On-site diagnostics & repair of a squirrel racing game for a local play centre. Issues manifested as multiple motors no longer working.
- Mechanical issues identified on one track leading to a stalled motor burning out components
- Multiple burned out motor relays replaced
- Addition of a fuse on motor power supply
- Motor speed controller repair:
- Burned trace repaired
- Shorted MOSFET identified
- All MOSFETs replaced with a lower Rds equivalent to support more power
- Original flyback diodes identified as the wrong type for this application. Replaced with a Schottky diode
- Addition of a capacitor and MOV across each motor to lessen arcing, and therefore premature damage to the relays.
