Question about gauge cluster circuit boards

Thanks for the replies everyone! I feel it’s just too much of a coincidence with having the upholsterer working on it and that day my gauges don’t work. That’s why I figured it’s not dirty contacts or something. I will make sure that the circuit board is properly grounded and all the pins/ voltage regulator are intact and plugged in properly. If it helps narrow it down both turn signals and the cluster lights all work normal- literally it’s just the fuel and temp gauges that are totally dead all of a sudden. The circuit board replacement was not too expensive and I did buy an additional RTE voltage regulator to try also. I just wanted to make sure there wasn’t a third possible culprit I’m overlooking that I may need to order. Thanks again and please I appreciate any more comments/ suggestions!
