Sending Unit (2 wire vs 3)

[coachhejl]

I have a 4 cycle Kymco Scooter. The sending unit is bad and deteriorated on it and the part cannot be found.

I have found some online that are generic with the same mm bolt patterns. May have to alter the float rod, but they come with 3 wires and mine is 2.

Can I just ignore one of the wires? I understand the third wire sometimes is the low fuel light.

How can you determine which one it is? Using multimeter and probe two wires and the two that gives different readings when rod goes up and down will tell me which two right?

I tried this once with an old sender unit I had. Could only get it to work from the half full, to full range. Or empty to half full.
Tried all sorts of variation of wires.
