My electrical system is going crazy. My lights come on when I press the brakes, when i turn on my blinker it goes really fast and my clock light blinks with it. My blinker doesn't work when my lights are on, and this may or not be related but my temp gauge is messed up too. As soon as I turn my car on it will go all the way to the right past 260 then it will read what it is supposed to then jump to the right again. I'm thinking it might be a ground problem but I was just wondering if anyone has ever heard of anything like this before?

 

Check your ground connection near the battery, these are known to loosen and cause problems.
