Hi Folks.
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?

Hi Don,
That is so there is no permanent power onto your cable terminals on your tank sensor. It is a safety measure.

Thank you Marco for that information.
Please tell me more as I am an electronics engineer and I can't imagine why it is 'unsafe'.
Are you suggesting every car with a continually operating fuel gauge I have owned is unsafe? Why is it a problem on my boat?
I can only imagine that if I removed the plastic cover from the sensor and placed a spanner across it there might be a problem but I
would only think that would be a blown 1amp fuse.
Don.

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.

Sorry bad start Onyva.
I didn't mean to 'shoot the mesemger'.
My job was always was to understand why thing are as they are, not start to think about it when the aircraft had crashed.
I have modified it this morning as I think it should be. We will see if the boat is now less safe but as you quite rightly say it's my boat and it's by far the best boat I have had.
Now why did they put the oil filter just there ??
Don.
