Critical
The ABB charger performs an insulation resistance test before starting DC charging. This test failed, meaning there may be moisture or damage in the cable or connector.
What to do
- Check the connector pins for moisture, dirt, or visible damage
- Dry the connector if it appears wet and try again
- Try the other connector on the same charger if available
- If the test keeps failing, move to a different charger and report the issue
Who's responsible?
- This is likely a charger hardware issue
