MY AMP METER IS BAD ON MY 6VOLT NAA TRACTOR. I THINK IM RIGHT THAT THE METER DOESNT REALY MATTER ON THE VOLTGE. IS THAT CORRECT. THANKS
 



Volts are volts, a volt gauge does not care, or know what your system is. It's going to tell you how many volts the battery has.

I always use a volt meter, and not a amp gauge.

READ my reply above. How do you know it is a bad AMMETER? Most likely other issues like a bad battery or generator needs rebuilding. Email me if you want me to rebuild it. There is no polarity on the AMMETER. Original was an induction LOOP style with the wire running thru the loop and current was measured by induction. New aftermarket AMP gauges now have two screw terminals. You simply splice the wire, connect on end of the wire to one side and the other cut wire to the other screw terminal. If when running the charge shows on the negative side of the gauge, you simply reverse the wires on the terminals. BUT -don't buy any new parts until you know exactly what the true root cause is -read above post for details.

"There is no polarity on the AMMETER."

An ammeter IS a polarity sensitive device. Current flowing through in one direction gives + side indication, current flowing in opposite direction gives -- indication.

"If when running the charge shows on the negative side of the gauge, you simply reverse the wires on the terminals." Correct. That is because an ammeter has polarity.
 
It takes both amps AND volts to crank an engine. Without volts, you have nothing to "push" the amps through the circuit. Ever notice how many starters today are rated in watts or kilowatts? Watts is a unit measure of power, and watts is simply amps x volts. Without volts, you can't have any watts.
 
HEY TIM. THE GUAGE ITSELF IS BAD. PROBABLY ORIGINAL GUAGE. BROKEN NEEDLE, GLASS ALL MILKED UP. ITS CURRENTLY NOT HOOKED UP. PROOFMETER IS THE SAME WAY. GOT A NEW ONE YESTERDAY. TEMP AND OIL PRESSURE GUAGES WORKS. SUSPECT THEY HAVE BEEN REPLACED AT SOME TIME.
