Have a Mainship trawler with a single Yanmar STP-3STP 440 hp engine.It has a Yanmar i5601e engine gage that shows all the engine information oil pressure,oil temperature, rpm, battery voltage,etc it also shows network voltage my voltage reads about 10.2 - 10.9. I don't have the engine heater hooked up to the engine so i'm not getting a draw from there.Can anyone with this system on there boat tell me what the network voltage is when they are cruising.I have had 2 electrician look at this and they don't know why the reading is so low one guy was from Yanmar.
