1. Disconnect the negative battery cable..
2. Remove the auto leveling sensor..
3. Connect the three dry cell batteries (1.5 V) in a series.

4. Connect auto leveling sensor terminal A to the battery’s minus terminal, and terminal C to the battery’s plus terminal, and apply 4.5 V of voltage between terminals A and C.
5. Connect the tester as shown in the figure.
6. When slowly moving the link up and down, verify that the shift is linear while the voltage is 0.5 to 4.5 V.

If the voltage cannot be verified as indicated in the graph, replace the auto leveling sensor.
