Hi,

This is not the right way to measure current. By putting the meter
between the battery + post and the disconnected - battery cable, there
is no path for current to flow: it will not flow from the + post,
through the loads (radio, lights, mystery load), then through the meter
and back to the + post.*

Instead, connect the meter between the negative post and the negative
connector. The meter becomes part of the usual, normal current path and
will read the current as it flows from the battery +, the your loads,
and returns into the battery -.**

* Conventional current.
** What I said.
