no spark...again By godfeast (Read 648 times)

OK, went out the other night to go home from work and the scooter didnt fire up.

NO SPARK

I replaced stator, coil, and cdi.

NO SPARK STILL

I then tore it apart today and still cannot get it to spark ( I removed the black+white wire from cdi to take the kill switch out of the equation and ground the green wire to the frame ).

I did notice that theres a slight bit of current running from the ground wiring on the harness to the red+yellow wire that comes from the starter solenoid... Found that out when I removed the ground wire from the stator cover and it sparked when it came into contact with the engine body.

This isnt blowing my fuse, but is it causing no spark? I have no clue.


Anyone know?

Yep! Unplug the R/R and see if the spark on the green wire goes away. Sounds like a shorted R/R which would feed voltage from the battery to the red wire on the R/R then it would cross over to the yellow wire which ends up on the green as ground after it runs through the coils on the stator.

If that doesn't do it then you need to open the harness because you've got some wires fused together.

Also you need to test the black/red wire on the stator while turning the engine over to see if you have from 80 to 100Vac.

Just because you replaced them doesn't mean they are always good, happens with Chinese electrical.

Yeah stator was bad - found out because I gave up and took it into a shop and 140.00 later it runs, but with a new issue.

will make a new post for that.
