Also check that the resistance changes smoothly when the float is moved from "E" to "F".

TERMINALS RESISTANCE CHART

Position	Resistance (Ω)
Sender (E)	200
Warning lamp	160
1/2	54.5
Sender (F)	8

CAUTION: If the height resistance Is not within specifications, replace the fuel sender as an assembly.
After completing this test, wipe the sender dry and reinstall it in the fuel tank.
