Thanks John and Peter, for your analysis and replies. OK, first thing done. I configured my OBDIIC&C to show ELD this morning. Key on, everything else off: fluctuating between 5-6. Driving down the road with headlights on: fluctuating between 23-26. In autostop mode with headlights on, fluctuating between 20-22. I don't know if that is appropriate behavior, or not. This afternoon, on the drive home, I'll disconnect the white 3 wire connector on top of the ELD to see what happens. I assume that is sufficient for Peter's test, but perhaps I need to fully remove the ELD?
