I have a 87 camaro, the problem i'm having on the inside is the fuel, rpm,oil, & battery gauges don't work. the fuel gauge stays on full when its empty, the rpm gauge jumps over to 7000 and stays there, the oil gauges stays on 60, and the batt gauge works when its running but shows a low charge with a new batt and alt. Fuse's are good on the inside of the car. Is there any other fuse's on the car?
