Thanks Korkie. Which connections? There are 2 grey boxes under the dash with 2 plugs coming out of each. Those??

I can start both Cummins QSM-11's and I get a readout from my Cummins ED-4 C-Command digital gauges. But my tachs and 4-in-1's have no readout at all. Needles don't move. Any ideas?? Thanks, Jeff

My 4 in 1 gauges won't come on at all. Is this related?? My Cummins ED-4 digital gauges work but not my 4 in 1. Help!

I have a 48' Sea Ray with similar problem. Flip toggle to on for port and starboard and no reaction on my 4 big gauges (2 for tach and 2 are 4-in-1). I can start up both engines and then my digital readouts work and give me water temp, rpms, oil press, etc.) But still nothing on my main gauges...
