Re: Sending unit on fuel cell
Do you have an ohm meter ?.
With the sending unit out of the tank you then set the meter to the ohms scale and then connect one test lead to the ground of the sending unit and the other test lead to the terminal on the sending unit that would go forward towards the fuel gauge.
With the float hanging all the way down (like it would be with no fuel in the fuel cell) the meter should read close to 0 ohms and when the float is in the full up position (like it would be when the fuel cel is full) it should read close to 90 ohms. With the float arm halfway between up and down it should read somewhere around 45 ohms.
If you get these readings, then you need a 0 ohm empty to 90 ohm full gauge to work with what you have.
