Fault Finding & Wiring Repairs
Structured electrical fault finding for damaged wiring, poor connections, shorts, open circuits, voltage drops and intermittent harness problems.
Practical help for fault finding & wiring repairs
Structured electrical fault finding for damaged wiring, poor connections, shorts, open circuits, voltage drops and intermittent harness problems.
Tell us your vehicle make and model and what you need help with. We will review the request, confirm the practical scope and discuss the next step before work is agreed.
When to get in touch
- A fuse that repeatedly blows after replacement
- A component that works only when the vehicle or wiring is moved
- Intermittent loss of power to lights, windows, sensors or accessories
- Evidence of damaged, rubbed, corroded or previously repaired wiring
- Electrical faults that appear after water ingress, body repair or accessory installation
- A diagnostic code indicating circuit high, circuit low, open circuit or short to ground/power
What we may check
- Relevant fuse and relay feeds before deeper circuit testing
- Power and ground integrity at the affected component where access allows
- Connector condition, terminal tension and visible corrosion or heat damage
- Continuity or voltage-drop testing of suspect sections rather than relying only on visual inspection
- Harness routing near moving, hot or sharp areas where chafing can develop
- Existing aftermarket wiring or previous repairs that may influence the circuit
Possible next steps
- Repair of an accessible damaged wire or connection when suitable
- Identification of a harness section that requires more extensive repair or replacement
- Correction of poor earth or supply integrity
- Isolation of an aftermarket accessory or previous modification that is contributing to the fault
- A clearer boundary for further dismantling if the affected section is not readily accessible
Before your visit
- Describe exactly which feature fails and whether other features fail at the same time
- Tell us if the fault changes when doors, boot, steering or seats are moved
- Mention any water leaks, bodywork or accessory installations around the time the problem started
- Do not keep installing larger fuses; use only the specified fuse rating
- Provide photos of any visible damaged wiring if available
Tell us which function fails, whether the fault is intermittent and if there has been water ingress or recent bodywork. We can discuss access and testing before proposing a wiring repair.
Send us the details of your vehicle.
Include the registration, a short description and a photo of the issue if it helps. An online request is reviewed by the workshop before an appointment is confirmed.
