> 12V. Maybe a series resistor would do it. I was wondering about that. I opened up a 12v gauge and a 6v gauge tonight. The 12v gauge has an internal resistor labelled as 68kOhms, and measures as 71k. (This is o.k. to measure -- one end of the resistor is connected to the + input of the gauge, so I don't have some other current path in parallel to reduce the apparent resistance of this component.) The 6v gauge's internal resistor appears to be unlabelled, but measures at 28kOhms. Half the voltage, ~half the resistance, same current. One thing, though -- the 12v gauge has a little coil of windings of fine wire in its circuit -- it's outside of the heart of the gauge, the magnets/coil(s) on which the needle rides. It shouldn't have any direct effect on the magnetic action that drives the needle. I can't imagine that it's significantly resistive. What would an inductor do in this simple circuit? I'll have to look more closely at the gauge in good light to determine whether this extra coil in the 12v gauge is simply one of several components in series, or whether it's slightly more complicated than that. -Greg ------------------------------------------------------------------- Search old messages on the Web!
