I'm new here, and I need some help! You see...

[BIG CTY]

...everytime I do something to my rustbucket I seem to mess something else up. But before I get into that, here is the post I put on the "Welcome" forum introducing myself. Now back to the issues

First, I put a new steering wheel on my bucket. I tightened it down too far, but I finally got it right - with one issue...the horn ALWAYS blows. So I disconnected it and straight wired a horn. Now my battery is dying. (My signal lights no longer cancel either, but I guess I have to live with that) Could it be that there is current being drawn from inside that d@mn steering wheel somewhere?

Also, I put in a brand new used bench seat from the junkyard in my bucket. After installing, the gas gauge stopped working. When I turn the key, it goes all the way past the "F." What in the he!! could that be? What should I check?

I'm sure there is more, but I'll stick to that for right now.... Help HELP!! Thanks in advance!
