Lucky me, I picked up a beautiful Arctic White 1125 last week. I took it for my first ride yesterday. I came home with smiles. Today battery was dead? I put my battery charger on. I hooked up the charger and I got a spark when I hooked up the power (red) alligator clip? Weird, I took it off turned of the charger and hooked it up, then plugged it in. (probably should have started that way) I get it started, take it for a ride, about 20 miles into my ride the voltage is dropping to 11.7 and the battery light comes on. I make it home and now I am wondering if the PO new about the problem, or did I mess something up installing the battery charger? Where should I go from here? | ||

Check with a meter and see if its charging. Check your stator. These are a known problem. If it has the HD harness fix, the relay may be bad. | ||

Welcome! there is a stator sub forum called'Stator/Voltage Regulator/Charging System subforum' you should read up there, you will find out about stators: 1) from EBR, 2) the harness unfix, and 3) Cycle Electric regulators. 1) http://www.erikbuellracing.com/store/models/1125r/ 2009-2010-charging-system-rotor-modification.html 2) http://www.youtube.com/watch?v=nBYEYGJfyBw&lc=7K_i v4njC--S3_A5mbQwDf83ep5MuHBdSqFNn2lIdzI&feature=in box 3) http://www.badweatherbikers.com/buell/messages/290 431/659737.html p.s. the multi-colored google logo at the top of this page s a good place to start your search. let the learning begin. | ||

I was so close. I tried un doing the harness. When I did this It was at 13 volts! I thought perfect. I took it for a ride. I made it 1 mile, voltage started to drop and the lights came on. Bummer, here I go for my next fix. | ||
| Blacknightrain |
kinda confused about the stator test. Can someone explain it to me? Is the bike running or not? what kind of readings should I get if it is good? I need to get a manual, problem is I just spent all my bucks on the bike, now I need to save for some parts. | ||

Blacknightrain - the last video in Shawns link gives the procedure for stator check. you'll need a multimeter. of course, you're checking it with it installed i assume, and not on you're bench. here's what Froggy said on one of my threads: While you can look at the stator and make a judgment call (burnt ones are discolored, but even healthy ones don't always have a uniform color), the easiest thing to do is take a multimeter and check the AC voltage on all 3 phases to make sure it is within spec. From the electrical manual: quote: 1. Test AC output as follows: a. Disconnect voltage regulator connector [46] from alternator stator wiring. b. See Figure 3-18. Connect an AC voltmeter across stator connector terminals 1-2. c. Run the engine at 3000 RPM. The AC output should be 45-55 Volts AC. d. Repeat the test across terminals 2-3 and 1-3. there's tons of discussion available and can be found using the 'Google' link at the top of the forum page i'll be doing the same procedure soon, just not sure when - (Read: Bubba's a n00b and in a the same boat as you) | ||

Ok, here is what I did. I unhooked the grey deutsch connection to the stator and measured resistance. I got 0.3 between all 3 phases. I started up the bike, I unhooked the same grey connection, I measured between the phases on ac at 3000 rpm. The voltage was 1.5 volts AC on all 3 phases. Did I do the test right? If so it would seem that the stator isn't putting out any voltage. | ||
| Shawns |
That's what it sounds like. | ||
| Blacknightrain |
It just seemed odd since I just got it, but the PO probably didn't disclose it. | ||
| Bubba_ |
i'm in a similar scenario, just not quite as far along - artic white 1125R - PO said "the battery needs frequent charging" - basically, completely stock i've had to charge the battery once. (Lithium) my plan is to upgrade the rotor ASAP haven't tested the stator yet Blacknightrain - You disconnected the plug that connects the stator to the VR? Then started the bike and tested the stator at that connection @ 3000 RPMs? have i got it right? | ||
| Blacknightrain |
Bubba, That's the way I tested it. I have some manuals coming from a fellow member. I plan to pull it apart this week. I wanted to do the rotor upgrade anyway, I just thought I would do it when it started raining for the winter. Guess I will do it a bit earlier. | ||
| Dannybuell |
I live in PDX metro too. Do you have stands? If you need to borrow I have a pit bull rear spool and an asian front triple stand. | ||
| Blacknightrain |
Dan, I don't have the stands. I have a lift that I can strap the bike down on. Do you think that would work? If not, I would love to borrow your stands. I appreciate the offer! Do you have the crank locking tool? I am in need of one of these for my project. Thanks | ||
| Dannybuell |
I don't have a crank locking tool. | ||
| Bubba_ |
i have one i could loan it... if you could cover shipping. and then, ship it back to me of course. i purchased it from and another BWBer a while back cuz knew i'd need it at some point | ||
| Bubba_ |
Just so I'm on the right page ...  is this the correct plug to check w/ multimeter for stator readings? can't i also check ohms resistance here as well? (Message edited by bubba_ on October 13, 2013) | ||
| Nikoff90 |
Yes 1.0 Ohms to .3 Ohms is good also none should show continuity to ground. Not certain that is the correct connector as I am new to the bikes. I thought mine was more forward the bike. | ||
| Blacknightrain |
Bubba, Thanks for the offer. When I get close to needing it I will send you a pm and work out the details. Its odd, I tested my stator phase to phase and got 0.3 ohms. I tested continuity to ground and got nothing to ground. Is it possible that my voltage regulator is bad? Whats an easy way to test it? | ||
| Bubba_ |
0.3 is acceptable I think. 0.1 - 0.3 is acceptable range? I'm not the guy to ask  Then the test for continuity sounded good too.. but maybe someone else will confirm. | ||
| Blacknightrain |
My head is starting to hurt  I am thinking about replacing the stator, rotor and vr and hopefully be done with electrical issues. Just kinda wanted to fix it to get some riding in before the rain is here, and address the rotor and stator this winter. My stator was replaced by HD at 1000 miles, I guess its possible it is out again. But maybe I am over looking the voltage regulator? | ||
| Nikoff90 |
Did you test the AC voltage output of the stator. Check for 45 to 50 volts AC at 3000 rpm. Testing is all in the Electrical Service Manual. Found some good info at the UK Buell Enthusiasts website in the downloads. (Message edited by nikoff90 on October 13, 2013) | ||
| Blacknightrain |
I think I did the testing right, and I didn't get any voltage at 3000 rpm. I have both manuals coming this week to help me diagnose this issue. | ||
| Bubba_ |
well.. remember, the video shows a guy testing ohms on his bench. the buell manual advises testing AC volts. so, you'd have to set the multimeter to AC - probably the '250' setting. and with that set, and RPMs at 3000, you'd expect 45-55 volts output on a good stator on all 3 phases. at least, that's my understanding.. | ||
| Pwillikers |
Did you check the harness relay? | ||
| Bubba_ |
Not certain that is the correct connector as I am new to the bikes. I thought mine was more forward the bike.  the new pic i made shows the connection i had thought was correct to test stator voltage at. But upon further exam - it's actually more forward, as Nikoff had stated... correct? (gawd, i'm dense) (Message edited by bubba_ on October 21, 2013) | ||
| Bubba_ |
well, i went ahead and checked the stator output on the above connector. using a cheap-a$$ multimeter, it was bouncing above 40v on all 3 phases. i had the multimeter set on '50v' and my wife running the throttle.  all 3 phases seemed symmetrical in output. and when riding, battery voltage displayed is typically around 13.6 - 14.2 or so... i think my stator may be ok. when i get ready to install the upgraded rotor, i guess the smell test would be more telling. i'll upgrade the VR as well when money is less tight. here's the cheapy multimeter i used  forgot to mention (Full disclosure) i DID check stator output on what i thought was the correct Deutsch connector. <see above> my readings were messed up and i back tracked and stewed a bit before i figured out i was at the wrong connection. LOL i assume it's the HD harness that's in between there and got me off track... (Message edited by bubba_ on October 21, 2013) | ||

I got my voltage regulator today. Now it is time to tear into the Stator. Bubba are you getting close to starting on your bike? We need to exchange numbers so we can bounce idea's off each other! | ||
| Bubba_ |
sounds good Blacknightrain,,, it'll be some time before i'm ready to go with upgrades. (fingers crossed) i'm not waiting for a failure, i'm just a poor boy. i've even toyed with the idea of drilling holes in the rotor like Hilstrom did to save $$. LOL Pm me anytime if you're ready for the tool.. i'll get it shipped out so you can get to work | ||
| Blacknightrain |
Bubba, Sent you a pm. Tell me about drilling your own hole in the rotor, sounds interesting. Surely there is someone with machining talent that has some info |
