Plastimo Fuel Sender problems ???
I have the above fitted on my fuel tank, vertical type. My boat is mainly afloat and continuously bobbing around.
When the battery is isolated the fuel gauge shows empty, when the battery is on the fuel gauge is showing full. The tank is half full and I have removed the sender to ensure the float is not jammed. The system has worked for the past 3 years without problem.
Is there an easy way to test the sender to see if this has failed.
