Post by pipedream on Sun Mar 26, 2017 8:38 pm

There are 2 of these in my dash, they have small pcb boards on the back but are not connected to anything.
Any idea what they are and should I worry about them not working[You must be registered and logged in to see this image.]

Yes - could be a volt meter.  How many wires come out the back,  and is it possible to trace where they go?

there is just a black and red wire about 2" long on the back that are not connected to anything, and no obviouse corresponding connection they may have been connected to.
I maybe should have tken a picture of the back

Could well be a volt meter if it does not have any control buttons.  If it was mine, I would remove it from the boat and connect it to a battery (black to neg, red to pos) and see what comes up on the display! For safety you could run it through a small in line fuse (1 amp).  If it does not work and you want a volt meter, there are plenty on Ebay for a few pound.

Should have said there are 2 voltage meters on the dash next to the oil pressure guages they all look original, though the boat was built for export Germany
