This is my first post so I will try a question that has annoyed me since I bought the boat last Autumn.
On my Merry Fisher 655 the (VDO) fuel gauge has a switch that has to be held on to read the fuel level. This is fitted as standard it seem to all these boats as the circuit diagram shows the switch.
Why do I need to hold a switch to read the fuel level for 10 or so seconds, and if I wire it into the ignition switch as it is on a car so that I get a continuous reading when the engine is running, will it damage the gauge?
Don´t shoot the messenger Don. It is what it is. It is a choice Jeanneau have made in their systems design. Ask them I would say. I am sure they had reason to do it this way. But since you own your boat, you can modify all you want.
