Yes, a wiring diagram would be very helpful. Measured current flows through the ammeter. This means that the ammeter must be wired in series as a part of the charging circuit between the battery and the alternator. If you wire it up in parallel, it will not work. If you wire a voltmeter up in parallel it will work perfectly.

If you had a sufficiently large ammeter, with a reading of say 200-0-200 then you could simply connect it between the battery terminal and the wire leading to the starter motor and alternator etc. This would show all charge and discharge including current flow through the starter while it operates. If you do this with a standard ammeter and then press the starter button the result will be smoke and/or sparks and fire.

Of course, if you are as stubborn as me and live in a place where IHC used Lucas equipment, then you have all the fun of Lucas 6 and 12 volt systems running positive Earth as per Farmall M, AM, AMD, AW-7 etc.
