RELAY-SWITCH LATCH AND TERMINAL BOARD
-
ASSEMBLY
1. If only relay-switch was replaced, solder red lead
(shortened by approximately 3 inches) of new relay
assembly to red lead from terminal board, and tape
this splice.
2. If only terminal board was replaced, resolder three
leads to new terminal board
-
solder red lead to
terminal No. 1, solder tan with yellow-stripe lead to
terminal No. 2, and solder black lead to terminal No.
3. Terminal identification shown in Fig. 12A-7.
3. If both terminal board and relay assemblies were
replaced, resolder two motor leads to new relay and
resolder three leads to new terminal board.
4. Slide terminal board into wiper housing, being
careful to position terminal board resistor lead as
shown in Fig. 12A-7.
NOTE: With relay-switch replaced in housing and
washer pump reinstalled, the relay-switch plastic housing
applies pressure against resistor lead to form a positive
ground connection to wiper housing. Without this
resistor ground, the wiper probably would have excessive
speed in high while having a normal low speed.
5. Position relay-switch in housing.
CAUTION: Be very careful to route lea& in such a
manner as to avoid having them pinched between relay
and wiper housing.
6. Install relay-switch mounting screw (Fig. 12A-6).
7. Assembly washer pump to wiper, being careful that
ground strap is properly connected.
