4. With the yellow wire disconnected from terminal
No. 53 on the
wi@er motor, turn the ignition switch
and wiper switch to the on position and check volt-
age available to the wiper motor. There should be 12
volts available at the durple wire with a properly
charged battery.

with wiper linkage’detached. If wiper motor will ndt
run, disconnect connector at wiper motor and co?-
nect hot lead from battery to terminal No. 53 onwiper motor. If wiper motor runs, the wiper switch
is faulty or there is an break in the lead wire. If wiper
motor still will not run, remove and bench test.

Cleaning apd Inspection of PartsWith the ekception of electrical parts and bushings,
clean all components in a cleaning solvent.
1. Check irmatare windings for ground, or open
circuit. If
b ground or open circuit is evident, the
armature must be replaced. If the armature checks
out, the c
brushes should be 6.35 to 8.47 ounces. Spring pres-
sure of worn brushes should be at least 3.5 ounces.
In case of /ower spring pressure, replace springs.
3. Check blushes for wear and replace if necessary.
Minimum brush length should be
.24’inch.4. Check d$ven gear for wear and replace if neces-
sary.
