Cheers for that as always you are spot on!!!. I have just fitted the new 5 pin R6 R/R and WOW what a difference I never noticed before but my instrument lights are now so much brighter as well as my low and high beam. It is a pleasure to ride at night now. It is totally amazing the difference this new Regulator/ Rectifier has made. This swap is a must for people with a honda NC24!!.
Before I had trouble, not all the time but sometimes in starting her up but now a light press on the button and away she goes.............................. it is INCREDIBLE honest!!!................................ I still cant get over the difference!!!

Also the yamaha R/R just bolts into the same space as the Honda R/R with just a little mod and it only took 15 minutes to fit.

Your wiring diagram was bang on the money so thanks so much for all your help! Cheers!.

No worries.

If you look you'll see that the back of the R6 reg is recessed.

You can get a thermal pad for these / or heatsink compound.

I applied this first before bolting it to the frame to aid heat dissipation.
