It is a bit of a mystery as to out how the engineers at MB decided on such a tenuous start/trigger signal supply to this obviously hungry load, maybe they reasoned that the duration of the demand was so short that it didn't matter... or perhaps they were intending the overall impedance to act as a sort of current limiting "ballast" of sorts.
