Camper & Motorhome Electrical Repairs

Modern campers and motorhomes rely heavily on their electrical systems for comfort, safety, and convenience, which means even a small fault can quickly disrupt your trip. As an experienced caravan and motorhome service engineer, I provide comprehensive electrical repair services covering both 12-volt (leisure) and 230-volt mains systems. Whether you’re dealing with an intermittent power issue, a complete electrical failure, or planning preventative maintenance, I diagnose problems methodically and carry out repairs to industry standards, ensuring your vehicle is safe, reliable, and ready for the road.

Electrical issues in motorhomes are often more complex than in standard vehicles due to the interaction between multiple power sources. These can include the leisure battery, starter battery, mains hook-up, solar panels, split-charge relays, battery-to-battery chargers, and inverters. When one component fails or wiring deteriorates, the fault can cascade through the system. My approach focuses on identifying the root cause rather than masking symptoms, using proper testing equipment to check voltages, loads, continuity, and earthing.

One of the most common jobs I attend is battery-related faults. This includes leisure batteries not charging, draining too quickly, or failing altogether. Often the issue lies not with the battery itself, but with faulty chargers, worn split-charge relays, corroded terminals, or incorrect wiring. I assess battery condition, charging sources, and usage patterns, advising on repair, replacement, or upgrades where appropriate.

Another frequent problem involves mains hook-up and 230-volt systems. Tripping RCDs or MCBs, dead sockets, or appliances failing to run on mains power can all indicate underlying issues such as moisture ingress, damaged cables, or failed consumer unit components. Safety is critical with 230-volt electrics, so all repairs are carried out with careful inspection and testing to ensure compliance and peace of mind.

Lighting and accessory faults are also common, particularly in older campers. Flickering lights, blown fuses, non-working water pumps, heaters, fridges, or control panels are often traced back to poor connections, aged wiring, or overloaded circuits. These faults can be frustrating and difficult to pinpoint without experience, but systematic fault-finding usually reveals a straightforward repair.

I also regularly deal with solar panel and inverter issues, such as panels not charging batteries, incorrect regulator settings, or inverters cutting out under load. As these systems are increasingly popular, ensuring they are correctly installed and integrated into the existing electrical setup is essential for efficiency and battery longevity.

• Leisure battery not charging or losing power quickly
   
• No power from mains hook-up
   
• RCD or circuit breakers tripping repeatedly
   
• Blown fuses or recurring electrical faults
   
• Lights flickering or not working
   
• Control panels showing incorrect readings
   
• Water pump, heater, or fridge electrical failures
   
• Solar panels not charging the battery
   
• Inverter cutting out or not supplying power
   
• Corroded wiring, loose connections, or poor earthing
   

Regular electrical checks can prevent many of these issues before they become major problems. Whether you need a one-off repair, fault diagnosis, or advice on improving your electrical setup, I offer a professional, practical service tailored specifically to campers and motorhomes—keeping you powered up and enjoying your travels without unwanted interruptions.
