roy-b-boy-b Topic Author Offline User Posts: 3255 Thank you received: 103	I installed the MarkII engine into the "77" KZ and the wiring from the stator is diffrent. The wires coming out of the Mark II are all yellow and the wires coming out of the KZ are sky blue,yellow,and pink. They have a blue connector. How can i wire the yellow wires into the blue connector? Thanks Roy 1979 LTD Street Fighter.1977 KZ1000

Most combo reg/rec's use red or orange as the positive and black or green as ground.

The wires coming out of the Mark II are all yellow I would guess that means those wires are interchangeable elctrically, and I would GUESS they are the AC wires from the generator field winding going to the rectifiers. That's what they are on mine. Don't know about blue, yellow and pink. 1979 KZ-750 Twin

wiredgeorge Offline User Posts: 5310 Thank you received: 44	Roy, I am pretty sure that the blue, pink, yellow scheme is identical to the yellow, yellow, yellow. Get you a cheap Harbor Freight multimeter and check the three legs off the stator to be sure. With the bike running, you should see about 40 VAC on any combo of the legs just like the yellow wired stators. wiredgeorge Motorcycle Carburetors Mico TX www.wgcarbs.com Too many bikes to list!

Fully charge the battery and like WG said, start the bike with the wiring from the stator to the rec/reg disconnected take the engine to 4k.

On my 82 GPZ1100 B2 I get about 50 volts A.C. so watch out about shocks. Get a helper as holding a multimeter to the output plug and reving the engine will be a bit much. You need to measure all three legs of the three phase output.

On the schematics I've seen, some show the 3-phase stator to have yellow, pink, and blue, while others show three yellows. The yellow, pink, and blue was for the older regulators that needed to have the phases in proper sequence for the reg to work properly. If you just use a modern reg/rec, the sequencing won't matter. Just run the three yellows to a modern reg/rec and you should be fine.
