GAME REPAIR
If you see that the thermal switch is good, check to
see that the coil and the diode on the coil are good.
Disconnect the coil and unsolder 1 side of the diode.
Do a resistance check to see that there is infinite
resistance in one direction. If there is no resistance
in either direction the diode is bad. If the diode is
bad, there is also a chance that the drive transistor
and / or fuse could be bad as well.
If the diode tests good, check to see the resistance
of the coil. It should measure approximately 3.8
ohms. This resistance will vary some depending on
the temperature of the coil. If the resistance is sig-
nificantly more or less, the coil should be replaced.
COIL REPLACEMENT
1. Remove the 2 bolts that hold the punching mech
cover in place.
2. Disconnect the micro switch assembly from the
push button and remove the cover.
3. Remove the 2 square drive screws that hold the
cardboard fan shroud in place.
4. Remove the wires that attach to the solenoid.
5. Remove the 4 screws that hold the assembly
into the cabinet. NOTE: IF THERE ARE SPAC-
ERS TO ADJUST THE SOLENOID ANGLE BE-
TWEEN THE PUNCHER BRACKET AND CABI-
NET, BE SURE TO USE THEM IN THE SAME
PLACE WHEN REASSEMBLING THE GAME.
