  1. Measure the resistance across the sending unit terminals.
  2.  
  3. With the float in the "up" position, resistance should be 14-26 ohms.
  4.  
  5. With the float in the "down" position, resistance should be 214-226 ohms.
  6.  
  7. Resistance should increase and decrease gradually as the float arm is moved. If odd resistance readings are evident at any point in the movement, replace the sending unit.
