EHA numbers , need a reference
I know this is all in the archives but I got bogged down trying to decipher it. On the M103 with CISE someone please fill in the blanks.
Key On Engine Off; EHA current = 20 ma Duty cycle = 70% Engine running (warm) EHA = _______ EHA wit O2 unplugged = 0.00 ma EHA ma under acceleration = ______ EHA ma on deceleration = -62 ma (is this correct?) Duty cycle = 45-50% w no fixed numbers |

Cap'n - I am going to run it over to C. Potts at lunch and get him to resolve it. I am not going to have time for the remainder of the week.
In the CD there is a sheet in there that tells you what the "fault" is at the different duty cycle %'ages. Example is 70% has something to do with the "signal" from the fuel pump relay.

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 I have never tested under acceleration, but I will assume it will be the same as above (do not quote me on this).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)
