Regulator/Rectifiers. Bring your knowledge

One comment (seeing as how the proper answers have already been posted / just to show what a semi-knowledgeable prick I yam)) is that a very common cause of failure is the plug into the R/R. The connections get loose and/or corrosion builds up (accelerated by some arcing inside the pug), then resistance becomes largish, the plugs overheat, the insulation melts, and this vicious circle becomes more worserer, and everything becomes a charred blackish Blob-o-Doom.
Shindengen is the most common brand fitted to many bikes, and is standard fitment to Honda. The reason mosfet R/Rs aren't commonly fitted is probably to do with price, margins, etc., and the fact Honda has never acknowledged problems with R/Rs. Why should they? They don't generally crap out during the warranty period (so fat Mrkns don't get an itchy lawyer finger), probably have never resulted in a death, so there's no real impetus to change anything.

sweet, well I'll prob buy a mosfet and see how I go at wiring.. might make more of a mess than burnt out reg/rec.
I looked at the plugs and connections they are all still golden/shiny and no corrosion around. A couple of wires did melt the insulation so I replaced those 2 sections.. my reg/rec failure doesnt at first hand seem to have done too much damage. Bike runs fine with reg/rec and stator disconnected. stator checks came back good for now.

sounds ideal/too good to be true haha - why are mosfet reg/recs not fitted from the start. I'll see if I can get my hands on one, a quick search on ebay has returned a kit by Shindengen? sounds chinese.. anyway.

again back to being rather wiring phobic it looks like a bit or re-wiring and modification is needed to fit one.

Yes they are fitted standard on some makes.The shindengen kit on ebay is what yamaha fits as standard.A bit of wiring is needed if you want to upgrade, and maybe a different mounting bracket, but its not that hard if you are confident with wiring, soldering etc.If you buy one, get the kit with the plug connectors.

cheers, look like I will give one a go then. I see the kit with all the plug connectors on ebay, 120 bucks US dollars.. Local bike shop wanted to charge me 270 bucks for an old diode replacement so seems like a safe bet.

Not so confident with wiring due to lack of experience and being color blind - but gotta learn sometime so I guess I'll get some practice installing the reg/rec eh. soldering etc should be fine

cheers for the info

heres a link to how it was done, not your bike but will give you the general idea

Can you distinguish colours at all? There's usually three wires the same colour (yellow) from the stator to the R/R, and the other two are the positive to the battery (red or brown) and the earth/ground (black or green). If you can distinguish these, you'll be fine. As for the soldering, makes sure all the wires are clean, and get plenty of heat onto them so the solder wicks into them well. Buy some heatshrink if you haven't got some: bits for the wires, then a larger size for over the top. If you can keep moisture out, it's all good, as you can otherwise get galvanic corrosion with the wires/solder.

beauty, cheers mate - much appreciated

yellow should be sweet, I know the 3 yellows from stator to reg rec so they will be sweet to work on, red green brown may be an issue but if there is only two it won't be a problem. process of elimination. I should be right

Cheers for the tips on soldering etc too. much appreciated

new regulator installed, managed to get a newer finned type design for better cooling for 80 bucks for now and will buy a MOSFET one in the near future and update how that install goes.

happy riding all
