Recently, my dashboard started smoking. Only gauge working is oil pressure. I unplugged just the largest plug which was the side where the board was hot in the back and no more smoking - Is this a ground problem? I have in the past noticed my speedometer and RPM gauge drop, but just momentarily. I have another used instrument cluster, but I don't want to ruin it, should I check the grounds, i.e where the speedometer/etc goes into the transmission??
Any help is greatly appreciated. Thanks
