<![CDATA[Charging system oddities]]>Firstly, what a great airplane and I look forward to the improvements brought with creating the 114 being pushed back to the Bonanza and Baron. These are my favorite piston airplanes in MSFS.

I have noticed a couple odd things with the charging system. I will admit that I only noticed it on the latest update. I am on MSFS2020.

  1. With alternator off and discharging a while, it shows a positive number of amps on the bus on the tablet instead of a negative number. The positive number on the tablet does, however, correspond to the ammeter negative amount. Photo attached-

  2. After a discharge for a while (I let it get down to 10.8v) turning the alternator back on shows only about 1 or 2 amp charge on the ammeter, but a negative amp amount on the tablet that does not correspond at all to the ammeter. This is what clued me off as it took me several tries to get the engine started and a decent amount of cranking where it should have charged at a high rate right after start. Discharging the battery a bit and selecting alt on should have a similar effect of charging high rate then dropping off as the battery is topped up. Photo attached-

This is obviously a small detail but thought it may be worth mentioning 🙂

I suppose I've just left the nomenclature the same in my tablet for all my aircraft. As for your second observation, I'm not sure I see anything wrong here. It looks like the cockpit instrumentation is reading about 13A, accounting for parallax. I would expect a higher charging rate just after engine start at high RPM, but only if you had most of the aircraft systems turned off. If you have everything up and running like in this screenshot, the power has to come from somewhere, so there will not be as much excess power to charge the battery.
