Hi I still have the stock regulator. Looking for an updated link to using an alternative that is as close to plug and play as possible. I know this subject has been beaten to death.

Death +1. http://fzronline.com/wiki/doku.php?id=r ... conversion

Don makes an adapter if you want true plug and play otherwise you will need a few fully insulated female spade connectors.

Also keep in mind that you probably could wire up many 5 wire regulators. The three white wires are universal AC from the stator, the black is ground, the red is positive.

I actually just burned up another one and am gonna try a mostfet...

Also I recommend wiring the negative terminal from the regulator directly to the engine case to ground it and the positive directly to the battery positive.

Thanks for taking the time to respond bones/KC

I saw that thread...rather old. Looking for a solid replacement that is plug and play. i have no problems and don't want to create one trying to fix what isn't broke .....learned that lesson well. But the number of people that have had issues is a lot and ones that "fixed" the issue seem to continue having issues. Seems to me that we would have solved this problem by now with a "drop in replacement". If not I can solder but need to get the right unit. The link showed one unit then the next response was don't use that one .

Bones which one did you burn up?

One that claimed to be stock from ebay.

I connected the regulator directly to the positive of the battery which helped but then measured the voltage drop and it was .5 volts being lost from the regulator to the battery just due to using too small of a wire.
I'm gonna get a mosfet and solder plugs onto the wires and plug it in like that; hopefully with a direct to ground and a larger regulator to battery positive, the new regulator will last longer. I'd bet that the stock wiring harness WILL give you problems at some point if you don't replace it.

I would suggest getting one of those connectors from Don linked above + stock regulator for a plug and play replacement.

And from my experience...buy a regulator from a place that will take returns. You may be buying a 15+ year old product...

This is one of those rare times when you wan to fix something before it breaks. I'd encourage you to consider our advise but ultimately it's your decision. The simplest plug and play option is Don's adapter and an R6 type VR.

The only plug and play solution is the 4 pin old outdated crap VRR that was fitted to 125 bikes. Your bike your cash and your choice, feel free to not fix what IS broke. Mr Yamaha upgraded the VRR in 1995 so yeah it is rather old.

My adaptor is ALMOST plug'n'play. No soldering involved, just bolt the ground wire to the engine cases.

Ok yeah just to be clear the R6 type are also listed as stock for later model years; get that kind of regulator, not the smaller 4 pin kind.

Don nothing is idiot proof.

You should have said

"the additional 5th wire is a dedicated ground which the old crap VRR didn't have, many (experts and I use the phrase lightly) who know the price of everything and the VALUE of nothing well.... Let those fools waste their time and cash. When their TCI gets fried

That thread must have been edited and no note included to verify.I reckon he tried one but it quickly failed.

I do concur the post is confusing.

You require the square finned type but beware some of the cheaper ones ( copies ) are known to be as poor as the originals.
I reckon with r/r's you get what you pay for.

I am looking at these gadgets presently;

I also read the WIKI link, I didn't think it was confusing in the least, but each to their own. That gadget your presently looking at, will work IF your charging rate is out of wack, if however your charging rate is correct 13.6 - 14.4 vdc the gadget is useless. 15.2 volts will slowly kill electrical components, 13.2 volts is too low, the battery will go flat..

Don't take my word for it regarding safe charging rates, read DonTZ125's post here http://www.fzrarchives.com/ipb/index.ph ... opic=60237 that guy knows his stuff.

Thank you guy's for your inputs.
