Acronym meanings on back of gauges

[18Fiatsandcounting]

This question came up in the recent "Fuel gauge stays full" post a while ago, namely, what do the markings on the back of the gauges mean, like "BN" and "GN".

I don't know why I was so dense, but in a moment of clarity last night (doesn't happen often), I figured it out. It's completely obvious, it's the first letter of the color(s) for the wire that attaches to that terminal, in Italian of course.

For the tachometer:
BN = Bianco/Nero (white/black)
N = Nero (black)
AN = Azzurro/Nero (light blue/black)
GN = Giallo/Nero (yellow/black)
M = Marrone (brown)

And so on. Well, duh...

You've got this all wrong, Bryan.

BN = Batteri Negativo!
GN = Ga-rouNde!
N = Negativo!
AN = Alternatore Negativo!

No?

Today's Italian lesson is: Impulsi al minuto.

"Why is this important?" I hear you scoff.

Some Fiat tachs (8,000 rpm max.) are labeled on the back, "16,000 Imp." So, 8,000 rpm is 16,000 ignition pulses per minute in a 4 cylinder engine. 16,000 impulsi al minuto. 16,000 Imp.

Crafty little devils, those Italians.
