Well lads I performed the checks. Power into CDI 13.0 VLTS
Power to coil 0.1 ACorDC either way (should be 12vlts)
Trigger wire at CDI end 0.4 ( should be 2.1 VLTS)
So trigger wire and coil power wires are way belows specs.
even when i checke the trigger wire back where it makes its 1st connection from the unit, its the same so no loss between there and cdi. It Looks like a bad CDI 13vlts in but0.1 out to coil and a bad pulser/trigger at only 0.4 instead of 2.1 VLTS.

I am still at it here. How to check the voltage from the stator. I have 2 wires. Pink & Yellow. How should i hook up the tester while cranking the engine?Check each wire seperately through the meter to ground or check between each? I dont want to short anything out here.

OK Lads, I ust checked the pulser coil unit wire and it reads .4 Vlt AC. I guess its bad because the CD i have says 1.5 Max but i dont believe it even spscifies AC/DC . I am going to have my neighbor come over and see if he can figure out how to post the schematic I have from the CD. One thing i have found out is the model 125 and S125 are WAY different . In the beginning i assumed the S designation only refered to plastic body parts for styling. When you compare the schematics there is a big difference. The funny thing about the schematic for this S model never shows the 7th wire . It connects to a similar looking unit although slightly smaller than the CDI . Now I am fairly convinced the pulser coil is the culprit because of the border line reading and will search about pricing one .

Back again with a humble report. I went out and rechecked the wire from the coil to cdi and end to end continuity ok there. Tried each end to ground and no beep so i must have been hearing things. The wire from the puls coil which i tested earlier for ohms and showed ok was checked for continuity to cdi and its good also. So i dont have spark or voltage at the coil . The voltage is going in to the cdi but not out to the primary side of the coil. I am remembering fondly a Harley Davidson Topper scooter i had. Soooooo simple . Give me point ign any day.

Here is what i tried today, Tested the puls coil and got a reading of 105.5 reading should be bet 70 & 130 so ok there. The puls coil wire goes to cdi as power in i would guess and a wire comes out to the coil. When I check the primary side of coil i get no voltage. Shold read 12vlts. After testing things and replugging everything back,, I shorted a plug to the head and had great spark. Then I put the plug wire on the plug in the engine expecting an instant start. NOTHING. Undid the plug wire and went to the plug grounded to head and NO SPARK AGAIN. The Ohms readings on the coil are well within specs. Primary and secondary w& without plug wire attached. I am thinking if the cdi is wacky, could I hook a hot wire from the bat to the coil and get my 12 vlts there an see if it starts. If it does then it tells me there is no power from the cdi to the coil. But i am concerned with burning something out . Now like i said no voltage to coil either just with the ign switch on or when its on and cranking the engine. I remember that when it was running a while back I checked the alternator output and at the bat terninals i was getting 14+ vlts so I am sure the alt is OK. I also checked the engine to frame and its Good as gold.

MY cd gives tersting process but specifies a specific brand tester because of a semiconductor in the unit so that put a halt to that. I went to the elect section and looked into testing the out from the stator but the wiring description dosent match up. My unit has only 3 wires from it. 2 attached to a plug (pink & Yello ) and a 3rd which is blue w/yel tracer which is attached to a seperate bullet type connection and with this arrangement i cannot perform the test for stator output. Another curious thing is where the 2 cdi units are explained (AC/DC) it shows the AC as having 2 plugs (#1 with either 3 or 4 wires ) and #2 as having 2 wires . The DC is described as having #1 3 or 4 wires but #2 as having 1 wire. Now mine is as described by the AC setup but the Monsterscooterparts website states Kymcos are DC . The repair CD I have dosen't even list a color code sheet or a wiring diagram which would be real nice. I am about to give up.
