The regulatory is located behind the left rear frame cover (the one with the gas filler neck in it). You can reach it without taking the panel off up over the wheel but you can't get to the plug. The plug for the stator is located in the same place so you can test both once you take the cover off.

If your stator is bad, these folks can rebuild it. http://ricksmotorsportelectrics.com/partsearch

I had them rebuild one for me. $250 dollars but that is a lot less than a new one from Suzuki.

They also sell a Mosfet style regulator/rectifier but I can't say anything about it one way or another as I didn't buy one from them.

thanks for the reply, gonna check charging voltage today, charged battery last nite, but I suspect something wrong in charging circuit since the scoot runs for about a hour then dies with no juice left in battery to start again, (new battery)

Charge voltage needs to be 13.5v or more to keep the battery charged. If wiring is okay and voltage isn't there rectifier is the most likely problem. How many miles on your 09?

On the 650 13.5 volts won't do it. My charging system was putting out that much and it would not keep the battery up. Spec on the 650 calls for 14 to 15.5 volts at 5000 rpm. At idle I was getting 13.4 volts and at 5000 rpm I was getting 13.8 volts. Regulator tested marginal so I replaced it with another OEM one. Didn't make any difference. I replaced the stator. Now I'm getting 14.3 volts at idle and 14.9 at 5000 rpm.

I should have just replaced the stator in the first place. When I ran the no load AC voltage test on it I was in spec between the two outside pins on the plug. However between the center pin and either outside pin I was getting below spec voltage. Spec calls for 50+ volts AC at 5000 rpm between any two of the three plug pins. When I pulled it out it had one coil that was burned black.

BTW, I had a little over 96,000 miles on it when I started having charging problems.

hey guys, update on charging issue, tested regulator output voltage at battery. initial reading at idle was 13.8 ~14.00, increased rpm and noticed voltage started to increase than dropped to battery volts 12.8~12.9. unpluged stator and checked output on all 3 pins at 3000rpm or so and had constant 42volts ac or so, didn't want to free rev to 5k, stator is ok, unplugged rectifier to check connection, noticed that the male paddle prongs on rectifier side friction fit on female side of connector. I bent the prongs ever so slightly in the direction that would give a tighter fit, repluged and started scoot and monitored. system seems to be working fine after monitored for a while. will check it a couple more times before putting tuperware back on. bottom line is that disconnecting plugs and reconnecting fixed my issue, I hope. scoot only has 1700 mi. on, but wont be the firs time reseating a plug fixes things. anyway thanks for input ,helps a lot

Good deal. Nothing like a no parts needed fix.

hi was it the rectifier, mine is a 2009 too so is there a fault in them as it has only done 8000 miles, and do you have to remove the side panel or can you take under the seat out to get to it

My Admore top case leds have started to flicker. I assumed as did Admore that it was a faulty harness. Replaced harness but it's still not working correctly (actually worse). Adding to that problem, I also purchased an Admore Lightbar which is also exhibiting the same flicker issue. Lights work correctly but once the accelermoter kicks in, the unit goes wonky. Voltage checked the rear running lights which is where both Admore lights (light kit and light bar) are getting power from. Voltage at idle was approx 12.5V but once the engine was revved up, the voltage dropped about 0.5 to 0.75V. A friend of mine who is an installer thinks something is wrong with the voltage supply. Bike keeps charged while riding so I have to assume that the charge level at the battery is well over 12.5V but this matter on the light circuit is of concern . Anyone have any suggestions?

You can check if the charging system is working correctly. Starting with a fully charged battery hook a volt meter to the battery. Start the engine and check the voltage. It should be around 13 volts at idle. Rev the engine to 5000 rpm. Voltage should go to 15+ volts.

I am only familiar with AC LED light fixtures. When they start to strobe it is a bad driver.

In most old Goldwings we just cut the connectors off the three yellow wires and soldiered the wires and wrapped up with a good 3M 88T tape. The two leaving the rectifier most times did not have issues.
