the 4 gauges off to the side on my 88 fuel oil temp and volts in the morning when its cooler dont work. in the afternoon they are fine. i took the cluster out and cleaned the circuit board where the connectors go in i cleaned the wires and even spread them a little. now when they dont work sometimes all it takes is a little tap on the the top of the lens and they work. could i be looking at a loose connection with those gauges and not the cluster connections? any help is appreciated thanks.
