Ampmeter into Voltmeter?

[Denvermike]

I've got a 66 Barracuda and don't really want to change any of the gauges. I've seen a lot of threads about removing the Ampmeter, no problem there. Couldn't you just hook "voltmeter" wires to the gauge? I know it will show movement to the positive when power is applied. I think you could cailbrate it way putting different voltages to it and marking the gauge with very small lines on both sides of zero. (so it looks the same on both sides)

redline gauge works in CA does conversion not sure what is actually changed

No, you actually have to change the METER itself. A Mopar ammeter is not a "real" meter, that is, it is simply a piece of ?brass? cut to a certain size, so that when large current goes through it, it generates a magnetic field. A piece of wire will do the same thing. The needle part, is just a simple needle on a pivot with a magnet which is deflected by this field.

If you hook an AMMETER across a voltage source, you have an effective DEAD SHORT

Some of these conversions involve an inexpensive Sunpro voltmeter, which you take apart and use the guts out of

Here's at least one thread on converting gauges from ammeter to voltmeter.
