I've been having trouble with the brake lights on my xj since I got it a few weeks back. The brake, dash, and hazard lights don't come on. I tried the fuse and discovered that the fuse kept blowing as soon as I turned power to it so then I tested the switch only to find that it was blown too. After checking the rear passenger side first I worked my way around to the driver side. I have pinned it to somewhere between the back and the dash on the driver side. This is my first attempt at anything like this, and now I've realized that, while I know how to look for the problem in theory, I'm not too sure what the problem looks like. Where or what does my short look like? All I can see is the bundle all wrapped up in electrical tape. Should I start unwinding it all the way down or might it a common problem for it to rub in a particular spot causing it to short?

I'm using my break at work to write this so don't mind the grammar.

 

The most common fuse breakers are Bad Grounds. idk where they are on an 89. bad those should be your first guesses all the ones you can find wire brush them and make sure there nice and tight.
