I'm having an issue with my speedometer, temp gauge, and gas gage not working. The oil pressure gauge works, voltage gauge is fine, but not the rest. Gas gauge works when theres a quarter tank or below, between quarter and half it jumps, and half and up goes to full. Not a fuse, dont know where to start looking for problem. Thought I would be able to overlook this problem, but on Friday i recieved my first speeding ticket, and defective equipment to boot!! So this is something I really need to fix. Thanks!!

 

Did they went out at the same time or one by one ?
