How much current is drawn from an alternator to charge the battery? I ran my engine today, and with only the Dynon EFIS/EMS and the fuel pump operating, my ammeter (which is positioned at the alternator output) was reading 13 amps. This seems quite high to me. My battery was a bit low because I had been configuring stuff in the EFIS, so I'm wondering how much current should be expected for charging the battery?
When I turned on my radios, pitot heat and all the lights, the ammeter was showing up to 50 amps... this seems really high for a vfr airplane!!
