How to Fix / Troubleshooting
Safety: You are dealing with live mains. Turn OFF the breaker and verify with a meter before touching any wiring. If you are not qualified, call an electrician.
- 1. Check the breaker:
- Verify the dedicated breaker feeding the AMPROAD charger is ON and not tripped.
- Reset if necessary and see if the charger powers up.
- 2. Verify supply voltage:
- Have a qualified person measure voltage at the charger input terminals to confirm correct voltage is present.
- 3. Inspect terminal block:
- With power OFF, open the charger and check that all input wires are securely clamped in the terminal block.
- Tighten any loose connections.
- 4. Check internal fuse:
- Locate any internal fuses on the AMPROAD power board.
- If a fuse is blown, investigate for short circuits before replacing with the exact same type and rating.
- 5. Auxiliary PSU check:
- If input power is present but the display remains off, the auxiliary power supply on the power board may have failed.
- Replace the AMPROAD power board or auxiliary PSU module.
