envi ronment). Turn knob controlling the inoperative
motor to 10. Give the steel gear or rubber wheel at the
end of the motor a turn with your fingers. If the motor
was frozen, motor will start spinning. Lubricate motor
with an electrical contact cleaner/lubricant.
G. Motor is defective. The motor can be tested by
touching the motor terminals with the posts of a 9-volt
battery. Before testing, disconnect any gears that are
connected in sequence to the motor. If the motor does
not run from battery power, it must be replaced.
H. The Voltage Regulator and/or the Potentiometer inside
the Control Box that governs the inoperative motor has
gone bad. Replace or send in for repair.
I If Ball Feed Motor, and above solutions don't work,
Relay Switch on circuit board may be bad. Replace.
J. If none of the above solutions work, the problem is
likely a short or bad component inside the Control Box.
Replace or send in for repair.
15. PROBLEM
A motor runs, but does not change speed when the knob on
the Control Box is turned.
SOLUTIONS
A. If all motors run at top speed, check that the wires
inside the Control Box that connect the Potentiometer
Circuit Board to the Main Circuit Board are plugged in
securely. Red wire goes to the #1 terminal.
B. See Solution 14H.
16. PROBLEM
Turning a knob on the Control Box affects a motor other
than the one the knob normally controls.
SOLUTIONS
A. See Solutions 14A & 14B.
B. Voltage Regulators inside Control Box are shorting
across each other. Insulator Pad must be between the
Voltage Regulators and the metal bottom of the
Control Box. Voltage Regulator Bracket must not be
contacting the leads of any two Voltage Regulators.
C. If turning the Oscillator Speed up causes Ball Speed
and Frequency to slow down and the Power Switch
light dims, the Circuit Board Brackets have scratched
the traces on the Circuit Board. Replace brackets with
insulated brackets available free from Newgy.
17. PROBLEM
All motors run slow.
SOLUTIONS
A. Be sure you are using the correct transformer.
B. Bridge Rectifier inside Control Box is bad. Replace.
BALL JAMS
18. PROBLEM
Balls jam inside the machine. Ball jams are normally
indicated by a squealing noise from the Control Box.
SOLUTIONS
A. See Solution 6A.
B. Using new or very dirty balls. The tacky finish on new
balls or the dirt on dirty balls creates excess friction as
the balls move through the robot. As the finish wears
off or the dirt is removed, there is less friction created.
C. Oversize, irregular, or out-of-round balls. Check the
D. Dented or cracked balls. Anytime balls jam, check to be
E. Foreign objects or loose parts in the ball feed path.

Discard any balls that do not pass easily through this
gauge. Avoid any balls that have a rough seam even if
they pass the ball gauge test. See page 11.
sure none of them get dented or cracked; otherwise,
those balls can cause additional jams. Ball denting may
also be caused by build-up of dirt on the Friction Block
and/or Ball Discharge Wheel. Periodically inspect
these parts.
Remove the Clear Front Cover and inspect for objects
that are preventing the Ball Pickup Wheel from turning
or balls from sliding up the ball channel. Also check
inside the robot head. Reattach any loose parts or
remove any foreign objects.
Worn or defective Ball Discharge Spring. Open the
robot head and inspect the back surface of the Ball
Discharge Spring for wear. Replace if any flat shiny
surface is found or the spring is otherwise defective.
This spring should be completely round with no flat
spots.
the ball feed channel may warp inward enough to keep
balls from moving easily upward. Remove the Front
Cover and while holding a known good ball (as tested
per Figure 14, 1) slide the ball up and down the ball
feed channel to verify that it does not hang up. If it
does, it is possible to warm the walls with a hair dryer
and carefully bend the walls apart at the restricted area
to increase the clearance.
Short inside Connector Cable causes the Jam Alarm in
the Control Box to activate. Replace Connector Cable.
See Solutions 3E, 3G, and 3I.
