Jim,
That 11 amps would sound more reasonable to me if you can say that the
base K2 is being powered separately, but I would expect something closer
to 50% efficiency rather than 66%.

Thanks Bob,
That makes me feel a bit better. I'm still going to remeasure it with a newer
meter and see if the measurements check.

At 13.8 volts, 11amps is about 152 watts input. 100/152 = .658 * 100 for about
66% efficiency.
All in all , looks about right to me. AKA - I wouldn't be concerned.
