Ernest,
With the engine running, one fuel pump, and the comm/GPS, my current draw is
13 amps.  2 fuel pumps i.e. take off is almost 17 amps.

 


Taking this and the numbers Rusty gave, then adding them all up and throwing in a pinch of guesswork, I get a potential nighttime budget of 50 amps, with the typical daytime running being closer to 33.  I'm thinking this can't be right.

EM/2 0.6A
EC/2  0.3A
Injectors/Coils 10A (@6000RPM)
Fuel Pump-1 6.5A
Fuel Pump-2 6.5A
EWP-1 5A
EWP-2 5A
Landing Lights 10A
LED Position Lights 3A
LED Cockpit Lighting 1A
Cockpit Circulation Fan 2A
Transponder 0.5A
Radio 1A
CD Player 0.3A
