Tried cleaning a ground. Dash cluster messed up
NEVER MIND I BLEW A FUSE. PROBLEM FIXED.
Sorry.
No improvement on gas gauge.
Well I have a fuel gauge issue. So I tried to clean a ground. There is a ground near the top of the radiator support. It was not orange and black. It was white and black. Along with the battery negative, it was grounded to the unibody. The unibody was very rusted underneath the ground leads. Before I removed the leads all of my gauges worked except the fuel gauge was alway on empty. I had to remove the battery to get to it. It had an exterior bolt holding on the the battery wire and one beneath it holding the other ground wire against the unibody. I took them both off an sanded and wheeled the rust off. Initially when I put them back I put them TOGETHER (there were separated by a nut originally) both against the unibody. When I started the truck it ran funny and the gauges were messed up.
I went back and redid the way that it was originally. The little ground bolted against the unibody then the battery negative up against the nut and a secured with its own nut.
Well now my oil gauge reads high, my battery gauge reads nothing, gas is on 1/4 tank. I am not sure if the speedometer works. I am a little afraid to drive because the first time the engine seems to rev. Obviously I have messed up the ground somehow but it is back as it was when I removed it. I got the rust off to bare metal. I wheeled both O connectors on the wires.
I could use some guidance. Could I have broken the negative battery wire ground somewhere under the plastic? I bent the O end a little but it is on snug.
So my cluster is jacked. It is possible my speedometer no longer works. I hit the gas in park and the tach did not move. Maybe that is normal. Maybe I need to change the negative battery ground wire. I don't know how this could have caused such a major problem. The surface area is now a bare metal clean area.
Sorry.

Not that it matters but its just "body", not unibody, "unibody" is a type of vehicle substructure that doesn't use a full metal frame under the body, the body is used as part of the substructure
Rangers use a full frame
What year is this Ranger?
The ground at the front of the engine bay is just for the head lights and horn, and some relays, its important but wouldn't effect dash gauges
So there is something else going on
Check the battery terminal cables positive and negative clean and reattach
The main ground for the cab is from the larger negative battery cable, it runs to the engine, usually near starter motor, this is the ground for starter, alternator and cab
On the back of the engine's head, drivers side on V6, there will be a ground strap(woven bare metal) attached to head and to firewall, this is the main ground for all cab electrics
If engine starts then I would think the main ground is OK
So check the ground strap to make sure its there and clean
I can't see any "white/black" ground wires but don't know the year of Ranger, Black/white was a common ground wire color

Thank you. It was blown fuse. I tried to modify the post before anyone posted. I am having trouble finding the place where the fuel sender is grounded. I saw that some F150's are grounded near the top support of the radiator. There was a lot of rust so I cleaned it up. Sorry. It was a fuse. Its a 2000 3.0 4X4
That might be the ground for the sender. It may have improved a little.

Try in passenger side footwell
There will be an Inertia switch(fuel pump cutoff) just behind glove box on the firewall, can also be behind passenger kick panel
It will have a Pink/black wire coming out of it, this is the 12volts for fuel pump follow it and see if it joins yellow wire(sender) and any black wires, grounds, long shot, but not a no shot, lol
They would be grounded behind kick panel
On my 2000 Ranger diagram it shows sender is grounded at G200, but I don't have a reference for where that would be on the vehicle
That ground is also Spliced at S307

I will check. The one I cleaned up is the main one. The other one likely goes into the tail light harness and is grounded with the the tail light ground. I will check. I did get a little improvement with the cleaning up of the one in front. The gauge was sitting on E. Or below. But now it stays 3/16" above E. Used to only do that on a good day and only briefly.
