I've got a ROTAX 912 experimental power plant and neither of my ignitions are working.  No spark at the sparkplugs.  Engine turns over at over 300 rpms and I checked the ignition switches from my RV12 panel to the ignitions module and they show grounded and ungrounded when I switch them off and on.  One thing I did was ohm out the "p-lead" ignition switch and when the switch is off, the wire is shorted to ground BUT when it the switch is on, the actual p-lead is at around 300 ohms to ground.  That sounds kind of low resistance.  I would have thought the resistance would have been on the order of several kilohms. 

Also what should be the voltage on the output of the generator to the electronic module.  I checked the heavy Mainteance Manual for the 912 but don't see any info on that.
