I've been trying to figure out why my thermostat gauge and fuel gauge hasn't been working right. I took the gauge cluster out and found that the laminated circuit board has a couple places that are burned out. Also it seems that the little square resistor board isn't allowing any voltage through. I haven't been able to find any replacement circuit boards for sale. does anyone know of any around or where to find them? It is the e7tf-10c956-A type. Am I able to use the e9tf newer style? made sure all the gauges work and have changed out the sending units. Thanks for any input or help on finding one.
