All the green wires read a good ground.

Your CDI is probably toast. It's getting power, it's getting trigger, and it's putting out squat to the ignition coil. The only thing that makes me a little hesitant to say that is I believe you said you swapped out the CDI...correct? Sometimes you get a bad component after the other one fails. It's happened to me. If it was a bad kill switch you wouldn't be getting anything at the coil feed. I'd say 90% probability it's the CDI. I can't think of anything else that it would be. What happened with the stator ground, the one that was roasted? That shouldn't do it though because the power is from the battery. Guys, any other ideas before he orders a CDI? Sock it to me..I don't care. I just want Harv up and running again. Rich

Thanks Rich. The green wire wasn't toasted just looked like it might have overheated. I noticed it when I took out the old stator. It wasn't the wire from the stator but the wire that it hooks up to. Maybe a high resistance connection. It reads ground ok. I'll get another CDI. We have to go to Michigan the 6th, be back the 13th so you can give a sigh of relief on this nightmare. I'll keep digging on this as soon as I get back.. Thank you all for the help. Great forum. Harv..

Mr. Misery is back...I bought a new CDI from John.. I now have spark,  ,,,, BUT  the Ground wire to the Stator gets very hot. I try not to crank it very long because that is probably what ruined the other two cdi's. It reads a good ground. I have all the ground wires disconnected except for the ones I need to crank. I also read a very erratic voltage DC and AC on the stator ground wire when cranked. Now - The old stator had an over heated ground wire and so will this one shortly. Any ideas on this. I guess I'll take the wire bundles apart. That voltage has to be coming from somewhere because a ground sure won't create voltage. Thanks,,, Harv... |

Run a wire directly from the CDI to the negative battery terminal and see if it heats up. If not, there is something wrong between the CDI and battery. The ground ultimately ends up at the battery terminal so you're just cutting to the chase. It's not any kind of work around compromise. Rich

The green wire on the stator gets hot when cranking , because the engine ground has a problem or is missing .

VERY good point! Better than the one on your head. No, seriously John, that was very astute. Harv, also run a ground from one of the valve cover bolts right to the frame or better yet, the black battery terminal. Rich

The green ground wire on the stator burns because of not having the heavy ground wire connected to the engine . If you kick start the engine is fine it will not burn , but the heaver load of the electric starter smokes/burns it . One things I look for when trouble shooting an electrical start /spark problem .

 The Chinese Enigma Machine is up and running.. Thanks to you fine gents and this forum !!. I ran 12 ga. wire from the battery to the frame and engine. No more hot green wire when cranked. I don't know whether to be happy, embarrassed, or mad at this whole debacle. Evidently, this scoot was made with a crappy ground and it took this long for the problem to finally show up ?. I'm sure glad that you suggested a new cdi. With the two unknown bad ones I didn't get the hot green wire when cranked.. I have 638 Chinese miles on it, so using the starter over that amount of time finally went on the fritz ?..Delayed booby trap ?.  ?. Thanks again and there are a bunch of us that rely and appreciate all the help and knowledge we get from this forum..  Harv..
