Amp meter showing discharge?

This is in an old Chriscraft boat with a generator - voltage regulator system.

When I check voltage at the battery while running it shows a proper 14.5 volts.

I know that if I swap the wires on the amp meter posts it will show charge, but how can I be sure that is the problem?

NOTE: we had a less than stellar employee here at the shop while I was on an extended leave of absence so I am not sure if it is wired properly or not.....

Update:

Thanks Tim. There isn't a whole lot of load to put on this boat, all it has is running lights so it doesn't really produce much of a draw. I suppose I could wire in a load like a 12 volt motor..... and as far as my ability. You climb under the dash of a 60 year old boat and try and trace out the wiring... Vintage correct so alternator isn't an option. Thank you for your input.
