Hi everyone,

I have a GlaStar with with an aerosance fadec that went bad. To get flying again I am pulling the fadec (which covers both fuel injection and ignition) out, as well as the VM1000 engine monitor because it only works with the fadec. The new engine monitor only has a main power in, and uses that to determine system voltage.

From my old setup, I have 2 switches on the dash that switch voltage and amperage displays from system 1 to system 2. I am trying to figure out how to make use of these with my new engine monitor.

Is it crazy to think I could have a SPDT (on-on) switch with 2 battery in’s (the 2 load positions) and 1 output that flows through a capacitor then into the engine monitor to switch voltages? I realize that switch is made for 1 battery in and 2 load outs, can I run it backwards? In my mind, the capacitor would have enough stored energy to keep the engine monitor running during the system 1/2 switch.

I’m a newb with electricity so be gentle Smile
