Possible Causes
Failing low-voltage PSU on PCB, Overheating of main processor, Firmware bug, Short on low-voltage accessory wiring
How to Fix / Troubleshooting
Safety first: Frequent reboots can interrupt charging unexpectedly; monitor vehicle state.
- 1. Check ventilation: Ensure the Zappi is not covered and has adequate airflow around it.
- 2. Firmware update: Update to the latest firmware to address any known stability issues.
- 3. Disconnect accessories: Remove any third-party devices powered from the Zappi’s low-voltage outputs to reduce load.
- 4. Inspect PCB: With power off, look for signs of overheating or damaged components on the main PCB.
- 5. Temperature monitoring: If possible, use the menu or app to monitor internal temperature and see if reboots correlate with high temps.
- 6. Replace main PCB if unresolved: Persistent random reboots usually indicate a failing PSU or processor on the PCB.
