To ensure that all 12V electronic devices work without external power, the camping battery voltage should never fall below 12V (50%).
The lighting in the Camper Castle (Bürstner Limited T) only works when the camping battery is sufficiently charged or when the camper is connected to an external power supply.
To switch on the lighting, you must first switch on the power circuit via the on-board computer, which is located on the left-hand side of the vehicle when you get in.
The silver light switches for the interior are located to the right of the door, under the cupboards or inside the shelves. The small silver lights have their own light switch, which is a small black button next to the light itself:
There are numerous power sockets and USB ports throughout the vehicle:
- 230V sockets are next to the door in the compartments.
- USB and 12V sockets are located in the sleeping area and next to the door (USB type-B).
Please note the following:
- When stationary, do not charge any device in the driver's cab via USB. The starter battery will discharge and the engine may not start!
- 230V sockets: only work with an external power connection
- USB ports and 12V sockets: work without an external power connection, with a charged camping battery (always keep it above 50% or 12V).
- With a full battery, you can be self-sufficient for 1-2 days without a power connection, depending on usage. Then you need to drive for a while to recharge the battery or connect your camper to an external power source.
- 🚗 Slow driving & short distances → hardly any battery charge
- 🛣️ Long drives on motorways → better charge, but takes several hours
- 🔋 The starter battery is charged first, then the camping battery.
- ⚠️ Driving alone is often not enough to fully charge the camping battery.
- 🔌 Recommendation: charge externally every 48 hours to avoid energy shortages (especially at night 💤).
- Don't forget to unplug the power cable before driving off! For some models, you need to press the blue lever next to the plug downwards.
Troubleshooting
If the electricity or lights do not work, you can test several things:
- Check the charge level of the camping battery on the on-board unit.
- Check whether the power circuit on the on-board unit is switched on.
- Check whether the "Batterie-Trenn-Schalter" is pointing upwards in the direction of "EIN=ON". You will find this on the electrical block under the driver's seat:
- Check the large, red main fuse (50A) under the passenger seat:
Before any fuse is pulled, following safety measures is required:
- Turn off the engine and remove the key from the contact.
- Unplug the car from any external power supply.
- Pull carefully on the fuse by pulling from the sides.
- A damaged fuse can be burnt or have the connector broken (see picture). If so, please replace it. You can find them at petrol stations and hardware stores.
-
With an external power source: Check in the cupboard next to the toilet whether the RCD switches in the wardrobe (between the kitchen and bathroom on the driver's side) are pointing upwards:
- Check whether the cable or the camping socket is defective. Your friendly camping neighbour will probably help you out with a working cable and socket. 🥰
