How to Fix / Troubleshooting
Safety first: Turn OFF the generator and disconnect battery negative before opening the control panel.
- Check fuses: Locate and test the low-voltage fuse feeding the display. Replace if blown and investigate cause.
- Inspect connectors: Ensure the display module power and data connectors are fully seated.
