wiring on my kz 650

17 posts in this topic

ok im working on my first build i need to work out some wiring problems. When I picked up the bike it was missing the regulator/ rectifire. Was wondering is i could wire a one peice unit into the bike if so how should I do it or should i just stay stock? I am also having trouble finding the right wiring diagram for my bike. The bike is a 78 kz 650....any help would be greatly appericated!

Here's a stock one. If it isn't what you need, go to the Electrical Troubleshooting page and at the top there is a category that is titled "Pinned threads", whatever you need should be there somewhere.

Are you planning on strip wiring it? I've got mine wired for charging/ignition/headlight/taillight, and I could draw up a diagram for you if you'd like. Glenn. You should have the single phase permanent magnet rotor, which will have two wires coming off of the stator that will go to the two yellow wires on the reg/rec. The red and black remaining wires from the reg/rec will go to battery positive(red), and battery negative(black). There's your charging system. Next you'll feed the hot from the battery positive to your ignition switch. You'll then feed your headlight, taillight, brake switch, and coils from the switch feed. Also, make sure you run a frame ground and an engine ground from the battery negative. Your points wires will run to the negative poles on your coils. You'll see on the points plate 1-4, and 2-3. Each of these will fire the respective coils. You can decide whether or not you want to split the feed off of the ignition switch so that you can have ignition "on", with out the lights drawing, or feed all off one, depending on your preference, and the type of switch you decide to use. You can also decide if you want to fuse the hot feed from the reg/rec to feed the battery, as well as fuse the lights and ignition on there own fuse. I used a "on-off-on" toggle to switch the high/low beam on my headlight, and brought a ground up from the front of the frame where the original horn had been, so I could keep the wiring run clean to the headlight bucket. Same goes for the ground on the taillight. That's why you'll want to ground the frame from the battery negative, if you want to save clutter on your wiring runs. Good luck, they're great old bikes, and will take an insane amount of torture if you give em' a bit of love. Glenn.

thanks animal,,i would like to see a drawing of what u did..my thoughts as of now was to keep the original wiring,but if i need to ill start over i will,,,what ever it takes...now when i got the bike the regulator was missing,i picked up one,,,the rec that came with it was a three wire one(yellow)...can i not use this one?should i find an all in one unit?because i have two yellow wires and a green one with a red or pink chase,,can you tell me what the green one is?thanks for all your help..

The type of charging system will determine what combo reg/rec you will need. My 78b is a single phase. The stator has two wires, and has a permanent magnet rotor. Some kz's have a three phase setup, which will have three wires coming from the stator. I'm not sure on the wire colors you're talking. I wired mine from scratch, and eliminated everything that wasn't essential. If you have the two wire stator, a reg/rec combo with four wires will work, and if your stator has 3 wires, then you would need a 5 wire reg/rec. You can get universal reg/rec combos.

looking close at the wiring on my new build,,thinking it may be easier to strip wire the bike,, what's your thoughts on this?

If you are only going to run headlight and taillight, then definitely I'd strip wire from scratch. I can't see the posted diagram, but that green/red can be eliminated if you strip wire it. IIRC, that green was for the neutral switch. The reg/rec in your picture is for a 3 phase stator, so no, you won't be able to use it. Your stator is a single phase, so you need a reg/rec that should have 2 yellow wires, and a red and black, for a total of 4 wires coming out of the reg/rec. PM me your phone number and I'll call you. That'll be easier. Glenn.
