM
receptacle.
4. Rotate selector to AC Volts position.
5. Insert RED (A) and BLACK (B) test lead
probes into output terminals (D & E) in
YELLOW connector (C). (Test clip leads
may be attached to either terminal).
6. With the engine running at 3600 rpm, the
output should be no less than:
• 20 volts - 10 Amp System
• 30 volts - 16 Amp System
7. If No or Low output is found, check for
bare wires or other defects. If wiring
defects are not found, replace the stator.
voltage depending on alternator type and magnet size

then check the regulator / rectifier , make sure it is grounded properly

make sure battery earth lead is good

i suspect loss of bat voltage is letting the afterfire solenoid close off the main jet

let me know model and type codes off engine & i will try help further

cheers

My battery wont charge and I just bought it


Hi and welcome to FixYA,

Two possibilities:
  • rectifier / regulator combo (most likely);
  • corroded, burned, loose connection from the stator to the regulator (likely);
  • faulty stator (least likely).
The stator would be producing relatively high AC voltage while revving the bike. The stator output AC voltage are fed to the rectifier / regulator through 3 white wires. Check calls for testiing for the presence of the AC voltage on any pairing of the white wires before and after the connector before the voltage regulator. Check on the regulator calls for checking the battery voltage when revving the bike (14.5 VDC).

Good luck and thank you for asking FixYa.

New battery but still not charging. Is the regulator rectifier built into the alternator and are they servicable


Rectifier should be seperate and normally are about the size of the palm of your hand and have fins like a radiator. From your stator check for A/C voltage coming from your stator. No power = bad stator. If you have power check for bad grounds for rectifier or replace rectifier. 1st thing though is to check your battery cables...

Not geting a charge back 2 my batterie


Hi and welcome to FixYa,

No charge to the battery could be caused by:
  • faulty / loose / corroded / burned terminals / connectors from stator to regulator (most likely);
  • faulty rectifier / regulator combo (likely);
  • faulty stator (least likely).

To determine which, initially visually inspect the wiring and its connectors from the stator to the rectifier/regulator combo. Thereafter, a DVM/VOM is required to measure the AC voltage output of the stator (~30VAC), the DC voltage output of the regulator (~14.5VDC @ 4000RPM) and engine off battery voltage of ~12.5VDC. It maybe to your advantage to have the battery load tested as well.

Good luck and thank you for asking FixYa.

Overcharging battery!?


If it goes over 17 then there is definitely a regulator fault, regardless of what the stator is doing. The very purpose of the regulator (it 'regulates' the voltage within limits) is to NOT allow the output dc voltage to climb when the stator output rises (normal) with increased engine rpm. In other words - by nature of way it works normally, the stator AC output Voltage will rise as the engine rpm increases - it will continue to rise all the way to peak engine rpm. The Rectifier/ regulator with its double-barrel name performs two functions: the first - rectifier - converts the AC output of the Stator to DC volts - if 'UN-regulated' the DC volts would also climb proportionally to engine rpm. But that is where the second function of the Rectifier/Regulator - the Regulator - comes in. The Regulator's job is to stop the voltage rising over a certain threshold even if the stator is trying to drive it higher. It does this by 'shunting' current to ground (short circuit effectively) in a series of pulses; this controlled operation is called regulation. The limit is going to be 15V absolute max and more typically 14.5 or so. If the output rises about this value then it absolutely is NOT regulating. Failures of the regulator where they simply don't regulate and allow full voltage to pass are rare (but not impossible) - much more likely to be short or open circuit, neither or which would give the symptom you have. It still sounds almost like you maybe wired it incorrectly? The stator is inside the left crancase cover - whether or not it has its own problems, have nothing to do with the lack of regulation causing battery volts to go to 17V.
