Re: Fuel sending unit test

Here is an illustration out of the 38-39 SM. The gauge gets battery voltage from the negative battery post connected to one terminal. The other gauge terminal has a wire that goes to the sender terminal. Ground is normally provided by the frame, body and tank connecting the battery positive post to the gauge mount and sender mounting flange. This type gauge does need a ground to operate so to do a bench test run a jumper wire from the bat pos terminal and connect it to both the sender and gauge mounting flanges.
The gauge terminal connections are important and may be marked as to which is battery and sender but if not, usually BUT NOT ALWAYS the diagrams show the proper hookup.
