How It Works

If the engine oil pressure gets too low, the engine oil
pressure light illuminates and an audible alarm sounds.
If the battery charge becomes too low, the battery
charge indicator light illuminates.

Testing - Oil Pressure Light

Disconnect the wire harness plug from the light cluster.
Connect 12v (+) to the "1A" terminal and connect ground
(-) to the "1B" terminal. If the light does not illuminate
replace the light assembly (Fig. 0809).

Testing - Battery Charge Light

Connect 12v (+) to the "2A" terminal and connect ground
(-) to the "2B" terminal. If the light does not illuminate
replace the light assembly (Fig. 0809).
If indicator lights test OK, check the circuit wiring and
Oil Pressure Switch. The green wire from the voltage
regulator needs to have battery voltage to keep the light
from illuminating.
