The electric pump assembly is mounted directly to
the reservoir. A permanently lubricated motor is cou-
pled to an impeller type pump. The pump and reser-
voir are serviced as separate assemblies.
OPERATION
WIPER SYSTEM
Move the control lever up to select the desired
wiper speed. Move the lever upward to the second
detent for LOW speed wiper operation, or to the
third detent for HIGH speed operation.
Use the intermittent wiper when weather condi-
tions make a single wiping cycle, with a variable
pause between cycles, desirable. Move the lever to
the DEL position, then select the delay interval by
turning the end of the lever. The delay can be regu-
lated from a maximum of approximately 18 ± 0.5 sec-
onds between cycles, to 1 ± 0.5 second.
The windshield wipers will only operate with the
ignition switch in the ACCESSORY or IGNITION
RUN position. The wiper circuit is protected against
over loads by a fuse in the fuse block and a thermal
breaker within the wiper motor. This protects the cir-
cuitry of the wiper system and the vehicle. The wiper
motor has permanent magnet fields.
Pulse wipe is accomplished by holding stalk lever
in the WASH position momentarily. The wiper blades
then sweep once or twice after the WASH at low
speed and then return to the previous wiper switch
mode.
The wiper system completes the wipe cycle when
the switch is turned OFF. The blades park in the
lowest portion of the wipe pattern.
Push down on the wiper lever to the mist position
to activate a single wipe to clear off road mist or
spray from a passing vehicle. As long as the lever is
held down, the wipers will continue to operate on low
speed.
WASHER SYSTEM
To use the washer, pull the stalk lever toward you
and hold while spray is desired. If the stalk lever is
pulled while in the delay range, the wiper will oper-
ate for two wipe cycles (±1) after the stalk lever is
released, and then resume the intermittent interval
previously selected.
The wash function can be accessed in the OFF
position of the wiper control switch. Pulling the
washer stalk lever rearward when the switch is in
the OFF position will operate the wipers and washer
motor pump continuously until the stalk lever is
released. Releasing the stalk lever will stop the
washer pump but the wipers will complete the cur-
rent wipe cycle followed by an average of two more
wipe cycles (±1) before the wipers park and the mod-
ule turns off.
Fluid, gravity fed from the reservoir, is forced by
the pump through rubber hoses to the hood mounted
nozzles which direct the fluid streams to the wind-
shield.
