I'm using a 7805 regulator as the dash regulator (69 Barracuda) and it heats up after a while and stops working properly. The fuel, temp and oil pressure all show a lot lower than they should until I turn the car off and then turn it back on. The fuel gauge points have been pulled apart so it's not in the circuit anymore. I do have a small heatsink on the regulator with the proper heatsink compound. If I hit the regulator with freeze spray it starts to work properly for a while. I'm guessing I'm pulling too much current but I didn't think I'd have a problem. Any suggestions?
