Oil Pressure Gauge
- Unplug sending unit wire. Battery voltage should be present between wire and ground with ignition on. If not, check fuse. On Challenger and Sapporo, connect a 100 ohm resistor between wire and ground. Gauge should indicate about 85 psi (6 kg/cm2 ).
- On all other models, connect a 14 volt, 1.4 watt bulb between connector terminal and ground. Bulb should light and gauge should read around 60 psi (4.2 kg/cm2 ). On all models, if gauges do not have psi marks, needle should point at the second of the 2 center marks.
