Engine running (idle) EHA = hovering around 0ma if duty cycle is set at 45 to 55%
If duty cyle set a little rich (hovering at 35 to 45%) EHA current will be hovering around -3.5 to 0 ma.
If duty cycle set a little lean (hovering at 55 to 65%) EHA current will be hovering around 0 to +3.5ma.
I have never tested under acceleration, but I will assume it will be the same as above (do not quote me on this).
No steady duty cycle numbers mean no faults (with engine running)
