You'll have to check the voltage at the CDI to ensure that you are getting the right power from the stator. See the thread link below. You'll need a multimeter to check the outputs of the stator/CDI.

Joe helped me out when my stator went bad.

OK, as I posted before, if you get a spark with the black/white wire disconnected (when before there was no spark) then there is a problem with the wiring and/or switches that are intended to kill the engine.
It also means that the stator, CDI, coil, HT lead, and plug are at least in good enough condition for the engine to run so no problems with those.
That just gets the problem narrowed down very nicely.
So, the ignition switch, kill switch, or the sidestand switch will kill the ignition, (ie. ground the black/white wire) if they are in the wrong position of faulty. The side stand must be UP, kill switch to RUN, and the ignition to ON to get a spark. Of those, a faulty side stand switch has been the most common. That's where to look first.
Now, for the other non runner, it seems that you still have no spark with the black/white disconnected. Correct? If so, then there is a problem with the stator, pickup coil, CDI, or coil or the wires and connectors leading to those parts. It will take some testing to determine which it is. But, lets work on the easy one first and then come back to this one.

| They both are getting spark now. I'll check the stand switch. Thanks for your assistance!!! It is 10 A and I don't leave for work till 1P.

Kool, you have a similar problem with both scoots then. That should make it easier. Let me know how you make out with checking the side stand switch(s).

Not all scoots have one, but most do. Check one or two of your other scoots to see if you can locate one. A scoot that will not start with the side stand DOWN will have a switch.

It's hard to tell from the photos. The first one would not even open for me. But, a switch that is activated by lowering the side stand would be the one.
Well, swapping out parts is one way to find a faulty part. However, you have a spark with the black/white wire disconnected on both scoots which is a clear indication that the problem is not with any of the parts that you may have swapped out. You may have disturbed some wires somewhere but I don't really know. I made a recommendation on where to looked based on the current condition showing no spark with the black/white attached and having a spark with the black/white disconnected. The purpose and meaning of that test is very specific to isolate the area of the problem. Your problem is with the switches and wiring going to them and not with the main ignition components.

| So, basically you are saying it is the switch and or wire to ignition & kill?

The yellow one is back to normal. I sprayed silicon on all switches and connectors.
The black one will still not start. It will get spark with out the Blk/White wire connected to the CDI.

Look, the the stator charges the capacitor in the CDI with 85 to 120 VAC. At a signal from the pickup coil, that voltage is discharged through the coil to produce a spark. But, the black/white is connected to the capacitor in the CDI and is routed to the ignition switch, kill switch, and side stand switch. The ignition switch, in the OFF position will GROUND OUT the capacitor in the CDI which results in NO SPARK. The kill switch in the STOP position grounds out the black/white and no spark. The side stand switch grounds out the black/white when in the DOWN position and so NO SPARK. That is how it is supposed to work.
You have NO SPARK when the black/white wire is connected to the CDI but you DO HAVE SPARK with the black/white disconnected. So, the black/white is GROUNDED OUT somewhere causing no spark when connected. It seems that the black/white is grounded out even with the ignition to ON, the kill switch set to RUN, and with the side stand UP. One of those switches is faulty and causing the black/white to ground out or the wire itself has become chafed and is grounding out to the frame or engine. This is not guesswork, it is based on the observed spark condition with the black/white wire connected or disconnected. You do have NO SPARK with the black/white connected and SPARK with it disconnected, right???
I don't know how to make it any clearer than that. It is up to you to find the faulty switch or wire. I only suggest that that many more members here have had problems with the side stand switch than have had problems with the other two switches.

I'll give what ever you say a try......
I have a friend there that wants to ride if he heals up in time. I am planning to get down to TN in the spring for a few days and would be about 1/2 way there.
