[FC] Fuel tank sending unit -

[J R Read]

Did you get any sort of answer?  I never saw one posted.

20ish years ago lclc did a tech session on sending units which I attended. 
While there is no way that I can remember all of it, I do recall that an EM 
(includes FCs) should range between 0 and 30 ohms on a meter.  With the unit 
which is out of the tank, you should be able to hook up the ohm meter and 
move the lever which holds the float to see what readings you get at various 
points.  Say... half way should be ~15 ohms as example.

It sounds as if you already know this stuff by the way your question was 
worded.

Perhaps you need to take a closer look at the rheostat to be certain that 
there are no broken wires in the coil?

Later, JR
