Special Man Posted December 2, 2008 Share Posted December 2, 2008 Hey all. Ive got my XS400 up and running then all of a sudden it died! It cranks and cranks but won't fire. I grounded out the plugs and no spark. Changed the plugs (New NGKs), still no spark. Changed the ignition switch and the coils. Still no spark. I do however get a spark out of the plugs when they are grounded if I turn the ignition switch on and off. . . What's next in line to change out? The voltage regulator? Rectifier? Ignitor unit? Any thoughts?? Thanks!! Link to comment Share on other sites More sharing options...

Moderator Cynic Posted December 2, 2008 Moderator Share Posted December 2, 2008 +1 Either the points have closed up or they are bridged in some way. You are performing the same function switching the ig on and off, as in stopping the primary voltage to the coils which is what generates the spark. The one good point from this is that everything else must be ok for it to spark. Have a close look at the points they may have slipped. Link to comment Share on other sites More sharing options...

Special Man Posted December 4, 2008 Author Share Posted December 4, 2008 Well, that was it!! I checked the points and sure enough, the main bolt was loose! Took it apart, cleaned it up, put it back to spec. . . and she cranked right up. Thanks all!! This club rocks!! 1 Link to comment Share on other sites More sharing options...
