NSX V6-3.0L DOHC (VTEC) (1998)
Volt Meter Gauge: Description and Operation
When the ignition is in ON (II) or START (III), battery voltage is supplied through fuse 5 to the gauges in the gauge assembly.
The voltage meter is operated by a resistor and two perpendicular coils in series. When voltage is applied to the gauge, one coil generates a magnetic
field that cancels the permanent magnet field which returns the gauge to zero. The field generated by the other coil causes the permanent magnet rotor to
rotate and move the gauge needle. The resistor limits current flow through the gauge.
