That one on motorcycelspecs.co.za has a dual disk Fr brake.
The RH disk is kind of obscured in the first pic, but clearly visible in the 2nd. :)
I posted a request for a wiring diagram on another forum. this morning.

Someone on another forum with a ZN700 sent this wiring diagram. It's from the Kawasaki KZ750 Shaft manual.
The 84 ZN700 & ZN750 use the same diagram.

...ZN700-A1 & ZN750-A1 click image &/or open image in new window to enlarge. It's big.


ps: for future reference you might want to edit your signature to say ZN750 Ltd Shaft (non-USA).

another question popped up when i was routing the wiring harness. the voltage regulator has 5 wires, the harness has 6 wires, the intermediate connector has fried wires (just 5, too) hopefully, due to damaged insulation. any way, the brown/white wire isnt connected to the regulator. also, chinese regulators ive found on ebay are having 6 wires. so the question is why mine has just 5 wires? according to the wiring diagram, the brown/white wire goes from the ignition switch to junction box, no idea what it really connects

The brown/white wire to the voltage regulator is the voltage sensing wire that the voltage regulator uses to determine whether or not to charge the battery. My ignition switch has a brown wire instead of brown/white, but it serves the same function.

The 5-wire voltage regulators have the voltage sensing function built into the circuitry, so the brown wire isn't needed.

If you need a replacement voltage regulator, you can probably use one from a Ninja 500 or Vulcan 500 or some other model (credit to loudhvx). Some of the later models from about 2010-on don't have a wiring pigtail on the reg-rec. I installed a good used one from a low mileage 2007 EX500. The connector terminals were reversed, so I cut them off & installed new terminal pins to mate with the wire harness. I also got a new plastic connector from CycleTerminal.com as the old one crumbled.

I don't know. I avoid made in china whenever possible. I'd rather get a good used part that was made in Japan. In addition the the OEM Kawasaki reg-rec I installed mentioned above, I recently installed a good used Honda CBR500 brake master cylinder >> OEM & made in Japan.

ZN700 voltage regulator. From the diagrams at Partzilla the 84 ZN700 voltage regulator doesn't have a wiring pigtail, so a reg-rec from a model without a pigtail might be a good fit for your ZN750. For example the 2010 Ninja 250. The ZN700 probably had the same wire harnesses as the ZN750 & both probably had the same voltage regulator.
