Just a curiosity: I don't see anymore those handy amp-meters with a
central zero. I have one in my boat that occasionally sticks and
wonder whether I can find a spare.

It's sort of hard to see but it is the one in the upper right; the
rest position of the pointer is at -45 deg.

Auto-spares shops usually stock these meters.
===========================================

The old style zero center ammeters are not very desirable in my
opinion unless mounted very close to your batteries, or it has an
external shunt. Without a shunt it is necessary to run a high current
wire (large) all the way to the meter and back to your battery/engine
area. Better to get one of the new digital ammeters (with shunt) that
reads both positive and negative flow.
