Voltage and amps

[procharger]

What should voltage read and amps read when flying at speed, amps hang around zero or plus one voltage around 13.6 with everything running ?? thanks

I looked at some of the older posts wondering if anything new to report on this subject?

That sounds about like mine.  Amps 0 or up/down a bit (more up).  Volts 13.5 or so.

Voltage is read from bus to ground, and it should be over 13.2 volts to less than 14.3. Heavy loads will lower the voltage because of the voltage drop effect.

 

Amperage is read on the positive battery lead in most aircraft installs, between the bus and the battery terminal. In flight, you want the amperage to be zero or positive. Positive means it is charging, negative means it is draining. On the ground, don't be surprised if there is a slow drain since you don't have a high enough RPM to charge.
