I've been experiencing an erratic engine rpm indication on my Plasma II+ system. It drives the top/right plugs and a Slick 4371 drives the bottom/left plugs on the O-360 in my -7A. The LSE tach is displayed on my G3X and the magneto rpm displays on a GRT EIS-4000 that I left some items connected to after I shifted most to the G3X.
The magneto tach is steady as a rock and LSE tach on the G3X jumps all over the place. The LSE tach was similarly steady until about 6 months ago.
I've cleaned and reconnected the 15 pin connector to the LSE several times. Has anyone else experienced similar issues that can offer some suggestions on how to correct it? Time in service is about 1300 hrs. over the past 12 years.
Thanks, Mike
