I just purchased a 87 XR600R. It ran fine until this morning. Could not get it started. Checked for spark (new plug) and no spark. Since stators seem to be a weak point on these bikes, what is the procedure for checking it (I'll have the factory manual in a few days). This bike has only two leads coming from the stator (blue and black/red), should there be continunity between these two leads? resistance from each lead to ground? I understand that the 5 coils (ignition/4 lighting) on this stator are interconnected? Even when the bike ran, I had no lights (bulbs good). Between the Black/red lead (ignition?) and ground, I measure 82.5 ohms Between the Blue (lighting?) and ground I measure .8 ohms Between the Black/Red and Blue leads I measured 83.3 ohms. These measurements were taken with my Fluke 87 True RMS DVOM. Any tips would be appreciated. Thanks.
