Truck in question is a 94 K2500 Suburban with a 6.5 Diesel. No tach. The speedo works once in a while, truck goes over a bump it stops, goes over another bump it works. The OPG, Fuel, Coolant, Volt all work. I took it appart once and noticed the PCB (Printed Circuit Board) has worn contacts on it, can I re-tin it myself? I would prefer getting a new one. Who would sell one online or is this a dealer only item?



Thanks

Matt
