Relocating that darn rectifier
Written by pcnz2004 on 2/10/2012 at 07:35 am

I agree with the concept of using the frame as the heatsink and would suggest
retaining the regulator / rectifier in its present location, but would recommend
removing it, coating the back of it with "heat transfer compound" (from your
electronics supply store) a sort of white paste that will actually improve the
heat dissipation to the frame - the mounting position is not exactly flat and
the HTC will take care of these high / low spots.

Relocating that darn rectifier
Hey Yall. Saw an old 2009 post about relocating the rectifier to a cooler spot. Goldwing Fred added thoughts about a thicker gauge wire and then the subject slipped to post reaching smartphones. That's fine, so easily distracted. Oh look. Squ

    How about under the crash bar, right in front of the lower vent opening. Moving it to that location will probably allow you to use the original coil wiring. Just don't steal too much air flow from the stator. Of course the newer MOSFET units

      I'd be worried about water on the R/R with it mounted this low on the bike. I've ridden through some pretty deep puddles and there's no way it stayed dry in there. Tim Davies Seneca Falls, NY Yankee Smuggler II 1998 Sent from

    I've thought that something as simple as a small hose funneling air from the front of the fairing to the rectifier would be just the ticket. But on the other hand, I still have the original rectifier and have had no issues....yet. --- In

      I like that idea. On my 89, I've replaced it twice. Once at about 30,000 and the second time about a year ago at 100,000+. Figure I got my money's worth on the second one. --- In

          Another thought (and I have never had problems with it, so I have not even looked at it). If it mounts flat, maybe raising it up with washers (shims) would allow air flow around it?

    Honda engineered it to use the best heat sink on the bike. (frame) I think the best thing to do with it is to make sure it's in good thermal contact with the frame. On Thu, 09 Feb 2012 20:07:00 -0000 "mrpacrat" <

      I was just kinda stabbing in the dark - have not had a problem with mine yet so I have not really looked closely at it. But I will keep this in mind if I do! > Honda engineered it to use the best heat sink on the bike. (frame) I > t

        You guys are awesome. That's why I love a good discussion. Oh squirrel. OK. Yes Tim, it has to stay dry, very important. I also read about using some tubing to funnel air, and the results were less than stellar. Yes, the frame of the bike

          Every once in a while I find myself starting to think about adding longer cooling fins to the R/R stumpy fins. I even envision making up something out of Silver, the best conductor of heat(and electricity) out of all the metals we know. I kno

        I did just that with my last R/R change. Didn't have it on long enough to tell if it helped. (It's still working, but only has about 7,000 miles on it.) It would be good to have a thermometer bolted to the unit and compare both configurations

    I have a '89 model and I wanted to upgrade the regulator/rectifier AND move it to a cooler location. I had previously used the Shindegen FH012AA unit on my Yamaha XVZ12 with great results. It is modern technology and rated for up to 50 amps.
