Connect switch as shown in figure 3T-12. Adjust current
draw until it is twice switch rating. Current reading on
ammeter should drop to zero within 15 seconds. If it
takes longer than 15 seconds for circuit breaker to open
(current reading drops to zero), replace wiper switch
assembly.
INTERMITTENT GOVERNOR " .
To check the intermittent governor accurately re-
quires electronic testing equipment. However, if the in-
termittent wipe cycle is not satisfactory, check related
components such as the motor, control switch, and con-
necting wires. If all components function properly, in-
stall a new governor.
The electronic governor assembly is contained in a
two-inch cube which is attached to an instrument panel
bracket adjacent to the wiper control switch. The 6-inch
governor lead plugs into the wiper control switch and
the shorter, 4-inch lead plugs into the instrument panel
harness (fig. 3T-13).

(3) Connect other ammeter test lead to blue wire
w/tracer terminal (low speed) of motor harness. Current
draw should be approximately one amp but not more
than three amps.
(4) Connect blue wire terminal (high speed). Cur-
rent draw should remain about the same. In either case,
current draw should not exceed three amps.
