About to dive into behind the dash panel and replace 2 tach’s and also investigate possible earthing problems of my volt gauges. Can anyone tell me if the Buss Bar is an easy find behind the dash panel in a 97 450DA?
 
It's an extremely easy find on a 97 400DA but I cannot say how similar your 450 will be. Mine was directly behind the access panel, below the fuse block.

Thank you, heading down to boat over weekend, hopefully that easy to find.

lay on the floor at the helm open the access hatch and look up... and I had to replace one of my volt gauges (so they can go bad)
 
Excellent, thank you. I am hoping it’s just a bad earth. On last trip out, both were reading exactly as they should when underway, 13 plus volts, then the day later on trip home, both reading around 12v’s. did all other checks, everything charging as they should, just gauges reading around 12v’s. will start checking earthing first. I doubt whether both gauges would go at same time.
 
Earth first... I take that as your ground?

What do they call the negative bus on the space station? Can't be ground. Can't be earth. Hmmmm.... I guess that rules out a Honda portable up there.
And winter has just started. This could get wierd.
