H: Oil Indicator Does Not GO Out After Engine Is Running

1. Check oil level and oil pressure with a mechanical gage.

^ If oil level and oil pressure are OK, go to step

^ If oil level and oil pressure are not OK, see Engine.

2. With the Ignition Switch in RUN, disconnect the Engine Oil Pressure Switch and observe the OIL Indicator.

^ If the OIL Indicator is now out, replace the Engine Oil Pressure Switch.

^ If the OIL Indicator is still on, check the TAN (31) wire for a short to ground (see schematic).
