hi, i have a 98 mxz 440 and im trying to diagnose why i have no spark.  i think
i have it down to the trigger coil as when i hooked up the volemeter to it, the
book says 2-9 volts when the engine is turned over, but there is none.  so, i
got a new trigger coil thinking that this is the problem, but after replacing
it, there is still no voltage.  so, my question is what else could it be??? i
have the mutimeter hooked right up to the line from the trigger coil and im
sure its making a connection, but no voltage whatsoever.  so, could it be the
flywheel somehow? i mean the flywheel goes along the trigger coil and makes
spark right???  i am stumped as to what it would be and dont feel like taking
it to the dealer quite yet.

anyone that could help would be greatly appreciated

thanks
chris

This may sound stupid but it sounds like
the ignition system is being grounded out some place.  If I am not mistakin
That is a normally open system so maybe you have a short/ bad ignition switch
ect.

Have you tryed mesuring the voltage with the trigger coil unplugged? I know
it's dumb question but it's rare for magnets to be the cuase unless the magnets
are broken or grounding out against the coil.

I did see s situation one time were water got into engine area and surface rust
built up on the coil.

Good luck.

Never argue with someone who knows more than you. They will make you look like
an idiot.
