I've been enjoying my dual AFS 5600's over the past 70 hours in the RV 10. Along the way, I've noticed the occasional erratic RPM indication. The indication may show high above redline and then a second later, too low. Aural alarms get the BP raised but the actual engine RPM itself is not changing at all leading me to believe it's a sensor or wiring issue. Upon inspection under the cowl, the only indication of something out of place was the black RPM sensor cylinder was loose within the red anodized housing that was screwed into the magneto. That was corrected with RTV and I thought the problem was solved until today when I noticed another erratic reading. Inspection of the sensor revealed it was snug. Has anyone experienced this? Faulty sensor ? I checked continuity of the wires and everything checks out although the unpredictable nature of the problem may indicate a loose connection somewhere. Ideas?
