HELP!!!!!

Post by brayden55 »

yesterday i bought a 1995 kx 250 in about 10 boxes. everything was redone (frame, engine, ect) so the guy i bought it from said that the shop bench tested it. so today was my first real day working on it so i thought i d test and there was no spark! i tested all over it and i think that it is the "exciter coils" there is 2 undernieth the flywheel. i have never hear of a exciter coil befor and was sondering if it would cause it to not spark. the engine did sit for about half a year after the rebuild.

any help would be appriciated

was the engine mounted when you tested it? there are grounds to chassis on for the coil and the stator so if it isn't done i'd build the bike off the manual to make sure everything is connected and then start troubleshooting from there.
There's no point in bench testing as everything is accessable when assembled on the bike. there is just to much to go wrong otherwise. my opinion anyway

i have the engine in the bike and am now troubleshooting nut it was bench tested half a year ago. iv tested and there is no current trough the stator coils. it looks like moisture got into the rotor housing when it was stored for half a year. have you heard about moisture wrecking the coils?

well i've seen one that is pretty rusty but still working, to test the coil set your digital multi meter to ohms and read between the white/red and black coming out of the stator cover. (These are the colors on the 200's stators i've got.) You should read about 360 ohms or so but not 0 and not infinity.
the only other wire coming out of the stator is the lighting coil which is a seperate entity for your lights, on mine it is a yellow wire. on a 200 at least it has nothing to do with spark.

that would mean a shorted coil, are there 2 ignition coils? or is one a lighting coil.
