I have a Faria 4 in 1 gauge on my boat and everything works on it except the volt gauge. My dealer says the gauge is probably bad and needs to be replaced. My question is if the gauge is bad, why do the other gauges on it work correctly. This is a new boat bought in early summer and the volt meter has never worked. I called the dealer and they said they could fixit and to bring it back. I live almost 2 hours from dealer and told them they could look at it in the fall, I have boating to do! Took it back to winterize and they checked it. They said they "wiggled" it and worked for a second. That is how is was "determined" to be a bad gauge. Confused and any help is greatly appreciated.
