My measurements more or less agree with Charlie's. =C2= =A0The main fuel pump will vary its draw depending upon the back pressure f= rom about 4 amps to more than 10 (guess how I know it goes higher than 10 i= f the filter gets clogged.... )

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

Thanks,
