Stator and CDI wiring By epdowd (Read 11,176 times)

Hello all, It has been a while since I came on the forum.. I'm confused as usual.. I have a Znen Pacifica 150 ZN150T-18 and I'm having trouble figuring out the color hook ups for the wires on the CDI and Stator. My colors and number of wires don't match up. The Stator is an 11 pole. Wires coming off are 3- Yellow, 1- Green, and 1- Blue and White.
The three yellows must go to the Voltage Reg., Blue and White is the Pick up or Trigger wire, but it connects to a Black and White wire. A Green wire to Ground. I don't see The power wire that is supposed to go to the CDI.??.
The CDI only has four wires to it. Three wires (BK/WT, BK/Y and Green) to the four section terminals and One wire (BK) to the two section terminals. I can't seem to find any Schematic that matches up with the amount of wires or color codes. The schematics I've looked at all have the Four wire - Two wire to the CDI. My problem is no spark at the plug. I've swapped the Plug, Coil, CDI and Stator..The Kill Switch is in the OFF pos. Sure could use some help on this. Thanks..

Harv!! We have missed you my old friend! Nice to have you back. Here is a link to a recent thread I did on the 11 coil upgrade. You can read that over and I will see if I can work you up a diagram plus I'm going to do more on that thread tomorrow. So we'll get you straightened out. What have you been up to bud? Rich

I think it is dc cdi , can you post a picture of you old stator be sure to show the connector , with wires and color .

Thanks for the replies, I'm happy to be back on the Best scoot forum !!!. I backed off on the scoots when my wife went through open heart surgery that thankfully worked out very well.. Then I reluctantly acquired Glaucoma mostly in the right eye. The Doc has that stabilized but poor vision in that eye.. Things are going fine tho and we're happy.
Thanks for the encouraging info on my Stator and CDI Bashan.. That will sure help..
Hello John,, I'll see how adept I am getting pictures in here tomorrow, Thank you..
Harv..

John is right and you are right Harv! You have a DC CDI so it is energized by a black wire that comes from the battery, through the R/R, and then becomes hot when the key is turned on:

OK, this gets a little tricky. The blue/yellow is indeed the trigger Harv, but it probably has a butt connector that changes to a white/black on it's way to the CDI trigger port. Why does it change to white/black like a killwire...because it's a killwire! PROBABLY the B/W continues on from the CDI and hooks onto the keyswitch. When you turn off your key you ground out the trigger and boom the engine shuts down. To test this, set your multi to continuity, put one probe up against the B/W in the CDI and see if you have continuity to ground with the key off. If you do then turn on the key, if you lose continuity you just found your killwire! It can't run with the key grounding out the trigger signal. It's just like grounding out the coil with your standard kill....only different.

Your black wire is the only wire that plugs into the two port because the kill is already taken care of. You're not using an AC feed from the stator, you're using a DC feed from the battery. That's why there's no red/black wire like a green/yellow/white single phase stator. You have a three phase stator which accounts for the three yellows. Some of the three phase also have a magneto coil which would give you a red/black AC feed for the two port if it's an AC CDI. But if it's a DC CDI you MUST use a DC feed from the key. Coil hookup is the same, yellow black to positive coil terminal. Ground one, or both, ground ports on the CDI. That should cover all of your wires. Let me know if you need more help. Rich

Thank you very much for the diagram and explanation !!. Now I have something I can follow..
I'm wondering why all the trouble shooting help has been with AC Stators vs. DC ?. More AC systems ?..
Anyway I took my shoes off and recounted the coils on the stator,, there are twelve,,, not eleven,, DUUHH..
OK, I'll get back to the scoot and hopefully find my problem.. Thanks again..
P.S. I entered the pic's of the Stator and CDI sort of after the fact for practice..

Can you take some measurements ? Outer diameter , bolt hole spacing ?
It is dc cdi .

John, the Stator diameter is 3 and 7/16 inch. 2 holes, 1 and 5/8 from centers.

Ok, still no spark at plug (new Plug). Kill wire checks good to ground with Key On and Off and Kill Switch On and Off. The problem I found is with ohm meter lead on a good ground at the battery and the other lead to the green ground wire I read about 3 ohms with key Off, key ON reads 20 ohms. This is with all the green wires disconnected from Stator, CDI, Coil, Enricher and wires to the back of the scoot. Before I take off the front panel to get to the Rectifier and Key switch is there any reason I should read 20 ohms to ground on the green wire with key on.. Key OFF = 3 ohms. Key ON = 20 ohms. ? Thanks.

I would pull the bkack/white eire from the cdi and see if you get spark .

Since yours is a DC CDI, the killswitch cuts off the 12volts to the CDI, same with the KEY OFF it cuts the juice going to the CDI. Now you probably have a KILLSWITCH on the SIDESTAND as well.
