While flying yesterday I lost my tach signal to my AFS-2500 engine monitor. I felt a light shutter when it happened and noticed I had no tach reading. I assumed it was a loose wire from my right P-mag to the AFS module for tach input. I checked those connections today and couldn't find anything out of place so I buttoned up the cowl and started the engine. It started fine but I still didn't have a tach signal...
I did a "mag" check and discovered the engine would shut down while attempting to run on the right P-mag. It would not run via the right P-mag on ships power or on its own internal produced power. Since the tach is fed from the right P-mag...I think the connection is just fine between the Pmag and engine monitor but the Pmag is not sending out any signal...
I have a call into Emagair but they haven't gotten back to me. I have not installed this system so I am a but lost when it comes to troubleshooting.
I figure if the engine was running (via the left p-mag) then the gear in the right p-mag would be spinning enough to produce internal power in that mag and should run....no? Makes me think perhaps the gear has malfunctioned?
On the other hand....even if the gear was not even installed....would it not produce power via ships power? Maybe not because it wouldn't know the timing. I suppose I am leaning towards a bad gear but I am just troubleshooting without any real knowledge of how this thing works.
What do the experts think?
