SECTION 1
1. Remove resistors 131, 130, 133, 132 and replace
with four 3.3K ohm resistors.
2. Clip and lift the following pins: Fl 1-1, 5, 11, 13.
These pins should be clipped as close to the solder
pads on the board as possible, and the pins lifted only
enough to break the connection.
3. Install four lmfd 50-volt caps between the lifted pins
on F 11 with the ( +) side soldered to the lifted pins.
4. Solder four 1 OK ohm resistors to the lifted pins on
Fll.
5. Connect the free ends of the four lOK resistors
connected to F 11.
6. Install a 1 K ohm resistor between F 11 pins 3 + 4.
7. Solder a lOK ohm resistor to Fll pin 3.
8. Connect the free end of the resistor on F 11 pin 3 to the
common end of the four lOK resistors on F 1 1.
9. Connect the(+) end of a lmfd 50-volt cap to the
common end of the five lOK ohm resistors on F 1 1.
Connect the ( - ) end to ground.
10. Connect a 1000 pico farad cap between F 11 pin 3 and
ground.
SECTION 2
The following changes are needed on cocktail games only:
1. Remove resistors R83, 84, 85, 86, and replace with
3.3K ohm resistors.
2. Clip and lift the following pins on chip FlO 1, 5, 9,
11.
3. Install four lmfd 50-volt caps between the lifted pins
on F 10 and ground with the ( +) side soldered to the
lifted pins.
4. Solder four 1 OK ohm resistors to the lifted pins on
chip FlO.
5. Connect the free ends of the four lOK resistors on
chip FlO.
6. Install a 1 Kohm resistor between chip F 10 pins 3 + ,
4.
7. Connect a lOK ohm resistor to chip FlO pin 3.
Connect the other end to the common side of the four
1 OK ohm resistors on F 10.
8. Connect a 1000 pico farad cap between F 10 pin 3 and
ground.
9. Connect the (+) side of a lmfd 50-volt cap to the
common end of the five lOK ohm resistors on FlO.
Connect the (-) side to ground.
Symptom: Intermittent fire control and coin switch.
Solution: Change resistors R15, 117 and 120 from lK
ohms to 470 ohms.

"Battlezone" Handles
Symptom: Handles are breaking and coming apart.
Solution: Additional ribs were added to strengthen
them and new brass inserts were added to keep the handles
from coming apart. Contact your distributor for availability.
