Wiring Stator and R/R

[tnutcher]

I had a burnt out Regulator/rectifier a few months back on my 82 vision.  Replaced it with a new one from Electrosports *SP, if I recall correctly.  Problem is the previous owner axed the plastic connector in favor of soldered connections between the white wires coming from the stator to the R/R.  I assumed that since it ran when I fired it up that either a.) I wired them correctly or b.) it didn't matter which wire went to which.  SO now, my stator crapped out, and looking to order one and I see the connector again and it reminded me about my wiring issue.  Does it matter which white wire goes to which white wire? If it does maybe I fried my stator because of that?  Don't want to do that to the new one so figured I'd ask.  Thanks in advance

Does it matter which white wire goes to which white wire?

:) In a word... No... ;)

[tnutcher]

Thank you for the quick reply.  I'm curious as to why it doesn't matter...

Simple, the stator consists of 3 identical windings being rectified and regulated to 12VDC. It doesn't matter which winding feeds which section of the rectifier, the end result is 12VDC. That is why all the wires are white.

Somebody correct me if I'm wrong, but a bad stator will kill a R/R, won't it?

:) Sometimes this can happen, but not always...

My stator was burnt when I got the bike, bur R/R tested ok. Now have a new Tim Parrott stator and all appears good. The newly fitted voltmeter maintains around 14.4 to 14.7v when running.

That makes sense.  Thanks for the clear up!

Thats a great idea, a volt meter.  Not to hijack my own thread but do you have pictures of the finished look or location?  Interested in volt meter, oil press, or maybe even in. vacuum?  I'm not sure if it would even be worth it but just tossing ideas around...

:) Here is the one I use...

Quick question on output of stator.  I installed the new one and fired up the bike, read 12.7 volts at battery before firing, (had it on a trickle charger the past week) and then once started at a high warm-up idle, I was reading in the 17 volt range, back to idle and it would be around 14 volts but seemed to stay in the range of 15-17 volts at varying throttle positions.  Is this correct?  I thought it should be lower like around 14-15 volts at charging.  Or am I not supposed to read voltage at the battery posts?  Don't want to boil my battery or something

17 volts is too high. Anything over 15 is a problem. Bad R/R or bad connection on the (brown)sensor wire or a bad battery. Narrow it down and fix it.

[tnutcher]

The R/R and battery are both less than 6 months old and with very little use on them, battery full of water and been trickle charged nearly every night so it should be fine.  Where is the sensor wire at and what does it sense?? Thanks

Well for whatever reason, I spliced the brown sensor to the battery positive, and checked voltage and was spot on around 13.6-7 Volts.  Checked the voltage at the brown wire coming into the R/R and it was lower around 12.9 but kept rising until it was around 13.2-3.  Reconnected the brown wire and now I'm right where it should be, 13.6-13.85V at the battery.  Not sure if it was the brown wires poor connection but it seems to be working fine now so thats good.  Thanks

Sounds alot like the brown wire had a high resistance connection.  Going straight to the positive post was/is the way to go.

This is a really good example of when a volt meter would be a good thing to have wired into the system.  I would be a bit Leary of the R/R after your erratic experience, at least for a while until it proves itself stable and reliable.
