It has five unmarked leads/wires out.

I emailed the seller, he said that he would send the correct one and I'll send him back this one. I am a little leery of this guy though, what with ebay being ebay and all, but we'll see. I've still got jetting issues (and muffler issues! oh, and I need a new oil drain pan as that drain screw is stripped out) so I can keep working while I wait.
I had previously bought one off a kawasaki 700 atv, but it failed the diode test. ....of course, I didn't think to test it BEFORE i put it on

And, I'm sure you'll like the other RR much better, not only will it handle the charging duties better, especially if you add any amount of accessories later, it will dissipate the heat better as well, and that translates into longer life and less worries. Be sure to wire it right, any questions on that, drop me a pm when you get it, there's also plenty of tutorials, but sometimes it's just nice to talk to someone.
I hope this replacement works well, as I said before I have two other R/R's on there (including stock) and neither worked. According to the stator papers' test, the stator is good so I don't know what else would cause an R/R to blow (if it is me causing it and not just me buying faulty parts). I think the stator papers also failed me on "good r/r connection to battery positive" but my r/r was bad and the papers check the wiring before the r/r so I don't know. I also had the r/r wired directly to battery positive with a 20amp fuse if that matters.

Ok, I want to discuss R/R's a little bit and the theory behind them and then what our bikes need.
At first glance, I thought *all* R/R's would be adequate. Get three-phase AC in, output 14v (or so) to the battery. Well, that isn't the case. It looks like there are single-phase R/R's and 6v R/R's (this is stated on the first page).
BUT! there will always be extreme cases like these, so we can't say "all" but perhaps "most?"
In *most* modern bikes, you'll have three-phase AC power to an R/R that charges a 12v battery. My next question was, why do we give some the thumbs up and others we don't? Current. Our bikes need an R/R that can support enough current. Old_skool mentions that the OEM R/R is 18amp, so it looks like we can boil down our R/R requirements to these three points:
1) Three-phase AC power (it has three input wires for a stator)
2) 12v DC output to battery
3) Rated to handle 18+ amps (I'd guess most modern bikes with a similar amount of electronics would meet this)
Please correct me if I am grossly overlooking something. Checking the approved R/R lists (and there are multiple, this one here and the one through basscliff's site) makes it seems like there are only a handful that will work, but I can't see why a lot of others wouldn't work (bolt-on replacement/spacing aside).
Thoughts? Should I be taking these "approved R/R" lists more of as "known tested/good R/Rs" rather than "these are the only R/Rs that will work?"

got a question about my newtome RR.
its a SH232 6 wire unit. from my readings, the green wire is ground and black wire is "sense" wire. how important is it to attach the sense wire to switched power?
I did a test run of the RR and i did not wire the sense wire yet. when idling, it reads 13.5v
when reving higher than idle, the volts jump up to 15-16v @ around 4k rpm. headlight and parking light gets brighter considerably
i believe this is a bad thing right?
is it because my sense wire is not wired up yet? or is it a bad RR?
ps. my stator is brand new

Connect the sense wire. Without it, there is no sense to the question.

What about SH238-12 1.1?
My rectifier is dying a slow death and I've been looking for a replacement.
I have been looking around the forums for a couple hours now and the only reference to this r/r is in this thread. I cannot find the specs for it on-line either.
There is one for sale on ebay, but I am not sure if it is a suitable replacement.
Any help would be greatly appreciated.
Thanks!
Peter
