2006 GSXR Stator or Rectifier Problem?

[ILLu510nJason]

i have 2006 gsxr 750...
bike died out on me when i was riding. battery went dead. i put a new battery in and it did the same thing a few days later. im not sure if i should change the stator or rectifier..since both parts arent cheap i was wondering is there way i can test to c if its on or the other that is causing the problem?
thanks in advance

Do a search here on charging problems. Include the words "test" "VRR" and "stator". Without the quotes, of course.

You first need a digital readout volt meter. Cheap at Radioshack, Frys, or Harbor Freight.

Then charger your batter fully with something like a Battery Tender. Then start the bike and hook the meter to the battery. With the engine running at 3 to 4000 rpm, check the voltage at the battery. Report back.

Don't guess and waste time/money on replacement parts you don't need.

Run the voltage tests detailed in numerous other battery/regrect trouble threads and report back with the results.

You either need a Rectifier, have a wire burnt out, or your stator went out.

To test the stator refer to the service manual and check what it says. You can either test the voltage coming from the stator or resistance.

Check rectifier to visible damage make sure it isnt burnt out (common issue with this year Gsxr that rectifiers go out)

If you go on gsxr forums there is a free service manual you can download, it will tell you everything you need to know on troubleshooting the problem.

Ok meter reads 13.0 just sitting. Start up bike meter reads 12.65 rev the motor up and jumps to 12.80 at 4,000 rpm

unplug the 3 wire stator connector and test the AC output between any two wires. Rotate and take 3 different measurements. If theyre the same, replace VRR

Well, the only reason you got 13 volts is because you didn't wait long enough after removing the charger before taking the reading. After the battery stabilizes (after an hour or so off the charger or after shutting off the bike), it shouldn't read any more than 12.8. But that's OK for now. We're going to assume that your batter is OK becauase your charging system isn't. It should be over 14 volts. And 13.6 or so is the bare minimum to even begin putting a charge back into a battery. So, test the stator with the engine running at 2 to 4000 rpm as kgmoto said.

To be more specific, find that connector for the wires that come from the stator and unplug it. You'll find 3 larger size wires, often yellow, that go to the 3 windings in the stator. Set your meter to AC voltage (not DC) and take readings between all three pairs of wires. In other words, label the wires A, B, and C. Then get a reading between A & B, B & C, and A & C. Since it's AC, it doesn't matter which way you hook the meter up. Report back.

I get 0.01 on the wires

 

[mototireguy]

I get 0.01 on the wires

0.01 with what setting on the multimeter, Ohms, VAC or VDC?

Is that reading with the engine running?

Same for all 3 combinations of the output leads from the stator?

VDC and thats with the bike on

 

[kgmoto]

So, test the stator with the engine running at 2 to 4000 rpm

You'll probably get good numbers if you do that, your VRR is likely the problem. Do the test anyway if you have the time, then try to use the recall to have a new rectifier installed.

You can test for resistances of the stator wires. They must have continuity between the three wires from the stator. If there is an open in any of the wires, the stator is bad. This is from my experiences with Honda stators.

VDC and thats with the bike on

OK.......

1. Bike should be running at 3 to 4000 rpm for the stator test. Is that what you mean by "bike on"?

2. Your meter should be set at VAC not VDC.

3. Make sure you're measuring the wires that come from the stator and not the wires that go to the rest of the bike's wiring harness.

4. Read this again: To be more specific, find that connector for the wires that come from the stator and unplug it. You'll find 3 larger size wires, often yellow, that go to the 3 windings in the stator. Set your meter to AC voltage (not DC) and take readings between all three pairs of wires. In other words, label the wires A, B, and C. Then get a reading between A & B, B & C, and A & C. Since it's AC, it doesn't matter which way you hook the meter up.

5. Get all three readings. Report back. Be specific with all details.....voltages, meter settings, rpms, which wires, etc., etc. Details, details, details.

Can anyone tell me how to get to the stator Plug to test it? I know its under the tank but i still cant find it theres a large plastic cover right below i cant seem to take off any help would be great. Thanks
