should be 0012 or so on 2000k setting. One end in ground and other end in the spark plug cap right?

I try it in the cap, the wire without the cap, and straight off the coil. All the same. Now, I tested my super 9 the same way and read 0012. Then, I swapped out the coil and wire with an old, but still fully functional at removal, coil and wire. The thing was at 1000+ on the 2000k setting!

Switched caps, brought the reading to 0008, put the cap on my super 9, came up with the wild reading, but I've been running it all day with not a problem... Back to the drawing board. I may order a stator sometime. Let me know if yours gets fixed and how it goes

if not the cap, then maybe the coil?

I'm getting the same readings with a different coil. I'm even about to just pull the known working one off the Super Nine and try it. It just makes me want to think that the spark is too weak and that it gets weaker when ran hard. I can hold the wire and turn it over all day, not bad, but on my other scooters it will bite the hell out of me. I'm wanting to try a different cdi, but I also don't want to waste my money. There's a guy across town that has a bunch of random scooter stuff, he might have one for me to try that is the same layout.

Well your stator checks out resistance wise, and a new one is $100 and 2-3 month wait or $140 and 2 week wait so I would narrow it down before you try that route.

Coil checks out. Sparked the hell out of me on the s9. So, the stator numbers seen right, the coil works elsewhere. I'm going towards cdi again. Any way you could get a few readings for me, or if you know the internet location you could share it? The guy I was talking about sold everything to another guy, he's got cancer and doesn't want to deal with the shop anymore. I'm going to talk to him tonight and hopefully he has something, or info.

Set your voltmeter to AC voltage and black probe in ground red probe in the black/red exciter coil coming from the stator. take the boot of the plug and crank over the e-start, should read somewhere around 40-60v

That's what I am thinking my problem is, possibly. I tested with the multimeter in acv setting with no reading but in dcv I was getting 18-20...

I don't think any of the CDIs have been tested on the R50x, I haven't read of any confirmed to work, but it was one that Jwhood suggested and he had it running on his keywest, which is identical hardware. 200 AC V setting? your reading the black/red wire coming from the stator, correct?

Yep, from the exciter, black and red, read 305 ohms resistance. Tried the 200 and 750 acv setting, I think one read .1 at some point, the dcv setting at 200 and 750 read up to twenty. I guess I could order one of those cdi to try. First I'm going to put on a different rotor I have around to see if that changes anything.

The voltage regulator / rectifier only deals with the lights etc, and charging the battery, right?

correct, the spark plug timing signal and power both go directly from stator->CDI->coil->boot->spark plug
if on 200 you get 18-20V that would indicate weak spark and since its from the stator it would have to either be the stator windings or the flywheel magnets.
it's weird that you aren't getting anything on the AC mode, maybe it's just your multimeter. I think DC will give you a reading because technically 20V AC is like 20V DC then -20V DC then 20V DC so I'm not sure how it comes up with a number to show you. It might not be accurate.

Okay, went back out and checked again. On 200 acv I'm getting a reading of 00.6. I pulled the rotor off the stator, it looks great with great magnetic pull, the stator looks brand new, has a date stamp of 2012/02/13, so that's clearly been replaced. The part that is on the outside of the rotor has magnetic pull also. Just some more details...

strange... I don't really know what to tell you.
