Auto Electrics
Electrical faults come and go, which is why parts swapping rarely works. We trace them with wiring diagrams, meters and diagnostic equipment.
Why book with us
Auto Electrics with clear advice.
Modern cars have dozens of control modules talking to each other over a network of wires. A corroded plug, a chafed loom or a failing earth can cause anything from a dead electric window to a dash full of warning lights. We start with a full scan, then test the circuit itself rather than guessing at parts.
Intermittent faults take patience. If it only happens when it rains or on bumpy roads, tell us when you book and we will plan the testing around it so we can catch the fault in the act.
Circuit testing
Wiring diagrams, meters and live data used to pin down the faulty part of the circuit.
Intermittent faults
We recreate the conditions that trigger the fault rather than hope it shows.
Repair, not just replace
Wiring, plugs and earths repaired where that is the proper fix.

Common questions
- Why does my battery keep going flat overnight?
- Something is drawing power with the car switched off, such as a module that will not go to sleep, a boot light or an aftermarket accessory. We measure the drain and pull fuses one at a time to find the circuit, then trace it to the part at fault.
- Can you fix electric windows and central locking?
- Yes. The usual causes are a failed window regulator or motor, a broken wire in the door hinge or a faulty door lock actuator. We test which it is so you are not paying for parts you do not need, on everything from Vauxhall Astras to Mercedes C-Class.
- How long does electrical fault finding take?
- Simple faults are often found within the first hour. Intermittent faults can take longer, and we will agree a time limit with you before we start so costs never run away. Call 01384 936310 to talk it through.
