Help with Charging Diagnosis

[Cbx]

Could some one tell me if I have correctly tried to diagnose my charging fault correctly , I have diode tested the RR as shown on YouTube videos and that's comes back fine , so I've just tried to test the stator side but I have used the three yellow wires that plug into the RR I put my meter to ohms and tested each phases and the meter shows 0.5 ohms on all three.

am I correct in using this plug or is there another one direct from the stator.

Those are the correct yellow wires. These are the book specs.
Generator coil resistance: 0.2 - 0.5 Ohms (Yellow - Yellow) for all three possible combinations.
Infinite resistance (Yellow - Earth)

A further test that may be the most important is the AC voltage at 5000rpm between any two yellow wires needs to be over 75VAC. Again, check all three possible combinations.

The K2 has a more reliable stator than later years because it only outputs 350W instead of 400W. Stator burn out and magnets coming loose from the rotor are the most common charging system problems on the older Vees. I would take the cover off and check for black marks on the stator and uneven rotor magnet spacing if I were you.

Greywolf has most of the test covered but there is another test you can do by checking the continuity on the +red & - black wires on the block connector to the battery,  If the wires are deteriated they can reduce the charge. You can check / bypass these (extra wire needed ) by wiring those wires from the block connector plugged in to the RR direct to the battery to see if the charge increases. You can check them separately or together and if you do have to bypass the loom wires always use an in-line fuse on the live wire .

Cheers chaps, here's the results of todays test . fully charged battery overnight, reconnected battery only,  lights on high starter test, battery dropped to 9.6 volts. 5000 rpm test probes on battery , meter showed 12.3 volts ( no charging or very little I guess ). swapped to AC 200 on the meter probes in yellow wires from stator all showed over 80 @ 5000rpm (not sure what that means ).

Kwackboy need to get some wire to do the test. but to be honest even doing the tests I'm non the wiser.

Really loved this bike and spent a lot of money making how I want it but now feel I shouldn't of bothered Suzuki should be shot for there sub standard work on these models.

Have you tested if the stator has gone to ground ? Unplug the stator from the loom , Set your meter to ohms (2k) put the red probe on any of the 3 yellows and the black probe to a good earth ( battery earth is best) and if your meter goes to 0.00 on any of the 3 yellows it's faulty.
Was there fluctuations in the charge rate bellow 5k rpm ? Or was it stable at 12.3v ? . Generally if the voltage has fluctuations but under the basic charging (around14.4v) rate I tend to go for the RR but if it's stable I start looking at the stator .
On the subject of loose rotor magnets, the last one I did in tests there was charging but very weak , this meaning that with the headlights disconnected there was a full 14.7 volts of charge but the minute you put any load on the stator voltage would drop drastically.

Cheers Kwackboy just done the test red probe in yellow wire black probe to battery negative (I assume that's battery earth) and one of the wires goes to 0 (top left) so is that the stator that's goosed ?

cheers.

If any of the 3 yellows go to 0.00 then yes.

As I wrote earlier, infinite resistance (Yellow - Earth) is required. It appears two of your stator's three phases are shorted to earth.

Thanks blokes, don't know if I can bring myself to spend another £300 + on her might just put a cheap aftermarket one on and get shut know my luck the magnets will fall of next......

thanks again for all the help

If you love your bike then stick with it as you may be buying into more issues on another bike, You can check the magnets when you change the stator.
I'm not sure if they are the same but I think I have a 2008 model stator somewhere at work , you interested if they are the same ?

I can see where your coming from Cbx. A K2 would still get a fair price but not so good as a "Spares or Repair." Is it time for a newer model?
I loved my 2001 FJR but it was time for it to go.
