How much doe repairs usually cost??

Like mentioned in my original post the tach meter will move up the rpm scale and peg out at 5000 rpm. I did not test any other of my gauges because they were in my working cluster in my truck. I was buying and installing a tach to add to my cluster. So I don't have the answer about the other gauges. The board member who offered me advice and info was DAVE of DND Trucks. Maybe you can send him a PM and ask him if he knows. Tach repairs quotes from several internet companies were between $300-500. (More than the tach was worth.) Good luck.
