For you electricians familiar with the more classic Sea Ray cruisers, please help me out with a basic question: Should the voltage supplying the helm gauges be the same voltage as one measures at the house batteries when the ignition switch is on? Here’s the context. My port and starboard voltmeters on the helm consistently ready low (11-12.5V), even when the engines are running, and I’m trying to sort out what might cause this. Today, as I was bulk charging my house batteries, and they were reading about 15-15.5V. I removed my helm cover and measured the +/- at each voltmeter, port was 12.58V and starboard was 13.11V. This match the display of the voltmeters, respectively, so the voltmeters are ok. Should there be a 2-3V voltage drop between the house batteries and the helm?
