3. INSPECT TURN SIGNAL FLASHER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead to terminal 3.
(b) Connect the 2 turn signal light bulbs parallel to each other
to terminals 1 and 3, check that the bulbs flash.
HINT:
The turn signal lights should flash 60 or 120 times per min-
ute.
If one of the front or rear turn signal lights has an open cir-
cuit, the number of flashers will be more than 140 per min-
ute.
If operation is not as specified, replace the flasher.
