Let me try to explain what I am suggesting.

You have two sets of power wires that feed the control boards. One is white and black and attaches to the control board at the top. The second is red and white and attaches at the bottom. White is neutral of course and Black and Red are the two legs of 120 VAC power. You can measure current draw by clamping your ammeter around the wires that feed the board, BUT it can potentially confuse the issue. The black and white power to the upper attachment will have the current of the number one compressor, and both fans on it. The red and white power on the lower attachment will have the compressor number 2 and high speed for the condensor fan on it.

The best place to measure the current to the compressor is on the wiring that comes from the board and goes to each compressor. That wiring only powers the compressor, no other loads.

Are you measuring current on the wiring coming the board from the coach, or on the wiring between the board and the compressor?

I am sorry I am having such a problem with the English language.
