2. Switch Side Connector Circuit

Remove the switch connector, and check continuity
and voltage between the switch connector terminals.

(Connect the (+) terminal of the battery to 9 D-5 and
the (–) terminal to 5  D-5 .)

5  D-5 - 6  D-5 . . . .  Continuity

5  D-5 - 8  D-5 . . . .  Continuity

(Then, ground 3  D-5 .)

6  D-5 . . . .  Current flow for approx. 1 second

(Disconnect the ground of 3  D-5 , and ground 
4 D-5 .)

8  D-5 . . . .  Current flow for approx. 1 second
