3.
Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
4.
Disconnect the yellow wire (to the oil level sensor) from the terminal on the low oil warning light. Using an alligator
clip jumper wire, connect the low oil warning light terminal to the vehicle frame. Connect the red (+) battery cable
to the positive (+) battery post, then attach the black (–) cable to the negative (–) battery post.
5.
Turn the key switch ON. The low oil warning light should illuminate. If it does not, check continuity of the yellow
wire that connects the key switch to the low oil warning light. If there is no continuity in the wire, replace the wire.
Then test the key switch.
See Key Switch (Starter Circuit) on page 12-14.
If the yellow wire and the key
switch test okay, then replace the low oil warning light.
