Make sure you get the Blue exciter wire hooked up correctly
If you don't the alt may not charge or you could have a parasitic drain

Mrclubike, now that makes sense. I know that the negatives are the brown wires grounded. But didn't think that negative wire on the coil changes +-+-!! Thanks for that. Smiley

Yes so I got that black wire from the coil connected to the RPM wire of the gauge. Managed it to work but comes on and off intermittently. Grounding? Gauge fault? I hope I haven't buggered the gauge yet.

Got those blue exciter (D+) connected properly, charging is good. I had that resistor tapped in as well.

Just to make sure, your bike does not have the factory 4-way flashers, does it?
That diode looks like the one that comes with it.  It would have been located in the fuse/relay box under the right-hand side cover.

Thanks Rob. Got this sorted. Yes I have the 4 way flashers.
I also got the RPM working now with the same signal wire except, having to add a capacitor 100nF to the black rpm signal line and grounded resistor 150Kohms tapped after the capacitor to the same rpm signal wire.

If you want some information on the 4-way flasher, I have photos and the installation manual on my hard drive at home.

Neither of them are  easy to understand Shocked
The reason they are so complicated is
They have a latching relay that keeps the flasher going even after the key is turned off but cant be turned on unless the key is on

If you remove this feature they are very basic

Thanks, MrClu.  I got the kit quote a while ago but put it at the bottom of the list of projects.  This post reminded me I still need to install that. 

Thanks for the pics.

Remember that the red cover for the R65 hazard switch is still available from your dealer. And the triangle in the correct way is very nice...
