When check is not OK, refer to this column

Electrical
(continued)

4. Check motor brushes for the following:

a. Loose terminal screws.

b. Broken or misaligned brush springs.

c. Brushes binding in holders.

d. Broken leads.

e. Worn brushes.

f. Brush leads snagged on spring clip.

NOTE: The brushes do not wear at same
rate on both sides of motor. Check both
brushes.

4. Refer to page 21.

a. Tighten.

b. Replace broken spring and/or align

spring with brush

c. Clean brush holders. Remove carbon

with small cleaning brush. Align brush
leads with slot in brush holder to as-
sure free vertical brush movement.

d. Replace brushes

e. Replace brushes if less than 0.4”

(10 mm) long.

f. Correctly route the wires.

See page 21.

5. Check motor armature commutator for burn spots,

gouges and extreme roughness. Remove motor
cover and brush inspection plates to check. See
page 21.

5. Remove motor and have motor shop

resurface commutator if possible. See
page 26.

6. Check motor armature for shorts using armature

tester (growler) or perform motor test. See page
20.

6. Replace motor. See page 26.

7. Check leads from pressure transducer and motor

to motor control board (47) to be sure they are se-
curely fastened and properly mated.

7. Replace loose terminals; crimp to leads.

Be sure male terminal blades are straight
and firmly connected to mating part.

8. Check motor control board (47) by substituting with

a good board.

CAUTION: Do not perform this check until motor
armature is determined to be good. A bad motor
armature can burn out a good board.

8. Replace board. See page 27.

9. Check power supply cord (50). Disconnect black

and white power cord terminals; connect volt
meter to these leads. Plug in sprayer. Meter should
read 105–125 VAC. Unplug sprayer.

9. Replace power supply cord. See page

27.

10. Check ON/OFF switch (52). Disconnect the “L”

wire between motor control board (47) and switch
and connect volt meter between exposed terminal
switch and power cord’s white wire. Plug in
sprayer and turn ON. Meter should read 105–125
VAC. Turn off and unplug sprayer.

10. Replace ON/OFF switch. See page 27.

11. Check motor thermal cutout switch. Connect ohm-

meter between motor’s red leads. Meter should
read 1 ohm maximum.

11. Allow motor to cool. Correct cause of

overheating. If switch remains open after
motor cools, replace motor.

12. Check the transducer (29) by replacing it with a

new one.

12. Replace pressure transducer. See page

30.

13. Check pressure adjustment potentiometer (64) by

replacing it with a new one.
