They seem to be short case Guy?, no good as stock for Gerry and the steel cars?

[Guy Mayers]

They're fine for either type of car Griff. I think Gerry has a few of these already for his tin cars.

Had one for a while! Just need to fit it sometime...

These gauges have been available for a couple of years now.

I've got one of the middle ones. The A112 Abarth oil temp font matches the 124 font, but no yellow English lettering.

[Guy Mayers]

Yes Griff, but it's downside up... I'm still reluctant to suggest that a 50 Amp gauge would survive the output of a modern Alfa alternator (I don't know enough about elecrtickery) and haven't connected mine up in case the smoke tries to escape.....

Guy

[Griff]

Guy, I think its probably safe to bet, that 120A plus would illuminate the 50A ammeter for a short period (about long enough to undo seat belt, open door, and bale out) before the conflagration really took hold!!!

[Stableblock]

You could fit it with a suitable shunt. A shunt is just a suitable resistance in parallel with the meter.

In this case if you wanted the meter to show full scale at 120A you would choose the resistance of the shunt so 50A went through the meter and 70A through the shunt. You would need to know the resistance of the meter to work out the resistance of the shunt but its not a difficult calculation. I haven't done this as I dont know the resistance of the meter but I suspect a short length of cable of manageable cross section with lugs on each end bolted to the terminals on the back of the meter would fit the bill. You'd need to rescale the meter or just rely on the deflection and OFC you'd need some fairly hefty cable to get the 120A to the dash without loosing too many volts along the way.

Maybe taking purism too far though.
