DESCRIPTION & OPERATION
Instrument cluster includes speedometer, fuel gauge and
temperature gauge. Fuel gauge has a built-in voltage limiter to keep
voltage supply to gauges at 7 volts. Some models may also have a
shunt-type ammeter, oil pressure gauge, tachometer, voltmeter and/or
turbo boost pressure gauge. Oil pressure gauge uses full battery
voltage. The tachometer operates by pulse feed.
