AL-KO ESC No Light Troubleshooting

Question:

The LED lights on my AL-KO ESC for my caravan, used to start up and stay on green. Now, when fully connected I’m getting no LED lights at all, can you help?

Hey Peter!

We don't carry this product but when I looked it up online I was able to find the manual and if the light isn't showing green or red that means the ESC isn't getting power so you need to follow these steps:

No power to the ESC:

Check that the 12 pin connector is plugged in to the tow vehicle.
- Reconnect the 12 pin connector.

Check that ESC connector is plugged into the ESC under the caravan.
- Reconnect the ESC connector.

No power supplied from tow vehicle.
- Check for 12 volts at the 12 pin connector & check fuse (If fitted).
- Repair any damaged cables.
- Clean the 12 pin connector.
- Replace fuse if required.
- Replace cables and/or connector if required.

No power at ESC connector. Check for 12 volts at ESC connector.
- Clean the connector.
- Repair any damaged caravan cables or replace if necessary

Check that the cables are not damaged.
- Repair or replace the cables if necessary.
