A friend purchased a 47 coupe with a SBC engine; IE, 12 volt system. Stated that the ampmeter moves very little & he is asking if the wire "thru the loop" behind the ampmeter needs to be cloth covered instead of plastic covered? Will that make a difference? Hope I have understood the question correctly. Thanks, EdB

The type of insulation will have no effect on the amp meter reading. 12 volt circuits use less current than 6 volt circuits, that may be why he is not seeing small movements in the ammeter. Tom

Even with 6-volts, when the battery is fully charged and the current regulator is operating correctly, there may be little or no movement of the ammeter. Leave the headlights on for about 15 minutes, start the engine and see if the ammeter moves. The type of insulation will have no affect. Richard This message was edited by 51f1 on 11-7-12 @ 8:46 AM

More voltage means less current (Ohm's Law), that is why 12 volt cars have smaller gauge wires. You can raise the ammeter reading by doubling the wire going thru the gauge loop.
