ON a properly adjusted engine the running current value is a cycling current of positive & negative.

I made a harness for a digital multimeter and went for a test ride. The Key-On Engine-Off current was 20 mA and the overrun value -50 mA as expected. The current fluctuates between -4 and -5 mA at idle and shows a constant value of -10 when cruising above 50 mph (80 km/h) and also at WOT accelerating. There was no full load enrichment, the current was always -10 mA at normal driving conditions (with automatic transmission).
Questions:
A) Is the basic mixture setting too rich and is that why the EHA is always trying to lean out the mixture?
B) Is the lull load switch out of order or does the leaning effect override the full load enrichment.
C) How should I proceed?
