Has anyone with an ammeter installed measured their engine's actual current draw (controller, injectors, plugs, fuel pump) with everything but the engine shut down, and the alternator offline? IIRC, Bernie Kerr once did a battery duration test & discontinued after ~40 minutes, but I don't recall seeing any actual current measurements.

Thanks,

Charlie
