a matter of stator?

i have a 77 kz900 a5 motor that seems to have a forign stator/alternator. it has 4 wires comming out of it, one regular sized red with green, one reg red with yellow, one reg black with white and one larger sized wire white with black. it has a larger terminal that is white with flat connectors not round pin like? i need to make this work with my regular loom, has anyone got any ideas? id like to buy a new one but funds have hit rock bottom.

I have four stator websites you can try asking questions on about your mystery stator:

1. www.ricksmotorsportselectrics.com
2. www.rmstator.com
3. www.electrosport.com
4. www.customrewind.com

These guys should be able to help.

thanks but i was kinda hopping that someone could tell me which each wire is for and there location on a standard ststor, ie where is the pink wire located? top left? etc. im going to crack the case and trace the wires inside, i just need a starting point on where the wires are on a standard one,

The wiring from the stator on my 82 GPZ1100 B2 is three yellow 14 or 12 gauge wires (3 phase Alternating Current Wiring) and they connect to the regulator/rectifier which is then connected to the battery and other systems.

This stator sounds custom made and cracking the case to trace the wiring may be the only way to see what's what.

Im getting ready to replace my voltage regulator on my bike. It had a fried regulator and harness on it when I got it. The Bike is a 1981 KZ750 4 Cyl. The yellow wires from the stator had bullett connectors on them with no distinction as to which wire connected which. Does it matter which yellow wire is connected to which yellow wire?I cannot tell which order that it was plugged in before.

Three phase connections make no matter/difference to which goes to what.

yes this leads to my next question, the 3 main wires lead to the jution box, on the wiring diagram they go to to a regulator, mine is all yellow wires ( an aftermarket) does it matter what wire goes to what? they then lead to the rectifier, ha i dont want to sound stupid but im going to anyway because i am when it comes to electrics but whats the difference between a regulator and a recifier?

The regulator controls or regulates(hince the name) the ammount of Direct Current created by the rectifier. This charges the battery and runs the motorcycles systems.

On some bikes both are in the same package and no parts are serviceable as they are sealed with epoxy and must be replaced when either of them fail. On some 650's they are seperate units.

To answer your question... I have NO idea WHY there would be four wires coming off the stator. There should be three wires conveying alternating current to the regulator AND rectifier at the same time. There is a tee connection between the regulator and rectifier. The rectifier bridge converts AC to DC and the regulator controls the amplitude of the DC waveform which is how it controls the voltage level. On a stocker the tee exists so that the regulator and rectifier have a single function. On a combo newer unit (reg/rec), both functions are in the one box. The reg/rec will have three yellow wires which are legs to receive the AC from the stator. it will also have a white, red or white/red wire and that is the DC voltage OUT that is connected to the main battery terminal via a lug on the solenoid and also the main fuse which then runs to the ignition switch. Newer reg/rec units need to be able to adjust their voltages just like older regulators so do this by sensing voltage through the white (or red or white/red) wire and older regulators had a separate BROWN wire which connected to the switch brown subcircuit coming off the wiring harness. To answer your question about the FOUR wire loom, you could remove the stator cover. Three wires should be soldered to brass windings on the stator. They will be the three AC legs. I am pretty sure it won't matter which goes to which yellow lead on the reg/rec. Look to see where the oddball wire is connected on the stator. That will imply its function. On a stock stator, the wiring harness ALSO has two other wires. A blue wire that is picked up from the oil sending pipe on the back of the engine. This blue will will almost always be cracked and nasty from engine heat. There will also be a green wire that will look almost white (the green fades) coming off the ground contact on the inner countershaft sprocket cover for the green idiot light (neutral light) on the dash board. The stator on a 900 has three mount holes and if yours fits, it is probably aftermarket. There are M6 socket head bolts holding in the cover and it won't come out of the cover easily if you remove the bolts since it is a tight fit. You have to turn the cover open side down and plunk it on a piece of wood till the stator drops out. If you reinstall the stator, buy a new rubber plug and silicon the inside of the cover where the wires go through.

On the permanent magnet alternators that are on the later kawasaki's (78 and newer) the rec (short for rectifier), converts AC to DC. The reg (shorthand for regulator), controls the current output by dumping the excess current as heat.

I just had a look at kawasaki.com, and the 76 KZ900 seems to have a permanent magnet alternator that works as I just described. That surprises me as the 650's and 750 twins didn't get a permanent magnet alternator till 78.

To determine which three wires go to the stator, measure the resistance between two wires, when you find three wires that have a small amount of resistance when measured between any two of them, you've found the three stator wires.

The forth wire should show infinite resistance (open, no connection with the others).

What is the function of the brown wire? Will the charging system still charge if I do not connect the brown wire.

awsome! ok it turns out that the bike not only has an old style reguator but a newer style reg/rec. to my understanding now it only needs the newer style because if does both jobs. yes ill be cracking the motor tonight after work, iv just ordered a gasket from kz-enterprises, so ill trace the wires back.once again thaks for the help guys.
hey george if you ever think of writing a shop manual for dummies ill be first in line for a copy! or maybe on cassete narated by morgan freeman to calm the nerves when i cant get it right, :laugh: :blush:
