voltage regulator

Postby bubbachicken » Sat Mar 10, 2018 11:13 pm

Guys, I have been looking on eBay lately for yet ANOTHER voltage regulator (the Ricks Motorsports one died yet again), and I came to the thought that perhaps the internal voltage regulation/rectification (LOL) can be achieved by one from another model Honda. I am wondering, there are some there that are as little as 16 bucks, delivered cost in the USA, has anyone tried to check to see if the VRR from a Honda of another vintage or engine size is comparable in function, even if I have to fit it another way? I know that a stickied conversion is posted here, but there is a bit of wiring with that one, and I am thinking that perhaps this is another way we can come to the same trail. Ideas??

btw, one that was listed for the CB650C was also listed for the CBR1000, but another listing for the CBR1000 was super cheap (like 16 bucks or some such), while the one specifically for the cb650c (AND the cbr1000) was $94....

I've never been able to make any sense of the instructions for the stickied one. :(

FolsomL, this is why I am looking at these on eBay. For instance, if the internals of the CBR1000 version are the same as the CB650C version, with only a difference in the terminal ends of wires and the mounting process, heck the Rick's motorsports one (that is supposed to be FOR this CB650C) does not fit original installation location either! I had to alter how it is attached. At that point, I am only paying nearly a hundred for something that STILL is not what it is supposed to be in mounting, but runs on the bike fine. Heck, if I can use the 16 dollar one and it dies once a year without frying my battery early, I am even ok with that. At less than 20 bucks, I can keep 4 on hand and still be ahead of the game, 3 on the bike and one in my parts box! I can even get home with THREE failures on the road!

What I don't know is much about the electrical that is sent between the stator, the VRR, and the battery. I have to assume the charging rate to the battery is the same for each bike. What I don't know is if the current to the VRR from the stator is the same on both bikes. I don't know if running a VRR with different anticipated input voltage and amperages (to the VRR from the stator) is going to harm the stator somehow. I cannot think it would, but I am not in the know on that. Pinhead, do you know? Does anyone know? Since my stator seems to be frying these regulators on a yearly basis anyway, am I even to be concerned about it, and should I just use whatever I can get cheap and go for it, replacing the stator someday? Is the failure due to Ricks using universal internals on their VRR units, thereby doing the same thing I am anticipating doing myself, but at a FAR lower cost to me if I use another of these units? I mean, as long as the lead outputs are the same...???

I crave knowledge! Someone please let me know if I am missing something...

How is your rotor? Of the components of the charging system, the stator is the least likely to fail, but a bad rotor will ruin a new regulator/rectifier.

Have no idea about how well the rotor is working.

I did however note the following...

One VRR is listed as fitting all the below. Now, if that is the case, I hardly find it likely that the CB650C can only use ONE VRR.... The list below is for the SH633-12 reference number, which also is known as
- SH579A-11
- SH572A-12
- SH633-12
- 31600MV4000
- SH638-12
- SH632 / SH633 / SH639
- 31600-KBG-008
- 31600-MV-4-010
- 31600-MY7-305
- 31600-KFG-861

and fits:

- CB-1 (CB400FM) (NC27) 1989-1992
- CB250 1992-2002
- CB400 NC24
- CB400F (NC31)
- CB400SF (NC39)

As for the rotor, how do I check it?

UPDATE

Ok, I am not yet done, but here is an option. It fits this bike, and like I anticipated, several others. It is also almost half the cost of Rick's...

https://www.ebay.com/itm/162922079486

The wiring looks right, but I am still looking for better. For now.

And any info on that stator/rotor checking situation is definitely of value...

Is your bike charging (At least right up until it blows the RR)?

To test the rotor, take a multimeter and set it to ohms. Put one lead on one slip ring and one on the other. You should get a reading somewhere around 4.5 ohms or so. Test it when it is cool and hot. Sometimes it may test ok when it is cold, but it might short out when it gets hot.

Thanks! After I posted that last one, I found a YouTube video showing just this process, on the exact model of my bike (down to the year and color). Mine has prettier highway crash bars, though (because I damaged the factory ones shown on the YouTube example worse than he toasted his :( ).

I am going to take a look this week at this issue, and see what the case is. I recall, somewhere a few years ago, when I in fact did do this test. I have to redo it hot and cold now and see how things are. If I remember, the test passed last time I did it, so it could be that the Rick's VRRs are just good for a year and that is that :evil: . I hope not, for their sake. However, I DID manage to find regulators for 50-something bucks apiece brand new in eBay last night. Multiple units in fact, with the correct wiring and plugs in place.

I also discovered something else, that many of the newer model bike regulators that go for nearly nothing don't have as many wires coming out. Ours has five plus three (if memory serves) but some of those newest units have as few as only five. The three seem to go to the ignition and starter plus ground. Not sure why... :?

Anyway, I have to get to work, but will be back later with additional information that hopefully will be of use to this topic. :)
