Question on Stator By epdowd (Read 3,665 times)

I have a Znen Pacifica with the 157QMJ engine. I have suspects about my stator going on the fritz. Engine quits intermittently, plug checks good(very weak-some times no spark, swapped Plug, Coil and CDI. My problem is, before I take it apart I am looking for a decent wiring diagram that matches the colors I have coming off this stator :
3 - Orange, 1- Blue, 1-Gn. All the diagrams I have found show:
1 Green, Red, Yellow, White, Blue
I'm sure the Green is Ground and the Blue goes to the CDI.
Is there a proper hook up for the three Orange wires and can I tell before I take it apart,, is it a 6 coil Magneto.
Thank You.. Harv.

I think most 150s have an 8 pole stator mine does. I believe the 3 orange all put out the same amount of VAC so it really does not matter, they would go to the R/R/.

Hey Harv, the three orange wires are yellow wires carrying AC voltage to the rectifier. The blue is your trigger coil and green is ground. What is very odd though is a six coil stator cranking out three phase. Well, it is what it is. The absence of a red/black wire from the stator to the CDI tells us it is a DC fired CDI. The Y, W, G stator harness is for a single phase, AC powered CDI system and it won't apply to you. So hook your three orange wires to the three orange (or yellow) wires on the R/R in no particular order. Hook the blue trigger to the CDI and the green to ground. Can you tell me what the R/R has for wires? Sometimes there's a white AC that powers the auto-choke or even some lights.

Alley and Bash.. Thank you for the replies !!.. I'm a bit slow getting back on this..
That sure helps explain the difference on D.C. and A.C wire colors. I figured my wire colors must have been the only left over wire the Chinaman had left hanging on the wall of his garage !!.
The wire colors from the R/R are 3 - Yellow, 1 - Black/white and 1 - Green. I didn't take the cowl off to verify this, but it is the wires coming out of the loom to match up with the R/R that matches up with the orange, Green, Blue on the Stator side..
The Stator may be 8 pole, I was just asking if (6 pole) you could tell before I took everything apart.
The Green wire looks melted in some spots . How does a Ground wire over heat when the other four look OK ?.
I guess I'd better order a Flywheel puller,, Huh ?.
Thanks again, this is the Best Scoot forum...
P.S. How do I know if I have an A.C. or D.C. Stator ?. I know now that I have a D.C. R/R. Thanks.. But does the Stator put out A.C. , then Rectified, filtered by the R/R to D.C. then to the CDI. eh what ??
The Stator is a 3 pin, 2 wire.

Refer to above: How come all the Stators I'm finding have the Yellow, White, Green wires. This is where I'm confused on having an A.C or D.C. Stator. ??. Thanks..

ALL STATORS produce VAC voltage the R/R is the one that converts the AC Voltage to DC for your lights and battery charging. When they ask if it is DC or AC system it REFERS to the CDI.

There are CDIs that are 12v FED and not AC FED. The DC CDIs get there voltage from the BATTERY and the way that works is the Battery Always feeds the IGNITION SWITCH and when you turn the KEY on it feeds 12v to your other electrical parts of the scoot, lights, gauges etc.

If you have a DC CDI when you turn the KEY ON it feeds 12v to the CDI.
If you have a AC CDI when the FLYWHEEL ROTATES(you use the kickstart, or electric start) it then feeds AC voltage to the CDI to create the spark.

You can check what type of CDI you have very easy, Turn the KEY ON test the BOTTOM WIRE(POWER WIRE ON the 2 PLUG SIDE OF THE CDI) and if it reads 12v it is DC if nothing it is AC).

Thank you alley !!!. I've been going around in circles trying to figure out a D.C or A.C. Stator. Figured there must be some voodoo in a D.C. Stator...

To elaborate on the venerable Alley's oration, ALL stators generate AC voltage. If it generates DC voltage, it's a....well..er generator! So I really don't like the designation of is it a DC system or AC system. They are all mixed to some degree.

The ONLY electricity that comes out of a stator is AC.[/U] The difference between an AC and DC system is how the CDI is powered. If there is a black wire into the bottom of the CDI two connector that shows 12v DC when the key is on, it's a DC fired system. This stator will NOT have the red/black AC wire and the dedicated magneto coil to power the CDI. Instead, an AC system has the red/black wire from the dedicated magneto coil plugging into the bottom of the two connector to power the CDI. This wire is neither regulated or rectified, hence the 50 to 100v AC on the multi-meter.

I have to go to the PO and get a hard drive I need to fix a laptop for this lady. I promised to have it done by tomorrow so I have to bolt. If anybody wants me to continue this diatribe by going on to the R/Rs just say so and I'll be glad to when I get a break. I can do a diagram too if you want. Rich[/b]

Thanks again Rich. I think what threw me and maybe others is the misnomer - A.C or D.C Stator. I couldn't see how you could get D.C from an A.C device. Also the many differences in color codes involved don't help.. I've got it now tho. I mainly wanted to get my head straightened out before I take the thing apart, order parts and etc.
Thanks again for the help,, Harv..

gee you guys got this one covered !
