Hey all,

I just swapped my stator with a Ricks Motorsports model. Rode it today, and when I got to my destination it was dead. I'm getting NOTHING out of the stator. Voltage doesn't increase a lick when it starts.

So where should I look first? Connections were soldered, but I will check those next week when I have time to look at it. Anything else to look at?

Boy this is frustrating.

Thanks,


John

sfair will be able to talk you through it.

He talked me through my problems and I learned alot about the bike! I'm willing to bet that the stator is ok but you should run through the test. My problem was similar to yours but my old stator had also burnt out a main relay (ECU??). Good luck!!

Okay sfair, how do I test the regulator?

Also, my fiancées father is an electrician and he had a $500 fluke brand meter that has just been calibrated. After riding 12 miles the voltage key-on was 12.41, idling was 12.36 with no change (at all) through 5,000 rpm's or so. He suggested battery corrosion so I used sandpaper on the terminals and connections to make sure that was clean. I've got it idling now, gonna let it idle for a while and see if it starts after idling it with the high beams on for a while.

Edit: perhaps worth mentioning, I only had a bad stator on it for a week. Rode in a thunderstorm, next day lights were surging and I was kidding an alien sound from the left side. So, I've read these forums long enough, I ordered a ricks stator the next day and within a week it and a new gasket came in. Swapped them out. Stator was bad, but didn't look nearly as bad as some I've seen pictures of. Not sure if that matters, but there ya go.

First, check the AC output and short to ground of the new stator as a bad regulator can take out a stator, too.
It can be a vicious circle. Whenever one is replaced, the other MUST be checked before the engine is run.
If you have access to an analog meter, it will work better for the reg/rect tests, but a Fluke will do in a pinch.

Post back.

Forgive my newbiness sfair,

HOW do I check the AC? Im an absolute newbie to this. I need step by step :)

Thanks for your time and patience,

John

No problem, but first the lecture. Always troubleshoot a problem to determine the fault rather than just replacing parts. The shotgun method usually results in a wallet that is much lighter and a bike that is not repaired. There are lots of folks here that can help you out with any questions.

Step by step is what you shall receive.

Do you have access to an analog meter? That is prefered.
If not, post back with the make and model # of the meter that you will be using, whether it be digital or analog.

Thanks for the advice!

The stator was definitely bad, it was burnt up. But I should have checked the regulator before running it :mad:

Just out of curiosity (as I'm trying to learn), what is the advantage of an analog meter?

He actually has 3 fluke multimeters (and a handful of other load testers and multi-thousand-volt-thingamajigs that he uses for work). I don't recall seeing an analog one in there. The one I was using was a Fluke 87V.

Thanks for the help!

Quick update;

Rode it home, 41 miles. Ran fine all the way home but towards the end the headlights started to get progressively dimmer. Wouldn't start once I was home.

SO;

I charged the battery to "81%" according to a digital charger my bro in law had. Rode it to my Fiancee's house 12 miles. Then, cleaned the corrosion with sandpaper, and idled it for 30 minutes with high beams on, shut it off, started back up. Then, rode it home 41 miles, finally- dead.

I know you're going to kill me for not testing the regulator first :embarrassed:, but it is what it is and that's what I did. So, I dunno, just bouncing this off of you- doesn't that seem more like (and yes, yes, I will test it) like a regulator, like, it's getting SOME juice but not enough? Seems odd for the battery to last THAT long before it dying, doesn't it? Is it possible to exhibit those symptoms if, say, one or two of those white connections was loose or poorly soldered? I've never had an issue soldering before, I like to think I'm pretty good at, but that's far from me being able to rule out my own incompetence as to why this isn't working :D

REALLY crossing my fingers that it's the regulator and whatever test you tell me to do reveals that. I don't wanna dive into that engine again, drain the oil AGAIN, have to buy more oil AGAIN, etc. etc. Although, I suppose I could re-solder the connections without cracking the inner cover... I dunno.

Thanks sfair. Lemme know!

John

Digital meters work good to measure ohms in a purely resistive setting, but mix in some active and capacitive components and the display can, at times, dance around a bit. An analog meter does not tend to do this.
I will post your first test shortly. You are using the Fluke 87V? (very nice meter)

Yessir. I wouldn't know the difference between that and two leads attached to an automotive light bulb but.. yeah it's nice! Like I said he has three other fluke meters so... he may have another model that can do whatever it is you're needing it to do.

(Crossing my fingers...)

Oh, and is it possible to test the R/R OFF the bike? He's 41 miles away :D I COULD ride out there with whatever is going on going on, but I'd prefer not to. I may have an el-cheap-o meter hiding around here...

I recommend that the bike not move until it is repaired. We will be doing some stator checks to ensure that it is still sound.
If you can beg, buy, borrow, steal a meter, post back with the make and model number.
If you want to buy one, they are available at many places and $30 will get one for your purposes. An audible tone is a nice feature that is worth having on a meter.

Romans, as a veteran of Sfair's testing procedures, I have to say that he is correct about testing first and fixing the problem once the root cause has been determined.... I have a Rick's stator and regulator setting on the shelf in the basement that I bought but ended up not needing, as the problem was not found there.... So, I saved myself a lot of work, and I'm going on 12000 miles since I had my charging problems....but I learned a lot about my engine in the process.... Can't thank Sfair enough for being so patient and providing a on-the-job tutorial....

Sfair,

I have access to a Simpson Model 260. Otherwise that 87V, whichever you think will work better.

Simpson 260...yahoo!!! The gold standard of analog meters.
If you could borrow both, that would be great as the Fluke will be good for voltage readings and the 260 for resistance.
Post back when you have them in hand and we will dive in the deep end.

Is it possible to just use one? These are expensive and he makes a living with them so I don't want to have two of his meters if he gets called in the middle of the night for a job. Another option is maybe to do one of the tests off the bike at his house so I don't have to take the 87V home? Maybe?

Let's just assume I only have the Simpson, will that work?

Give me a few minutes and I'll grab it/find out.
