I previously sent the backup battery from my left SkyView screen into Dynon because it didn’t seem to be charging during the first few flights. They charged the battery and tested it and it was fine. They sent it back to me so I installed it tonight and ran the battery test on both screens. Both passed by powering the screens for 45 minutes (and new batteries should power the screens for more than 1 hour).
While the battery test was running, I replaced a couple of cable clamps in the engine compartment with non-cushion bowden clamps that hold the cable much more securely than the cushion clamps I was using before. This is the clamp for the oil cooler butterfly control cable.
I also replaced the cable clamp at the forward end of the alternate air door control cable.
Finally, I decided to pull and clean the fuel filter again. There was a surprising amount of gunk in the filter. Most of the volume was some sort of fuzzy material, but there was also a lot of dust and even one small metal particle. I redid the safety wire and installed it back in the airplane.
