The game has a passive infrared sensor (PIR sensor) located in the top of the canopy to detect people trying to climb in the game to cheat. When the sensor senses a change in an object’s temperature (a person), the game will display “TILT” on your score display. There are two ways the game will behave when this condition occurs depending on what you have set option 19 to. A setting of 0 will end the current game and allow the player to reinsert money to play again. A setting of 1 will lock the game in 7L17 mode until the operator cycles power to the game.
Here are some steps to troubleshoot this issue:
1) using a jumper wire with the power off short pins 2 and 3 of the J26 connector together, turn the game on and coin up.
a) if you are able to play the game then the fault is likely the cheat sensor (Replacement part number BL1332X) or an open in the harnessing that connects the cheat sensor to the main board.
b) if you are not able to coin up the game then the fault is the main board and you will need to send the board in for repair and return or advance replacement.
The pin out for connector J26 are:
a. Pin 1 is 12-volt DC positive power.
b. Pin 2 is the cheat signal. 0 volts DC not activated, 5 volts DC activated.
c. Pin 3 DC ground.
