1983 Ford Club Wagon with 351 ci. Front/rear
My front gas tank quite indicating level
to gas gauge last year. 2 months ago my
rear tank quit showing gas level on fuel gauge.
Dual gas tank with seletor switch/
gas gauge shows empty always now for front and rear.
Selector switch is new and good.
tested resistance between switch and
gas gauge/instrument panel good.
Now I need to check fuel sender units at
1983 Ford body chassis electric Shop manuel
tells how to check calibration of fuel gauge
It says to disconnect wiring at sender unit, connect
"22 ohm resistor" to the lead wire and then ground these.
Turn ignition on and gauge should indicate mid scale
on the gas gauge. If it shows mid gauge then the
sending unit in the tank is bad. If the gauge still shows
empty then there is a problem between the sender unit
and the gauge.
My question...the "22 ohm resistor". can I go to
radio shack, ask for a 22 ohm resistor, put alligator
clips on it and use that for this test...
