How to Fix / Troubleshooting
Safety: Turn OFF the mower and disconnect the battery before inspecting internal wiring.
- Check battery connection: Open the battery compartment and ensure the TerraMow battery connector is fully seated and not moving when gently tugged.
- Inspect power switch: Operate the main power switch several times and feel for any looseness or intermittent contact.
- Wiggle test (advanced): With the mower ON and safely supported (blades disabled), gently wiggle the wiring harness near the main board to see if power cuts out, indicating a bad connection.
- Repair or replace: Repair any loose connectors and replace the TerraMow main power switch or main control board if internal faults are found.
