again with the door in the breakout (negative 3°) position. In a dual-door application, both doors can be
tested at the same time in the closed position. However, the doors must be tested individually when
checking switch continuity with the doors in the breakout (negative 3°) position.
c. ENSURE door is in the closed position.
d. Using a multimeter, CHECK continuity between TB3 terminals 9 and 10, and
ENSURE there is continuity.
e. PUSH door in the breakout direction, and HOLD door at approximately the negative
3° position.
