Some questions for the experts regarding some of the data above?

House load, no fuel pp, low beams = 3.2 amps - acceptable?
Fuel pump is drawing 3.9 to 4.0 amps - acceptable?
Stator unloaded VAC output has max deviation of 3 VAC - acceptable?
Ground cable to various frame points max resistance .2 ohms - acceptable?
Stator Vac INPUT, loaded A-B = 1.6, A-C = 1.8, B-C = 11.1 - normal, acceptable?

I read over here that

Does the FJR shed to ground via 1 or 2 AC phases or all 3? If so, could this explain why phase B-C at 11.1 vac is much higher than A-B or B-C?
