A campervan or motorhome carries two electrical lives. The base vehicle starts, charges and drives like any other van, while the habitation side runs lights, water pump, heating controls and accessories from a separate leisure battery. That second system has its own wiring, fuses and failure patterns, and faults there can ruin a trip even though the vehicle itself drives perfectly well.
Our campervan and motorhome electrics service covers the living-area circuits and the link between the two systems. Leisure batteries are load-tested honestly, split-charge relays and modern DC-DC chargers are checked for correct operation, and 12V habitation wiring is traced when lights, pumps or control panels stop responding. The aim is measured answers: is the battery tired, is it simply never being recharged properly on the drive, or is something quietly draining it between trips?
Everything is mobile, because leisure vehicles often sit on storage sites or driveways rather than near workshops. Car Electrician Birmingham works across Birmingham and the West Midlands, open 24 hours, attending homes in Kings Heath or compounds near Northfield. Related vehicle-side needs connect naturally with car battery replacement for the starter battery and towbar and trailer electrics where a caravan shares the outfit.
What's included in campervan & motorhome electrics
Leisure battery testing and fitting
Capacity and load testing of the leisure battery, with correct replacement fitting where it has genuinely failed and terminal connections cleaned and secured properly.
Split-charge relay checks and repair
Voltage-sensitive and ignition-triggered split-charge relays tested to confirm the leisure battery actually receives charge while driving, with failed relays or wiring renewed.
DC-DC charger wiring checks
Battery-to-battery chargers inspected for correct wiring, settings and output, especially important on smart alternator vehicles where a simple relay no longer charges effectively.
12V habitation circuit fault finding
Dead habitation circuits traced through fuse boards, isolation switches, control panels and wiring runs until the break, short or failed component is identified and repaired.
Lighting and water pump circuits
Interior lighting failures and silent water pumps tested at the fitting, switch and feed, separating a failed pump or lamp unit from a wiring or fuse board problem.
Solar controller and caravan road lights
Solar charge controller wiring checked for correct battery and panel connections, plus caravan road-light circuits tested where a towing outfit forms part of the setup.
Why the leisure battery is flat even though you drove for hours
Driving should refill the leisure battery, so repeated flatness despite long journeys points at the charging link rather than the battery alone. A split-charge relay that no longer switches, a blown high-current fuse, corroded connections or broken cable along the chassis can leave the leisure side declining steadily with every trip away.
Smart alternators add a modern twist. Vehicles that vary charging voltage for economy can leave a traditional relay setup barely charging the leisure battery at all, which is where a DC-DC charger earns its place by drawing power deliberately and presenting it at the right voltage. Testing output at the leisure battery with the engine running settles which story applies to your van, instead of parts being guessed at in sequence.
Habitation faults: wiring, fuse board or the appliance itself?
When interior lights die together or the pump and panel fall silent at once, suspicion belongs with shared supplies: the habitation fuse board, the main isolation switch, a master fuse near the leisure battery, or the earth return. Single-item failures tell a narrower story, and testing voltage at the fitting itself quickly shows whether power arrives and the appliance has failed, or power never set off in its direction.
Intermittent habitation faults often trace to connections disturbed by road vibration, damp in rear corners, or previous conversion work of variable quality. Our battery drain fault finding methods also apply here when a leisure battery empties itself on a storage site: standing draw is measured, then circuits are isolated until whatever stays awake — a control panel, a fridge circuit, a forgotten accessory — reveals itself on the meter.
How campervan & motorhome electrics works
Explain the habitation problem
Call or WhatsApp on +44 7425 435697 with the vehicle, conversion type if known, and whether the fault affects charging, one circuit or everything.
Testing at home or storage
Leisure battery condition, charging input with the engine running, and standing draw are measured where the vehicle is kept, without needing hook-up.
Trace and agree the repair
The faulty relay, charger, fuse board section or wiring run is identified, and repair or replacement options are explained before work proceeds further.
Repair and demonstrate the system
After repair, charging is shown working, habitation circuits are switched on one by one, and lights and pump operation are confirmed with you present.

What is the difference between a leisure battery and a starter battery?
A starter battery delivers a short, heavy burst to crank an engine, while a leisure battery is built to supply modest power steadily for hours and tolerate deeper discharge. They are not interchangeable in practice. Fitting a starter battery for habitation use leads to short life, and each battery in the vehicle is tested against its own job.
Why is my leisure battery not charging while I drive?
Common causes include a failed split-charge relay, a blown fuse in the charging cable, corroded or broken wiring between the batteries, or a smart alternator that a basic relay setup cannot work with effectively. Measuring voltage at the leisure battery with the engine running shows immediately whether charge arrives, and the link is then traced to the failing point.
Do I need a split-charge relay or a DC-DC charger?
Older vehicles with conventional alternators usually charge well through a split-charge relay. Newer vehicles with smart alternators often need a DC-DC charger, which actively draws power and charges the leisure battery at a controlled voltage. Your vehicle type and measured charging behaviour decide the recommendation, rather than fashion or the most expensive option available.
My 12V lights and water pump have stopped working. What is likely?
When several habitation items fail together, look first at shared supplies: the main leisure fuse, isolation switch position, fuse board feeds or a lost earth for the living-area circuits. A single dead item points more towards its own switch, wiring or the unit itself. Testing at the fuse board and then at the fitting separates those possibilities quickly and accurately.
Can you check my solar panel and controller wiring?
Yes, solar controller wiring is checked for correct panel and battery connections, sound terminals and sensible charging behaviour in daylight. A controller wired in the wrong order, a failed in-line fuse or corroded external connections can silence an otherwise healthy panel. Panel output itself is also verified, so you know whether the fault is generation or wiring.
Can you work on my motorhome at a storage site?
Yes, storage sites are a normal workplace for this service, as are driveways and home parking spots. The vehicle simply needs safe access around it and permission arrangements for the site itself are left with you. Testing equipment is self-contained, so no mains hook-up is required for the electrical checks and repairs to be completed properly.
Can you also look at caravan road lights?
Yes, caravan road-light circuits are part of this work, from the car socket through the plug to the caravan lamps. Many outfits combine a motorhome or campervan with towing duties, and the same testing approach applies throughout. Faults are separated into vehicle side and caravan side before repairs begin, so effort goes to the half that owns the problem.
