    Hello!, looking for help!!! I have a 1989 377 Peterbilt with digital dash -- Tach, speedo, fuel, water temp, oil pressure, etc... when you turn the key on the dash just flashes on and off.
    No readings what so ever, just flashing. I had the numbers off the cluster and the control box, but seem to have missed placed it at the moment. If I need to I can pull them out
    again and get the info off the back. Any ideas what might be going on? If it is the cluster its self is there any place that repairs these, or is the best option to get a mechanical
    dash comlete out of a salvage yard and hook it up? Seems like all the wires would be there for the swap. I currently have a mechanical oil pressure gauge and water temp hooked
    up, but these are the only 2 gauge I have right now that work. Anyone know about this??? THANKS!
