1996-up, V4, V6, V8. 60 degree and 90 degree engines, with carbuators.
Two guages, a 2 inch with 4 LEDs or 3 inch guage with an analog tach. Logic is in guage.
No Oil light= No oil being delivered.
Low Oil light= Oil in tank down to about 1/4 tank.
Water Temp light= Overheat. ONLY SENSOR THAT WILL SET S.L.O.W. The other sensors are block from setting S.L.O.W/ by blocking diode in engine harness.
Check engine light= Fuel restriction. ONLY on V6 and V8
Key on, system will self test, all lights on then off in sequence, horn will sound 1/2 second.
Problems when engine running, will sound horn for 10 seconds and light the appropriate LED.
Wire colors.
No Oil sensor= tan yellow/stripe. Sensor located on VRO/OMS pump.
Low Oil sensor= Tan black/stripe. Sensor located in oil tank.
Temp sensor= Tan. 6 inch Pig tail on sensor may have a stripe to id working Temp.
Sensor located on cylinders heads.
Check engine= Tan orange/stripe Sensor located on VST on 60 degree engines.
Diagonostics.
Key on, engine off, ground each sensor wire to engine block, when grounded LED will come on. Horn WILL NOT beep. If LEDs donot light up check for power at tach. If battery voltage present replace tach.
Key on, engine running at idle. Grounding sensor wire, will light the appropriate LED and horn sounds for 30 seconds.
