Had a problem starting, traced it to no spark. On inspection I found one of the coils on the SIL electronic stator burned out. I have since replaced the stator, still no spark. I put an electrical tester on the green wire coming from the stator and kicked the engine over, but no power. Tried the same on the yellow wire from the stator, which is for the lights and the tester lights up.
Should the tester light up when connected to the green wire from the stator? Any other ideas as to what could be wrong?
Thanks

Brand new stator plate fitted. Could be faulty I know. Wondering if theres a way of testing the stator while in situ?

Yes there is, you will need a multimeter ( a cheap one from Maplin or ebay will do) connect one lead of the meter to the engine case and the other to the white (stator earth). With the meter set to read ohms, you should be seeing close to zero ohms. Move the test lead to the green (LT coil) and you should see somewhere between 450 and 500 ohms. Then move it to the red (pickup0 which should read between about 95 to 115 ohms. If the white is higher than 2 or 3 ohms you need to check the tightness of the earth tag on the stator which the white wire is soldered to as these are often loose and need tapping with a hammer. Let us know what readings you get.

Ok all checks done as suggested. Good earth between engine and frame. Readings on the green wire was 450 and the red wire was 95. I've even tried a cdi from a running scooter but still no spark! Any more suggestions anyone?
I've contacted the supplier of the new stator and asked for a replacement, can't think of anything else that it could be :cry:
