1988 Accord Fuel gauge + electrics

[Xaisk]

Alright I figured out why the starter would'nt work on my 1988 Accord. The engine block to frame ground wire was attached to a bolt on the thermometer casing. It had gotten covered in gunk and a ground signal wasnt getting through. I took it off, cleaned it, filed both ends and it works like a charm. has been for the past 3 days.

Now some more problems.

I took the drivers side fuse cluster down looking for the main relay. (for the last problem) and apparently I crossed wires or something that shouldnt be crossed.
Ive yet to go fix it but the problems are: The left turn signal goes double speed. the right side door light doesnt come on when its open. Ive yet to go check it but im going to today. should be fixed by redoing the wires.

Now the main problem. The fuel gauge reading doesnt fall below half.
I dropped the tank and cleaned the tank out, and cleaned the crud off of the fuel tank sensor. I put it back in and the sensor will go up to full tank, and drop down to half, but wont go any lower. its actually just slightly above half.
Why could this be happening?

By the way, if any mods read this my previous 2 threads can be unstickied.

They are called. 1988 Start Relay, and 1988 main fuse I believe.

So I also found that the rear right Brake Light isnt coming on either...
I checked the fuses today and found that 2 fuses. (radio and something else) were 7.5 amps and shoulda been 10. I replaced embut nothing was changed. the 7.5 fuses are in fine condition as well so I saved em.

What could the issue be? I went down into the drivers dash and pulled down the main fuse cluster and unplugged em n stuff, but I replugged everything in exactly the way it was. I noticed 1 black plug that wasnt plugged in, but it was already unplugged and everything was working fine before. Plz some help would be amazing since I am a novice with electrics...
