i have a 1999 mountain max 600 when i try to start it i get no spark but a little bit of current to plug just not enough to make it spark, but if i unplug the dc regulator it will spark, I've tried replacing all 3 regulators and cdi box also tried a new wiring harness, what else could be causing this problem? bench tested the stator everything except the hand warmer coil on it is working within specs
 
I would suspect the plug caps are due. Or at the very least some moisture got in the wire where the cap is screwed on an its corroded.
 
i tested the caps and they are within specs and its getting lots of fuel i can start it without the regulator just not with it. there was only one ground i could find it was from the wiring harness to the frame i took it off and cleaned it, it was a little corroded but not badly
