The first photo is the Z1 electrical wiring. The second one is the panel under the right side cover. The blue connector comes from the stator and plugs into the blue connector on the panel. The green comes from the voltage regulator. The white comes from the rectifier. The brown comes from the wiring harness. The third one is the stator wiring and the fourth is the voltage regulator.
The blue connector from the stator should have two wires coming out of the harness near your shifter lever. One wire (red/white) should go to your neutral switch. The other (blue) should go to your oil pressure switch. The remaining three wires should all be yellow. These provide 3 phase AC power to the rectifier, which converts this to DC. You can check to see if the stator is working correctly by measuring voltage from phase to phase. You will have three readings, 1 to 2, 1 to 3 and 2 to 3. They should be around 45 to 50 volts with the engine at around 4,000 rpm.
The voltage regulator takes the DC power from the rectifier and limits the voltage available for the battery. Its output to the battery should be about 14.5 to 15 volts. There is an excellent video on Youtube of the Z1 electrical system. Well worth watching.
What components do you have on your machine?
Thank you for the detailed info. I should be able to pour over it through the day.
A few things...
I have a Z1B motor on a KZ900 Frame. My connectors are not under the side covers, instead they are all just above the center stand. My battery doesn't sit sideways. It sits facing the engine.
I have two wires coming from the stator - Blue and White/Red. They go from stator to connector then come out from connection plate blue goes to oil switch and I can't really trace white/red but I'm guessing that goes where its supposed to.
The three insulated wires in your blue connector are cut off on mine. I ONLY have two wires in the blue connector.
I DO NOT have a white connector at all.
My green connector has ONLY a brown wire that connects to the regulator rectifier.
I have another set of wires coming from the spot just behind the shifter. It has a green/yellow/and ??? color wire all going to the regulator rectifier combo.
I have one wire, looks like the white/red one, that joins a white wire through a Y connection that ends at the positive battery terminal. I DO have a 20v fuse on that wire.
I have pictures of my components just above.
My biggest questions right now:
Its been mentioned that early z1s had phase wiring coming from the stator. My wires are yellow/green/??? so how do I know if those wires need to be specifically connected to the three yellow on the regulator? I heard mixing them is bad.
I took the bike out again last night because...I'm a glutton for punishment and like pushing the bike home I guess. I checked the battery voltage before starting (12.4) I checked after starting but sitting at idle (12.1) and then I rode around on it for 30 minutes in the neighborhood. No symptoms at all. I checked the voltage when I got home (12.1) If my charging system was not working I'd expect the symptoms to be regular and for the battery to have depleted in the ride. The only thing I did was plug/unplug some wires/jiggle some stuff/ kick it a few times/ tested resistance on the 20v fuse/ and put it back together. I guess the only good news here is that I am getting more comfortable with unplugging and plugging stuff back in.
Side note...when green connector is plugged in (brown wire going to regulator/rectifier) I don't have to press the start button on the ignition. Just turning the killswitch to run starts the bike. I know that's wrong but I don't know why.
