Circuit tester

1. Connect three dry cell batteries (1.5 V) in series.

NOTE:

• Use new dry-cell batteries.

• Using circuit tester, check that the initial voltage of a single dry-cell battery is 1.6 V or more. And also check that the voltage of three batteries in series is between 4.8 V and 5.2 V.

• For power supply, 5 V DC voltage source can also be used.

2. Connect the cell battery positive terminal to the connector terminal No. 3, and the cell battery negative terminal to the connector terminal No. 1.

3. With voltage applied, measure the voltage between connector terminals when the sensor link is moved slowly up and down.

Terminal No.	Inspection conditions	Standard
2 (+) — 1 (−)	Move the link within the operation range.	0.5 — 4.1 V

4. Replace the sensor assembly - headlight beam leveler if the inspection result is not within the standard value.
