Basically, it's what the sending unit does at it's low fuel postion. It's just a variable resistor and when the tank is empty, the resistance is zero....Basically, a short to ground.
Second opinions welcome though! I may have forgotten something in my old age.  |
Thanks Greg,
OK,
I grounded the power wire in the trunk(while plugged to the sending unit). Sure enough the gauge went over to empty
as soon as I touched the body. But, if grounded unplugged without the sending unit plugged in it does not go to full...grounded or not it just lays on full.
Now what?
BTW, Is there another ground besides the tail pan ground? Maybe one under the dash?
