Turn on battery. Turn on LP fuel valve. Turn on HP fuel valve. Make sure throttle is in idle position. Press and hold start button for 8 seconds, and you will have ignition, and a running engine. Check your pressures are correct, and the EGT is rising smoothly to operation range, along with the hydraulic temperatures. Make sure you turn the AC on, not for you, but for the electronics.
Interesting fact is the HP and LP fuel valves are motorised valves, they need power to change position. Thus, if you turn the battery off, the engine will not shut down, although most of the instrumentation supplied with battery power will go off. The AC powered stuff will still be on.
