This control supplies DC current to clutch.
To check solid state control raise front

machine and use block to hold front
drive wheels off floor. Plug machine power
cord into properly grounded outlet. Turn
on drive-motor switch and depress clutch
switch lever. If clutch does not engage,
check voltages on octal socket. Voltage

Check for loose electrical connec-
tions (at terminal block, switch,
motor P.C. board and receptacle).

after being replaced, the gear motor
may be grounded or short circuited.
To
test motor for ground or short
circuit, first disconnect machine
power cord from electrical source
then disconnect motor lead Molex
connector from motor. Using ohm-
meter, check resistance between
each motor lead and the motor
frame. If readings are (con-
tinuity), the armature is grounded;
replace gear motor.
To check for shorted armature, use
ohmmeter to measure the resistance
between the motor leads.
If resist-
ance is 5 ohms or &, the armature
is short-circuited: replace gear
motor.
If motor runs at maximum speed (no
speed control), check leads
and
for open circuit between speed
potentiometer and the P.C. control
board. If no open circuit is found,
the control board may be faulty.
Erratic starting and stopping
of

erse motor could be due to a faulty
