I pulled the schematic off of you site.
I think other years and models did use that color for the reg/rec. The zr400 in the same manual uses that color.
Gotta love previous owners that work on their own bikes haphazardly.
Yes, I do see that. Thanks for posting the diagram. Based on the OP mentioning a white/red wire on the solenoid, which is not shown in the diagram, I was assuming the bike has been partially rewired. I'm under the impression someone took a reg/rec from another model which has the white/red wires and wired it how most Kz's are wired, meaning using the solenoid as the junction for the reg/rec, battery, and possibly main fuse.
That leads to a bigger discussion of how Kawasaki changed the logical location of components and fuses.
Originally Kawasaki used a setup where the output of the rectifier fed directly to the battery (via a terminal on the solenoid) with no intervening fuse. In that setup the main fuse separates the reg/rec/battery from the ignition switch..
Later, Kawasaki started to wire the output of the rectifier so it would directly connect to the ignition switch. In that setup the main fuse separates the reg/rec/ignition switch from the battery.
Originally the main fuse protected the bike from the entire charging system. But the battery and reg/rec were not protected from each other. The later setup only protects the bike from the battery. But it does not protect the bike from the reg/rec. In the later setup, if the main fuse were to break or even blow, while the bike is running on the highway, the bike will most likely keep running but the battery will be disconnected. When the battery becomes disconnected, the regulator loses the ability to regulate properly and you run the risk of over voltage. In my opinion, if the main fuse blows, it should be wired such that it will stop the bike.
So if this bike was rewired, which way was it wired?
