I'm the owner of a Yamaha Diversion XJ600s type 4BR and I have noticed that the voltage when idling is ok little low but acceptable in my opinion, 13.8 volt. When revving to 4.000 rpm or more the voltage is dropping to 12.5 volt with lights on.
I changed the generator (2 others), regulator (3 others), cdi and measured it like all the manuals, but the voltage stays as good as the same with all different parts.
I also placed a new Motobatt battery.
Does anyone have another suggestion or is it sounding familiair?
