Hi - I've got a 1990 GMC 5.7L 4x2 pickup. When I turn it on, the temp gauge goes all the way to the left and stays there (and when I turn it off, it goes all the way to the right). Also, when I put my turn signals on, the voltmeter moves left to right to left to right with the ticking of the lights. I'm guessing this is a crazy electrical thing, but where exactly under the hood should I be looking?
