Ok so here's the test:
pickup wire (Blue/Yellow) I unhooked, put a lead in and it came up as 0.40-0.44V looks pretty close to what you quoted so I would say there's no problem there.
actual charge wire (Black/Red) I couldn't get unhooked but was able to pull back the rubber cover and put a lead on it. When I first started it it was low like 0.1 then 0.4 then it went up to 1.6v but I couldn't keep holding starter down.
kept doing this multiple times and eventually it would read 3v everytime after a second of hitting the start button.
So I'm thinking the issue is there BUT did I screw up by not disconnecting it? Doesn't this leave the CDI still in the circuit with it? It could still be the CDI right?
Another thing:
I get the 5 wires for the CDI: exciter, pick up, ground, kill switch, and to the coil. but what the heck is the 6th one?
it shows the 6th connected to battery power ONLY when the key is in the on position. Why would the CDI need power from the battery?
EDIT: Nevermind I disconnected the CDI and that pin isn't used lol.
And one last thing!
I found here:http://tgbforum.com/forum/index.php?topic=463.0
that 50V and 0.5v are correct values for those two wires for TGB Scooters.
EDIT: just pulled the CDI off instead of removing the bullet connector halfway to the CDI.
Results:
Blue/Yellow: 0.5-0.37V OK
Black/Red: it does something but appears to show nothing. switches to 0.01 then goes to negative 0.00 stays at 0.00 else.
So I'm guessing dead exciter coil then?
I tried both V AC and V DC modes on my multimeter for the black/red and it shows the same 0.00 most of the time.

So assuming a problem with the stator I think my next step would be to remove the stator and check resistances on the different phases and what not.
Got the nut off the crank but flywheel is stuck on there pretty good. Tried tapping it with a mallet and then pulling on the screws that the fan is held on with but nothing.
Looked at flywheel pullers and it seems like something that could be built...

Or put a screwdriver behind it and hit, then turn flywheel and repeat. One of those ways should work |

One of those ways should work Tried the hammer thing was going to do one hammer on each but couldn't find a second one. Didn't work Can you elaborate on the second method, not sure I understand. |

just pulled mine today advance my timing, I got a fancy puller and it was barely the wrong size. I took a crescent wrench that would barely fit between flywheel and case (handle) and I pushed it in tapped with my hand turned 180 degrees and repeated. it popped right off!

Tried stringing a zip tie through the backside and through the two openings on the flywheel and pulling that. Zip tie snapped though.

Sounds like you need a stator, but it won't hurt to check resistances too.
A steering wheel puller from an auto parts store (or HF prob has them) can work. It pushes against the crank and uses bolts in threaded holes of the flywheel to pull it off.

Steering wheel puller is the way to go,$12 at h.f but the bolts that come with it won't work

It pushes against the crank and uses bolts in threaded holes of the flywheel to pull it off. I saw that at HF but the bolts in the threaded holes of the flywheel look to be too big. the ones I have are M5 threaded.EDIT: I'm an idiot I can just use the bolts I already have didn't realize they don't thread in anywhere into the puller.... EDIT2: Actually it looks like the holes in the HF puller for the bolts to sit in are too big and the head of the fan bolts would just fall through. And yeah I'm thinking its the stator. It's funny it's got 94/11/16 stamped on the flywheel, that's almost 21 years ago! I bet the stator is almost the same age too... It's also got GE90 stamped on the flywheel which I thought interesting because that probably means it's meant for a 90cc which explains the 8 pole design. I was thinking of making my own flywheel puller with a small piece of steel. two holes cut on the outside for the fan screws and one hole cut in the middle. then I stick a bolt in the middle hole and a nut UNDER the piece of steel close to the flywheel. get a wrench and hold the nut while turning a socket on the bolt. should pop off yes? I can make pics to explain the design if needed... Also how universal are stators? would I be better going to an engine rewind shop and getting the pickup one recoiled? is it something I could do myself? |

You could try I would just buy a new one,and u need something with a point so it doesn't mess your crank end up

the end that pushes on the crank has to come to a point?
I would buy a new one but I can't find any 8 pole stator for TGB are they just universal sized?

Is it possible the starter isn't spinning fast enough to create the charge for the spark plug?

It would have to be turning really slowly to only see a couple of volts. Slow enough that it would never start even with a good spark.

What color is the connector on your cdi??
