Oil gauge not working (1 Viewer)

[Lynopractor]

My 1974 FJ40 oil gauge is not working. Not sure about the steps to troubleshoot this one!? Also the battery gauge jumps quite a bit swinging back and forth as well. Just curious about any thoughts on these issues? Thanks

check to make sure the wire is on the sending unit.

As 3P said, check wire. Then sender. Thread below is an excellent source of info for gauges…

Clusters, Gauges, Speedo & Odo meters

There seems to be a lot of questions about Clusters, Gauges, Speedo and Odo meters, so I thought why not set up a page as a reference guide / database / knowledge center? Over time I collected a lot of pictures. I created a Gallery with all the photos I have, which you can see here...

You can ground the wire to test if you see action on the gauge. The needle should move up, but don't do it too long past seeing that it rises or you can damage the gauge. If that doesn't work, you'll need to pull the cluster and check connections/power to the gauge.
