How to: up the reliability of your Regulator Rectifier
2 Attachment(s)
This was a pretty simple mod I decided to do in the midst of rebuilding my bike. I know most regulator rectifiers fail because of heat. So I had some leftover silicone paste thats normally used on computer cpus for better cooling and applied that to the back side of the r/r (bought at any best buy or radioshack). The r/r is bolted to an aluminum plate that is bolted to the frame. All sit flush together. The point of the silicone paste is to promote the travel of heat from the r/r to the rest of the bike frame therefore keeping the r/r cooler. Not sure how much it will help but hey its easy and cheap and makes sense (at least to me). Sounds like good insurance to me.
I applied the silicone to the areas marked in red. Attachment 42376 The r/r sits flush with the aluminum plates like so... Attachment 42377 |

i'd grind down to the bare metal on the r/r before sandwiching it on to the aluma plate. |
The r/r you have, has the finned heat-sink, so it's probably also a mosfet-type rectifier.
Those shouldn't give you any trouble. The problem ones had no heat-sink (other than the frame mount) and were the older switching type electronics. You'll probably not have any issues with the one you showed in the pictures. Ern |
regenerated thats a good idea.
maddhattr - i actually only did this write up because i had to replace my r/r because it fails after it heats up. so i got the one off my parts bike and did this extra measure to try to prevent the problem again. either way i see it as an insurance. nothing wrong with making something better right? |
Absolutely not! That's what these forums are all about. Information exchange and tweaking our little beasties.
Thanks for sharing, Ern |
Have you checked the output of the stator as well as checked it for resistance & shorts to ground? Seen people replace RRs when it wasn't actually the problem. As MadHattr059 said, the RR is cooled by the fins. Any extra assurance is a good idea though.

Stators checking good. New battery bout a year ago.

Just thought I would throw that out there. Reg/Rec has 12 checks & the stator has 9.

I wonder if wiring in a thin 12v (for computer use) fan would do any good. Looks like that area is deprived of air flow.

I'm thinking right to the battery with a switch. Any ideas. |
