I'm trying to troubleshoot the gauges. They both don't work, the port does nothing, the stbd moves very little.

i checked to make sure the gauges have power, they both do.

the sending units have been replaced.

any suggestions on where to look next? i find it hard to believe they both went bad at the same time. (they haven't worked since i bought the boat in 10-07)
 
Are they adjusted properly? Did you check operation when they were changed?
 
The wires come attached to the sending units but at some point you have a splice - make sure it's a good connection and also waterproof. I'd check the alignment of the sending units and the grounds at the gauges.
 
thanks, i never adjusted them or anything...how do you do that?
