Ammeter Question

I recently acquired a 1951 8N. The ammeter gauge is busted and I would like to replace it. The current gauge is a 60-0-60. I have seen others for 8N that are 20-0-20 and 30-0-30.

The tractor is 6 volt. Which one do I or should I use?
 
If I remember right the factory gauge was a 30-0-30 gauge and not a wire type as in 2 post for wires but a shunt type gauge
 
a 30-0-30 will give you an easier to read scale.. and if using a genny is all you need.

the 60-0-60 would WORK fine too.. just harder to get a precise reading due to scale size..

a 20-0-20 would LIKELY work, as you won't normally see charges over 20a for very long at all... the shunt in the meter should be fine for low duty cycle excursions.. etc..
 
Tex........the original N-ammeter was a "loop" feedthru (just stick the wire thru the loop) Modern replacement ammeters are 2-terminal and you must "cut" yer power wire to fit on the terminals. tip: iff'n the meter reads backwards, just exchange the 2-wires. Simple, eh?

Surprizingly enuff, ammeters don't care 6-or-12V, and really don't care positive (+) or negative (-) ground. But you care. Just as long as the meter needle show charge (+) when engine is running.

Don't sweat the ammeter full-scale reading, yer 6-volt genny ain't never gonna output 20-amps. (some 12V alternator can pump 135-amps, whoo-whoo) .......Dell, a 12v advocate for the right reasons
