This is a fun thing to mess with!
Has it been working?
Are you mechanical minded, able to do some testing?
Can you use a voltmeter. Any?
Do you play well with others?
If you sorta look thru the CJ 5 and 7 Forums, you will see that I I will assist you, send pics, diagrams whatever it takes to help you. Until you are tired of me!
Our 1st test will be near or on top of the fuel tank
Can you find a connector somewhere behind the drivers door--in front of the rear wheel(under your rig) Maybe more around the wheel area on a CJ 7. At this connector (just one wire), the wire continues on to the fuel tank. To the sending unit, on top.
To verify the wire, a small inspection mirror might let you see the top of the sender.
This is a EZ place to do a test--at the connector! Behind the door (but underneath)
Undo the connector, have a buddy watch the gauge inside--KEY MUST BE ON!
With the end of the wire coming from up front (the gauge end) USE A JUMPER WIRE and Ground it to a REALLY GOOD GROUND.I have really long jumpers, I go all the way back to the Negative battery post. You don't have to.I over kill things!
You have just fooled the gauge into thinking you have a full tank. Does the gauge rise to the top? Very important, this will show us what to look for next, as being the problem. And which end of the wire to chase out.
Problems? My neighbor has a '83, I may can take pics if needed.
Waitin' on you!
