[Electric Boats] Chinese panel meters

 

FYI.  I had to replace two of the DC voltage meters in my helm instrumentation panel. 
One of the DC 12 volt battery meters became intermittent and then just went south. The other whole pack voltage meter failure was my fault because though the spec said it could read up to 90 volts it needed to be powered by a separate 5 to 30 volt supply. So I bought two new meters with the same size display as the working ones. Including a 30 to 90 volt meter to read the whole battery pack voltage display that used just two wires (30 to 90 volt) for power and display. Thought it would be a quick replacement and rewire but, found out the outside case dimensions of both replacement meters were just a little to large to be direct replacements and so required some judicious trimming of the panel they were going to be mounted in.  So if you do order panel meters from different sources with the same display size be aware outside dimensions may not be exactly the same.
