Sender unit

[Jon]

Hi peeps 

Can anyone tell me what ohms the Sierra sender unit should read please. 

[niduncan]

I took these measurements back in 2004, hope they help.

I have a fuel sender on the table in front of me. The Ohms between the pins (numbered as above) and the earth post are as follows:-

Pin1 float at top (full) = 21
Pin1 float at bottom (empty) = 176
Pin2 top = 200
Pin2 bottom = 67
Pin3 top = 183
Pin 3 bottom = 183

These "top" and "bottom" positions are with the float moved by hand and obviously out of the tank, and without the plug from the loom connected. Also the sender is an old one from the 1986 donor so the rheostat will have worn somewhat, never the less the values match niduncan's, more or less.
