Boat has lots of gauges, engine room, helm, Flybridge and a Maretron system that lets a PC or dedicated screen show gauges.
Problem is some do not work at all. And some read inaccurate
Engine room tachometer is mechanical and the cable is cut. helm and PC tachometer reading seems good.
Engine room oil pressure is mechanical and seems to be the only accurate reading on boat, helms and PC read real low.
Engine room water temp is accurate but rest of gauges read too low.
There are several disconnected senders on the engine, would these be for me or a mechanic to check with an ohm meter? They seem to be on currently un-gauged items like fuel pressure. Wondering how I would know what a good or bad reading is, could possibly check one engine against the other if I am trouble shooting? Would like to label them with expected reading.
How do I go from where I am now to having trust worthy results at each location?
