Some current accounting: NHW11

I just figured out the rough efficiency of the DC-DC but it's based on the headlights being 55 watts each.

As per the Graham scanner showing ~300V Low beams draw @ .51 Amps that's 153 watts. 55 x 2 = 110 watts leaving 43 extra watts. That works out to ~72% efficiency.

Other electrical loads. 2003 NHW11.
Running lights: .12 A / 36 watts
Headlights: .57 A / 171 watts high beams .51 A / 153 watts low beams.
Brake lights: .37 A / 111 watts
Rear defrost 1 A / 300 watts
Fan setting in amps: 1) .21 / 63 watts 2) .34 / 102 watts 3) .52 / 156 watts 4) .65 / 195 watts
Steering draws about 1A / 300 watts only while turning wheel, stopped, on gravel.
