Re: HELP: ****sche 944 no spark

The spark is actually produced by taking away the 12v.  The DMA will ground

the coil for every time it needs to spark.  You can try testing the coil
by 
using Clark's website suggestion.  I tried this and I thought I would see 
more of a spark.  I actually had a hard time seeing the spark so I had to 
move the coil and battery into a dark room like a walk in closet to see
it.

My guess is if your coil measures good it probably is good.  Do you know 
about Clark's web site.  Here is a link to the troubleshooting section on 
"No Spark": http://www.clarks-garage.com/
go to "Garage Shop Manual" click

on "T" for Troubleshooting and then on "TS-01"

BTW my problem was a bad ignition switch.
