1. MID SWITCH

1. Measure the resistance between connector terminals.

Preparation tool:

Circuit tester

Terminal No.	Inspection conditions		Standard
3 — 2	(UP) i/SET (DOWN)	All OFF	Approx. 1 M- or more
	(UP)	ON	Less than 1 -
	i/SET	ON	Approx. 1,000 -
	(DOWN)	ON	Approx. 3,700 -

2. Apply battery voltage between the connector terminals to check lighting condition of illumination inside the switch.

Terminal No.	Inspection conditions	Specification
4 (+) — 1 (−)	Apply battery voltage.	Light ON

3. Replace the MID switch if the inspection result is not within the standard value.

2. TRIP RESET SWITCH

1. Measure the resistance between connector terminals.

Preparation tool:

Circuit tester

Terminal No.	Inspection conditions	Standard
