Is ther a test to see if my stewart warner oil gauge is working. Its 6v electrical in a 34 pickup with 59ab. Just got it running after 25 years and gauge shows no pressue. Sending unit is tough to get to, wanted to try this first. Thanks, Mark
One side of the gauge gets 6V power---the other side goes to the sender... ground the sender side ( quickly .. touch it to ground and remove it) ,,, if the needle moves the gauge is good...no movement-it's bad......make sure the wire going to the sender has continuity ( not broken).... jersey Skip
Might also be a good idea to use a test light or voltmeter to see if it's getting power.... ~ Paul aka "Tha Driver" Easy on the Giggle Cream!
