do you have the manual?also make sure the engine has a good ground

If good and it works (as in makes your T-3 run again) for you we will work something out price wise.
BUT, have you pulled that Ricky fly wheel off and checked to see if something did not get picked up on the magnets ,,, like say the fly wheel key ~ please check.
To the very best of my knowledge no matter if key way is in or not,,, so long as fly wheel is turning it WILL make spark (just at the wrong time) but if something like a key way or some other piece of crap go in there it may be direct shorting it all out.
You check that, I will check exciter coils.

P.S. - where the 3 wires from exciter coils plug into the wiring loom, make sure they individually are pushed together. I have had one of those wires work loose from the black encapsulation thingy around the end,,,

I will check the flywheel tomorrow, Ive taken it off many times but never really looked on the inside of it. The key was always on the the crank and looks okay. The flywheel itself, I see turning as I have the cover off when I'm hand pushing the kick starter, watching for spark. The new stator was inside when the the old flywheel flew apart, but it looked fine! I'm going to buy an Ohm meter tomorrow and test it according to the manual. Thank your for the help everyone.

you can't hand push the kicker to see spark. not turning it over fast enough. you have to kick it like your starting it.

when the flywheel blew, did it nick or break any wires on either stator coil? if 1 wire is broken you won't get spark.

even if theres no key in the flywheel, you'll get spark, just be out of time.

I could always see the spark when I hand kicked it before this, but I'll try kicking it and having somebody watchin for spark, I'm desperate at this point.

Yes a pdf version. Sorry I really didn't get what you meant by the "engine having a good ground" I really think its got a ground issue, however I only see one ground wire and that's the one from the CDI (solid black taped with the green and white)

Guys I checked the flywheel and it was very clean inside, the stator also appeared to be perfectly fine all the wires were still glued on and secure. I tested the stator with a ohm today, I took the 3 leads from the black cap, from the stator, and touched them according to the manual, BK-BL=200, BK-W/R=226, BL-W/R=26__(the Ohm meter started to beep when I did this one not sure what that meant).

Jes I played around with the leads coming from the stator into the 3 prong boot and one of the female plugs must have been too far back because now I'm getting good spark. Thanks for all the help everyone. I think I'm having timing issues now though.. because its popping and acting like it wants to start but fighting its self to. I had to stop but I'm going to mess with it more later on today. The only way to time this things is from the stator correct? Because I have the stator aligned with the marking on the crankcase, but there's a marking on the flywheel as well, 3 dashes, does that have to be aligned with something too?

**sblt500r** · 03-19-2012, 02:24 PM

i had to hook up a timing light to set the timing. some reason the stock marks are off? you move the stator to set timing, marks on the flywheel will line up with the point on the case when the timing light is hooked up. but it has to run to set the timing with a light.

Okay so I changed the spark plug then and set the piston to the top and the this thing fired right up, then died 20 or so seconds later. Now I have no spark.................. It sounded fine when it was running no puffs or pops, just died.......

**gage** · 03-19-2012, 03:40 PM

Do I need the kill switch on it for the CDI to work properly?

**jeswinehart** · 03-19-2012, 03:45 PM

Oh wow gage what a brain tease ! Got spark, had it running, diead out and now no spark ~ wow.
I had to tape the 3 wires coming from stator to keep mine from unplugging its self. But I am sure that you already double checked that ,,,
I know there are 2 ground wires at the front of the coil but I am at work so not sure what they are from but again, I know there are 2 there.
Both use the front coil mount bolt to hold them against frame.

**gage** · 03-19-2012, 04:03 PM

ya ones coming from the CDI, solid black, the other which I have disconnected, is from the kill-switch which is black & yellow. Both under the ignition coil on the frame. I have no clue whats going on, can't believe this is giving me this much trouble, I mean I tore this thing completely apart near 2 months ago and it gave me no troubles whatsoever, (except a bad carb).

hat i meant

what I meant is the engine needs a good ground to the frame at the mountinting points. If you painted the engine wile you ahad it tore dore it's possible the engine doesn't have a good ground. strip the pant at the mounts on the enginge and the frame and test for continuity between the engine and the frame

Ya but it was running before this. I sanded down the frame where the ignition coil goes though....I'm not sure what to do now Ive honestly exhausted all efforts..I think it has something to do with this new flywheel, or some how the CDI messing up.....

**gage** · 03-19-2012, 08:11 PM

I guess I'll just buy a new plug tomorrow and try it, maybe its just making a weak spark and I can't see it. It was a little wet and black when I took it off maybe it just flooded it self out. But I'm very doubtful...You guys run the stock plugs in them right BR8ES?
