Caravan Electrician Gladstone & Calliope
Caravan battery not charging, lights failing, trailer plug damaged or electric brakes playing up? Total Mobile Mechanical Services provides caravan electrical repairs across Gladstone and Calliope, with qualified auto-electrical capability for caravans, camper trailers, motorhomes and tow vehicles.
A caravan electrical fault can involve the caravan, its batteries, the tow vehicle or the connection between them. Replacing a battery, fuse or plug without testing the whole circuit may hide the real cause and leave the problem ready to return on the next trip.
Our qualified auto electrician uses a diagnostic-first approach. Battery condition, charging voltage, current flow, voltage drop, earth paths, connectors, wiring condition and system operation can be checked before major parts are recommended.
Because our team also works across mechanical and vehicle-diagnostic systems, connected problems can be assessed together. That is useful when an apparent caravan wiring fault is actually affected by tow-vehicle charging, brake-controller setup, battery condition or a mechanical problem at the coupling or running gear.
Mobile support is available for suitable jobs, backed by multiple workshop facilities and a larger fully equipped workshop when repairs need more time, access or equipment than an on-site visit allows.

Caravan Electrical Repairs in Gladstone and Calliope
Our caravan electrical repair service focuses on the low-voltage systems that keep a caravan safe, connected and usable while travelling or camping.
- 12V battery, cable, terminal and earth testing
- Caravan battery charging and battery-drain diagnosis
- Anderson plugs, tow-vehicle feeds and auxiliary charging circuits
- Trailer plugs, sockets, road lights and damaged wiring
- Electric brake, brake-controller and breakaway-system wiring
- Fuses, relays, connectors, switches and suitable harness repairs
- Intermittent faults, repeated fuse failures and poor previous repairs
- Solar-input and DC-DC charging fault diagnosis
- Low-voltage accessory and power-supply fault finding
- Mobile caravan electrician support for suitable local jobs
When the concern sits outside the caravan itself, our starting, charging and wiring repair service can continue the diagnosis through the tow vehicle. Broader electronic faults can also draw on our advanced vehicle diagnostic capability.
Caravan Battery and Charging Fault Diagnosis
A caravan battery that keeps going flat is not automatically a failed battery. The cause may be poor battery condition, low charging voltage, excessive resistance in a cable or earth, a faulty connection, an unsuitable charging path, a DC-DC charger problem or an electrical load that remains active when it should be off.
Testing can include battery condition, resting voltage, charging voltage, current flow, voltage drop, terminal and earth condition, fuse protection, cable sizing and charger operation. The aim is to identify why the system is not charging or holding charge before parts are replaced.
This is particularly important when the caravan charges correctly from one source but not another. Mains chargers, tow-vehicle feeds, solar inputs and DC-DC systems each have different operating conditions, so the fault needs to be reproduced and tested in the circuit that is actually failing.
Trailer Plugs, Road Lights and Caravan Wiring Repairs
Caravan wiring lives in a difficult environment. Movement, vibration, water, dust, corrosion, heat, tight bends and repeated coupling can damage cables and terminals. A poor earth or corroded plug can affect several lights at once, while a short circuit may only appear when the van moves or a particular circuit is loaded.
We can test trailer sockets and plugs, road-light circuits, fuse and relay feeds, accessible harness sections, connectors and earth paths. Suitable wiring repairs are completed with correct protection and connections rather than twisting wires together or fitting a larger fuse to hide the problem.
If the van also has coupling, suspension, bearing, brake or running-gear concerns, the job can continue through our caravan mechanical repair service.
Electric Brakes, Brake Controllers and Breakaway Wiring
Reliable electric brakes depend on more than the brake assemblies. The tow-vehicle controller, trailer plug, power feed, earth path, wiring condition, breakaway battery and caravan brake circuits must work together.
Symptoms can include weak or uneven braking, brakes applying intermittently, a controller showing no trailer connection, warning messages, excessive brake action or a breakaway system that does not operate correctly.
Electrical testing can separate controller or wiring problems from mechanical brake adjustment and component wear. That gives the repair a clear direction and helps avoid replacing electrical parts when the actual concern is mechanical, or vice versa.
Intermittent Caravan Electrical Faults and Advanced Testing
Intermittent faults are often the most frustrating because the caravan may work perfectly in the driveway and fail only after vibration, rain, heat or a long drive. These problems need a logical test process, not a catalogue of guessed parts.
Diagnosis may include visual inspection, circuit continuity, loaded voltage-drop testing, current measurement, connector movement testing and checking how the fault changes under real operating conditions. Previous accessory installations and old repairs are also considered because poor joins, unprotected cables or overloaded circuits can create problems long after the original work was completed.
Where possible, bring the caravan and tow vehicle together. Testing the complete setup gives the best chance of reproducing charging, lighting and brake-controller faults accurately.
Mobile Caravan Electrician Support Backed by Workshops
Mobile diagnosis is backed by workshop facilities for repairs that need more equipment, access or time.
Our fully equipped mobile workshop can support suitable caravan electrical diagnosis and repairs around Gladstone, Calliope and nearby areas. That can be valuable when a caravan is difficult to move, a towing fault needs to be tested with the complete combination or the issue has left the van unusable.
Mobile service does not mean every job should be completed on site. Some repairs require controlled workshop conditions, extended testing, lifting equipment, parts availability or access that is not practical at a driveway or campground.
Total Mobile Mechanical Services has multiple workshop facilities, including the capacity to handle larger and more involved repairs properly. Customers receive a practical pathway from mobile assessment to workshop repair instead of being left with the limitations of a single service vehicle.

Caravan Solar, Lithium and 12V Upgrade Work
This page is focused on fault diagnosis and electrical repairs. If the goal is to add solar capacity, convert to lithium, install a DC-DC charger or redesign an off-grid 12V system, our dedicated caravan solar, lithium and 12V upgrade service is the correct starting point.
Keeping the services separate means a repair enquiry is not pushed into an unnecessary upgrade, while an upgrade can be planned around battery chemistry, expected loads, charging sources, cable protection and how the caravan will actually be used.
Low-Voltage Auto Electrical and 240V Work
Our auto-electrical service covers caravan and tow-vehicle low-voltage systems such as batteries, charging circuits, lights, brakes, plugs, sockets, wiring and suitable 12V accessories.
Fixed 240V wiring, switchboards, mains outlets and other regulated electrical work must be completed by an appropriately licensed electrical contractor where required. We will explain the boundary clearly so the correct trade handles each part of the job.
