I had an erratic gauge problem so I upgraded the power and ground to my MDC box. That fixed the erratic gauges, but I still don't have a working speedo or tach. All the other gauges and switches work perfectly, and the speedo isn't clogged. Has anyone had this problem and what fixed it. My motor is 310hp carbed so I don't think I have as many complicated systems to go bad. Any suggestions would be great.
