I have a T206H and The POH says:
Current indication (AMPS) for both the main and standby batteries is provided at the bottom of the EIS bar (along the left margin of the MFD or PFD), labeled M BATT S. Main battery current is numerically displayed below the M. Main battery current greater than -1.5 amps is shown in white. Standby battery current is displayed numerically below the S. A positive current value (shown in white) indicates that the battery is charging. A negative current value (shown in amber) indicates that the battery is discharging. In the event the alternator is not functioning or the electrical load exceeds the output of the alternator, the main battery ammeter indicates the main battery discharge rate.
The part that confuses me is the one that says:
Main battery current greater than -1.5 amps is shown in white.
Does that means that when the number is negative but greater than -1.5 it is OK, because it is in white?
And after 40 minutes of flight in normal daytime operations I have a -1.0 in the M BATT amps but the M BUS volts remain 28.3. What does this mean?
