Was just curious what the lowest possible amp draw a Q will have, as Advance is recharging my battery as we speak, and I am soon to be driving the Q to my friends shop, a distance of approximately 5 miles, all on battery. I'll have a chase car in the event something happens, in order to give the battery more juice if need be. I was just curious though as to how many amps a Q draws while driving, with no radio, no heat going, no lights either.

Not something I've ever measured but probably under 12 amps depending rpm. Since the alternator only supplies 34 amps at cruise rpm.

Alternator field coil [0-5?], injectors [2-3], ignition coils [2-3], fuel pump [4-5], ecu, tcu, transmission solenoids, brake lights, interior lights.
