Do not attempt to repairit.VDO Instrument PanelRG10606B –UN–20OCT99Following is a brief description of the components on theinstrument (gauge) panel:A—Oil Pressure Gauge - The oil pressure gaugeindicates engine oil pressure.B—Coolant Temperature Gauge - The coolanttemperature gauge indicates coolant temperature.C—Tachometer - The tachometer indicates engine speedin hundreds of revolutions per minute (rpm).A—Oil Pressure GaugeB—Coolant Temperature GaugeC—TachometerD—Engine Control LightE—Preheater LightF—Fuel Level LightG—Battery LightH—Oil Pressure LightI—Coolant Temperature LightJ—Key/Start SwitchK—Hour MeterThe engine control system consists of the following:D—Engine Control Light - The engine control lightilluminates after the engine has started and oil pressure isup to specification. The light indicates that the engineprotection circuitry is activated.E—Preheater Light - The preheater light illuminateswhen the key is turned to the bulb test position (positionI).
