I’m doubtful of that.

G'day Fellas.
Andrew has come to the rescue.
Thanks for the replies.
Cheers

I think the original ammeter that mounts in the switch/ammeter panel is mounted using bent over tabs.
I found a cheap ammeter that used a mounting bracket which screws to the back of the ammeter.
There isn't enough space in the switch panel for the bracket.
The Royal Enfield ammeter looks good but was to big for the hole.
still looking. 
cheers

6 Volt ammeters are 8 Amp, 12 Volt are 12 Amp. The ammeter doesn't care what voltage is applied.

Interesting. I suppose that those running 12V on our bikes, and modern bikes, run higher wattage bulbs. If all the bulbs on a 12V bike were the same wattage as those on a 6V bike, the deflection of a 12A ammeter would be very puny, since half as much current will be flowing. Were it not for higher wattage bulds, one could rationalize this as being the opposite.

I ended up fitting a Massey Ferguson ammeter. You don't get much needle deflection but it works and doesn't fall apart.

Richard, the 12V bikes use a higher wattage bulb but bear in mind the ammeter doesn't just read discharge. The alternators probably have a higher output than a generator.
And I reiterate, the voltage of the system has nothing to do with the ammeter, it reads current.

I fixed my problem with a digital volt meter, much more practical, if your not counting the rivets.
available on flee bay.

G'day Fellas.
The ammeter from Andrew arrived today. Posted in UK on the 3rd, here on the 12th WOW.
Looks so much better than the cheap plastic ones and was a really good price. Andrew even through in the O ring to go under it. Hope to get it in after I get the Cafe top end back on.
Thanks Andrew
Cheers

G'day Fellas.
Wow what a difference a good quality gauge makes. Just fitted it but not road tested yet. At idle (Boyer ignition) -2 amp, about 1500rpm 0, about 3000rpm +4 and h/light on high +2.
6v dynamo, DVR2 at 12 v, 12v ignition & lights. Will road test tomorrow.
Cheers
