I have an 88 yj with a 4.2. Recently my battery slid forward and the metal bracket that was supposed to keep it in place bumped the positive side of the battery. It hit right on the terminal and now it is melted a little bit and deformed. Now all my electric components are acting up. At times the windshield wipers go on by themselves, the radio will shut off, the dashboard lights up the two green arrows(not blinking) and the blue high beams light. At times everything will be working right, although most of the time something is wrong. Sometimes the lights on the dash will stay on after i turn the ignition off, sometimes they will turn off but all light up when i hit the brakes. The lights will not work during this, brake lights, headlights, turn signal, fourway, nothing will work. sometimes when i turn the ignition off the parking brake light will light up but will then turn off after i turn the key to on. engine wise the car is running like normal.
im lost on this so any help is appreciated
