Since the diesel is a compression ignition engine, no electricity is required to run it
In the purest form of a diesel engine, yes. In the case of the RED A-03 engine, electricity is required to run it, as it is FADEC controlled. The engine power is controlled by electrically operated fuel injectors, and the power lever is redundant electric [rheostats]. Electric fuel pumps are also required to provide positive fuel pressure to the two engine high pressure pumps. Two pairs of airframe electric pumps (so four pumps total, though the engine can run with only one of those four operating. The engine has two alternators, and the airframe has two independent batteries.
I hope to be test flying the second prototype within the next few weeks....
