On whack-a-mole and pop-up redemption games like Cat & Mice, players use physical hammers or soft padded bats to hit mice targets that pop up or rotate out of holes.
A frequent technical challenge for field technicians when servicing older or rare cabinets like Cat & Mice is encountering Error 1-1 (Err 1-1) without access to an official service manual or manufacturer schematic.

🔍 Failure Analysis Without a Manual (Memahami Cara Kerja Mesin)
When faced with no documentation, technicians must analyze system operation by comparing it to similar arcade platforms (such as Happy Frog, Happy Kangaroo, or traditional whack-a-mole machines).

Self-Test Initialization Sequence:
Like most arcade redemption games, Cat & Mice performs a mandatory Power-On Self-Test (POST) upon startup:
Display Check: Digital segment LEDs count down or flash briefly.
I/O & Drive Check: The CPU energizes the rotary target motor and actuates solenoids to verify home position sensors.
The Fault: During boot, the mainboard attempts to spin the rotary target motor. When the motor fails to move, the home position sensor never triggers, causing the CPU to time out and display Error 1-1.
🧠 Root Cause Analysis: Broken Internal Motor Cable

Primary Cause:
While technicians often suspect a burnt motor coil, blown driver MOSFET, or dead sensor, Error 1-1 on Cat & Mice is frequently caused by a broken internal conductor inside the motor's power input cable.
Internal Wire Fatigue: Due to constant mechanical vibration and flexing from the rotating target mechanism, the copper strands inside the wire insulation snap internally—often while the outer PVC insulation remains completely intact visually.

Detailed Repair Steps:
Understand Machine Components (Observasi Komponen):
Open the top playfield panel to access internal drive components: DC Rotary Motor, Pop-up Solenoids, Home Position Optoelectronic Sensors, and the Main Power Harness.
Perform Continuity Test with a Multimeter:
Unplug the 2-pin motor power harness from the mainboard/I/O board.
Set your multimeter to Continuity Test Mode / Resistance ($\Omega$).
Measure from the board connector terminal pin down to the motor solder pad.
Flex and gently pull the wire while testing: If the multimeter beeps intermittently or shows Open Circuit ($\infty\,\Omega$), the inner copper core is fractured inside the wire sleeve.
Repair or Replace the Motor Input Harness:
Cut out the fatigue-damaged section of the wiring harness.
Strip the wire ends and solder high-flexibility stranded copper wire (18–20 AWG).
Seal all soldered joints using heat-shrink tubing to ensure insulation and mechanical strain relief.
Test Motor Bench Performance:
Apply external $+12\text{V}$ or $+24\text{V}$ DC power directly to the motor terminals to confirm the motor spins freely without mechanical binding.
Re-assemble and Verify Self-Test:
Reconnect the harness to the mainboard and power on the cabinet.
Observe the boot cycle: the rotary motor will execute its homing rotation, the position sensor will register, and Error 1-1 will clear automatically.
