I just flew my plane for the first time since December. I was at the hanger in late January for an oil and filter change, and I ran the engine up to temperature both before and after the oil change. My hobbs meter was showing about 1240 hours, and I have a photo of that indication. I take a picture with my phone before and after every flight. Today I went out to do some pattern work and dust off the old skill set, not to mention the aircraft. I was shocked to find the hobbs meter indicating to 2272 hours! This number actually adds up to the number of hours since I did the oil change. The plane was sitting with a battery charger connected all of the time.
I did notice something new when I got in the plane this morning. I heard an occasional click coming from the panel. It happened every few seconds with apparent regularity. I traced it to the hobbs meter and saw a little flag indicator changing on the left of the face. I didn’t build the airplane and thus have a limited understanding of the systems. I am considering that perhaps there is a oil pressure sensor that turns on the hobbs which has malfunctioned.
This seems like a pickle to be in. I need to fix the issue and somehow wind the hobbs back to where it was indicating TTSN engine and airframe.
I look forward to hearing anyones thoughts and experience with something like this.
