Title: Help with no spark
Post by: Islandboyil on July 26, 2018, 01:02:41 AM
I have a 01 People 50 2 stroke with no spark. I have changed stater, coil and cdi and kill switch. Fuses are good and there is continuity in every wire I check. Anyone know what I am missing? I want to get this up and running...

Check the coil with an ohm meter and tel us what you found. Primary and secondary.
Title: Re: Help with no spark
Post by: Islandboyil on July 28, 2018, 05:34:09 PM
.8 ohms primary nothing on secondary
Title: Re: Help with no spark
Post by: CROSSBOLT on July 28, 2018, 06:53:23 PM
Whoa, there! Did you change scales on your multimeter for measuring the secondary? I realize how this question sounds but it is crucial for determining what the problem is.

Post by: Islandboyil on July 28, 2018, 07:21:33 PM
What do I set it on to check secondary? Also when I check continuity on the piece that connects to the plug there is none. Is this right? Sorry electrical problems baffles me
Title: Re: Help with no spark

Just set meter to 20k got a reading of 2.54 to the wire nothing to the plug cap
Title: Re: Help with no spark
Post by: CROSSBOLT on July 28, 2018, 08:52:05 PM
Regardless of the secondary, no continuity to plug cap from terminal on secondary is not good. That should read near zero on the lowest scale because it is usually a metal wire. On the 20k scale reading 2.54 should be about right. The way to get better electrically is to do what yer doin': asking questions and experimenting, that is trying to find what works and what does not. Wish I could draw a picture on here!

The spark coil primary is fairly heavy wire with a few turns = low resistance = low scale on meter for resistance. Secondary is very fine wire with lotsa turns = high resistance = high resistance scale on meter. No connection electrically to each other. One end of secondary is grounded, other end is plug wire and cap.

Thanks. I guess my next step is to stop Monday and try to get a plug cap. I might try auto zone to see if they have something that would work. Will let you know

Post by: Islandboyil on July 30, 2018, 07:29:59 PM
8.59 ohms is what I get for the secondary without rubber boot
Title: Re: Help with no spark
Post by: Islandboyil on July 30, 2018, 07:52:56 PM
I am getting .4 volts ac to the cdi. I have a dc fired cdi is that correct?
Title: Re: Help with no spark
Post by: CROSSBOLT on July 30, 2018, 10:08:09 PM
I don't know if it is ac or dc. But I do recognize your information is confusing. Back to basics: primary ohms? Secondary ohms?
Title: Re: Help with no spark
Post by: Islandboyil on July 30, 2018, 11:33:01 PM
.8 primary 8.59 secondary no plug boot
Title: Re: Help with no spark
Post by: CROSSBOLT on July 31, 2018, 12:18:18 PM
 Still sounds like the coil is good.

Let's back up a bit. How do you know you have no spark?
Title: Re: Help with no spark
Post by: Islandboyil on July 31, 2018, 06:56:26 PM
I put a new plug in and ground it to bare metal
Title: Re: Help with no spark
Post by: CROSSBOLT on July 31, 2018, 07:10:26 PM
OK, that's what I had hoped to hear. I read where you replaced nearly everything related to spark. Were all these parts replaced because the engine quit/would not start?
Title: Re: Help with no spark
Post by: Islandboyil on July 31, 2018, 07:45:13 PM
 I recently bought the scooter as a no start no Run. Did some research and decided to just change it all to be safe. I also checked continuity of all wires related to spark. Every thing seems fine. I replaced kill switch because part was missing. It has a new ignition switch also

So we really have two problems: 1. Original no-start and 2. New parts that may or may not be compatible. I saw you other post on AC or DC CDI's. I now realize how this discussion should have been started! That's the great thing about this forum is that the overwhelming attitude is the desire to help everyone and everyone learns something!

Do you still have the original CDI? How is it different from the replacement?
Title: Re: Help with no spark
Post by: Islandboyil on August 01, 2018, 02:51:52 PM
 I do not have the original CDI but it was a big one like a DC fired CDI .  The one I have in there now is a DC fired CDI. The only issue I have with that one is it sits there and homes which makes me believe that it is no good .  That is why I was trying to find out if I should have an AC fired CDI or DC
Title: Re: Help with no spark
Post by: CROSSBOLT on August 01, 2018, 04:37:32 PM
Homes? You mean, hums? What about connectors and colors/numbers of wires? What happened to the original CDI?
Title: Re: Help with no spark
Post by: Islandboyil on August 01, 2018, 07:16:14 PM
 Darn auto correct . On the two pin connector there is a blue and yellow and a black and blue wire. On the 4 pin connector is green and a black and yellow
Title: Re: Help with no spark
Post by: CROSSBOLT on August 01, 2018, 07:31:38 PM
Yes, the auto correct needs to go away! Wire marking is a special language. Solid colors are easy: green, black, yellow abbreviated grn, blk, yel and sometimes by manufacturers g, b and y. Colors with a stripe are usually blue w/ yellow or blu/yel and Kymco wiring diagrams show B/Y. All this just shows how specific you have to be to avoid confusion especially with old guys like me! I think I understand so let me see if I can find a wiring diagram....
Title: Re: Help with no spark
Post by: Islandboyil on August 01, 2018, 07:37:03 PM
I am older myself so I understand
Title: Re: Help with no spark
Post by: CROSSBOLT on August 01, 2018, 07:41:32 PM
I found a wiring diagram but not smart enough to put it on a post. You can find it with search "people 50 2 stroke wiring diagram." It will be the first of the images. We'll work from there...

The wiring diagram is Minarelli which is more sophisticated than Kymco. Further down that search is the complete service manual in pdf for the people 50 2 stroke. The wiring diagram on page 2-16 is hard to read but shows four wires to the CDI, not five.

There ya go!
Title: Re: Help with no spark
Post by: Islandboyil on August 01, 2018, 09:12:22 PM
 I do have a total of four wires two wires in each connector the two prong connector I have blue and yellow and black and blue and the four pin connector I have green and a black and yellow.  I know the black and yellow wire leads back to the coil. They blue and yellow wire in the two prong connector leads to the ignition switch. The black and blue wire in the two prong connector I believe goes to the Killswitch
Title: Re: Help with no spark
Post by: CROSSBOLT on August 01, 2018, 09:46:02 PM
One of those wires goes to the pulsar, one to coil. I'm stopped there without the correct diagram. Does the diagram you have match what you see on the bike?
Title: Re: Help with no spark
Post by: Islandboyil on August 01, 2018, 09:50:03 PM
 Yes the blue and yellow wire goes to the Pulser coil  that intern goes up to the CDI
Title: Re: Help with no spark
Post by: Islandboyil on August 01, 2018, 09:53:37 PM
The black and yellow wire goes from the coil up to the CDI  that is in the four pin connector with one green wire
Title: Re: Help with no spark
Post by: Islandboyil on August 01, 2018, 10:07:26 PM
 I just watched a YouTube video from rolling wrench  Denver about CDI’s it appears I should have an AC fired CDI not a DC fired CDI so I guess my next step will be to get an AC CDI box and give that a shot
Title: Re: Help with no spark
Post by: CROSSBOLT on August 02, 2018, 12:59:24 AM
Alright on that! Sounds like you are hot on the trail! I can't wait to hear the next thing!
Title: Re: Help with no spark
Post by: Islandboyil on August 02, 2018, 09:29:29 PM
 I just installed an AC fired CDI.   I tried it and nothing no spark.  On the black and blue wire that goes to the CDI when the ignition switch is on I have 12 V
Title: Re: Help with no spark
Post by: CROSSBOLT on August 02, 2018, 09:50:05 PM
Is 12 v supposed to be on that wire? Is the pulsar plugged in?
Title: Re: Help with no spark
Post by: Islandboyil on August 02, 2018, 10:11:21 PM
 I will try to post pictures later of how my CDI is wired
Title: Re: Help with no spark
Post by: Islandboyil on August 02, 2018, 10:13:27 PM
Should only be power there if it is a DC CDI and yes the Pulser coil is plugged in.
Title: Re: Help with no spark
Post by: CROSSBOLT on August 02, 2018, 11:55:00 PM
Yesterday, I did a crash course on CDI hookups and the AC CDI's are hooked to a coil in the stator, the DC's are wired to 12 volts through the key. Referring to your service manual, what powers the CDI?
Title: Re: Help with no spark
Post by: Islandboyil on August 02, 2018, 11:59:33 PM
 I believe it is the battery because I have 12 V at the blue and yellow wire
Title: Re: Help with no spark
Post by: Islandboyil on August 03, 2018, 12:01:16 AM
 Blue and yellow wire comes from the ignition switch
Title: Re: Help with no spark
Post by: CROSSBOLT on August 03, 2018, 12:12:19 AM
That tells me in my ignorance that you have a DC CDI. NO, that is not conclusive. Heck, I don't know. Is there on the circuit diagram BOTH a coil in the stator AND 12v from the key hooked to the CDI?
Title: Re: Help with no spark

Mercy! Nothing matches! What does the wiring diagram look like? Can you do a picture of that? Or at least of the CDI-ALT hookup?
Title: Re: Help with no spark
Post by: Islandboyil on August 03, 2018, 10:47:33 PM
Here it is
Title: Re: Help with no spark
Post by: CROSSBOLT on August 03, 2018, 11:57:00 PM
OK, that makes sense. You have a machine that takes a DC CDI. Your harness has 4 wires, the diagram shows 4 wires to CDI, there is no coil to the CDI except the pulse and there is the DC wire to the ignition switch. Even the colors match what your picture shows. DC CDI.
Title: Re: Help with no spark
Post by: Islandboyil on August 04, 2018, 12:00:10 AM
Ok. I have an unrestricted dc cdi that I will have to try tomorrow. I was wondering if it could possibly be the ignition switch??

Tried dc cdi no spark. Tried hot wiring no spark
Title: Re: Help with no spark
Post by: CROSSBOLT on August 04, 2018, 10:05:23 PM
Assuming replacement stator including pulsar coil good then CDI defective. All parts new in box?
Title: Re: Help with no spark
Post by: Islandboyil on August 04, 2018, 10:08:56 PM
Yes all parts new in box. Cdi was bought from eBay. I will have a new cdi ordered from kymco. Probably take a week to get. Will keep you posted

Chase down all grounds, take 'em apart, clean 'em, put 'em back together after you have ensured all terminal lugs have continuity with wire and no corrosion.

Post by: Islandboyil on July 08, 2019, 11:10:55 AM
After  tracing wires, checking grounds, and replacing anything to do with spark I found the problem.  I checked the ignition switch and it was not working. I ordered a correct switch for this model scooter installed it hit the button and it started running right away. Thanks for the assistance in getting my scooter to run and for me to learn from this group

Alright! That gives closure! Now, what would you have done different if you had to do it over?
Title: Re: Help with no spark
Post by: Islandboyil on July 08, 2019, 12:34:27 PM
I don’t think I would do anything different. Had to check everything and replace bad  or out of spec parts. Got scooter as a no start no spark. It was definitely a learning curve
