Lunar Caravan Electrical Problems

Caravanning is an enjoyable experience, but like everything, sometimes things can go wrong. One of the common issues faced by Lunar Caravan owners, especially the older models, is related to its electrical system. This article sheds light on these problems and provides potential solutions.

1. Problem: Inconsistent electrical operation.

  • Description: Some caravan users report that neither the 240v nor 12v systems work correctly. They find that only the fridge extractor fan and a few lights operate.
  • Possible Solutions:
    1. Ensure that your fridge is set to the correct power mode. The fridge typically works on gas or mains when pitched, and the 12v is controlled by a relay which runs the fridge while towing.
    2. For the lights, ensure that they are 12v, as these might be the only ones that work if the caravan is running on 12v.

2. Problem: Water pump, heater, and lights don’t work on mains.

  • Description: Users note that certain amenities like the water heater, fire, and lights don’t function when connected to mains.
  • Possible Solutions:
    1. Check the type of heater. For example, a ‘Carver cascade’ with a ‘G’ label indicates it’s gas-only. If it’s marked ‘GE’, it’s both gas and electric. This will help determine if your heater is meant to function with mains.
    2. Ensure the caravan 12v battery is charged and functioning. If the 12v system works when not connected to mains but doesn’t work when connected, the charger could be at fault.
    3. Ensure the switch connecting to the caravan’s power source is set to the caravan when not towing and to the car while towing.

3. Problem: Heater issues.

  • Description: Even when the ECM is set to caravan mode and auxiliary power is on, the heater doesn’t function properly. Though it might make a noise and even show a light indicator, it doesn’t produce heat.
  • Possible Solutions:
    1. Ensure all settings are correctly configured.
    2. Inspect all fuses with a multimeter. Sometimes, fuses might appear intact but are actually blown.

4. Problem: Power cut affecting certain appliances.

  • Description: After a power outage, some appliances like the fridge, lights, water pump, radio, and cooker ignition do not resume function, even though other devices like microwaves and sockets might.
  • Possible Solutions:
    1. A complete check of the fuses is necessary, as they may need replacement.
    2. Resetting certain devices or turning them off and on might also help.

5. Problem: Only a few appliances function.

  • Description: Some users, especially those with the 2006 Lunar Clubman model, find that only certain devices, like the microwave and heater, work without their blowers.
  • Possible Solutions:
    1. This is indicative of a larger electrical issue and may require professional intervention.

Conclusion:

While some of these problems might be fixed through simple troubleshooting, others may require expert intervention. Always remember to check the basics first, like fuses and switch positions, before diving deeper into the problem. If you’re unsure, it’s always recommended to consult with a professional to ensure your caravan’s electrical system remains safe and efficient.
