If I understand correctly what you say, it is exactly what I meant. With
additional circuits, that means roughly 30 +/- 25 Watt lighting bulbs (that
is roughly 800 Watts), the energy consumption is considerably higher. Try to
follow me: 800 Watts, ca 37.5 Volts generator voltage, current (I) = output
(P) / voltage (U) = 800 / 37.5 = 21 A.

Now, the air-electric MG set is rated for 1,200 W, 37.5 V and 32 A
permanently. It is obvious that additional 21 Amps must cause trouble when
you start the car with all lights on, some control circuits on and a battery
which is not fully charged or has insufficient capacity. Also, additional
800 W for a 1,200 W engine, isn't it much?
