3 relay mod done! 2 relays for headlight (Lo-Hi), 1 for ignition to avoid burned ignitiion key switch and handle bar controls with crappy switches and thin cables. Now controlling the relays only. All relays have their own 12 V direct from battery, cable fuse close to the battery connection. (Connected at starter solenoid in connection screw)
The relays are connected in parallel to everything else, easy to switch back without relays.
I managed to squeeze in the 2 relays inside the head light!
I think that the coils get better power now when the 12V has only one switch now, the relay. before crappy switch and handle bars switches. I did not measure before, but it must be better now!

EDIT: I have a new tank set with side covers from Yamiya750 with all badges etc. I'm afraid to scratch them so I'll drive the bike a few days in spring until the bike will get the goodies. 1 scratch will be horrible....

The bike project is ready now...
Next project is frame mod kit, open the head cover replacing most of the cyl studs, cam towers and double check o-rings + time the cam again.
