Electrical fault finding
Methodical investigation of wiring, sensors, relays and control circuits. Trace the fault, explain the cause and agree the repair.
Electrical fault finding. Controls expertise.
Practical solutions when your equipment needs attention.

From a faulty relay to a control system that needs a rethink, a practical approach to understanding the problem and deciding what comes next.
Methodical investigation of wiring, sensors, relays and control circuits. Trace the fault, explain the cause and agree the repair.
Investigate machine sequences, interlocks and alarms. Improve diagnostics and make existing systems easier to understand and maintain.
Support with inverter and servo faults, parameters, commissioning and communication between drives and the wider control system.
Small modifications, planned upgrades and options for ageing controls. Start with what the machine needs and build a sensible scope around it.
Work is assessed individually for suitability, access requirements and availability.

I’m Thomas Thurston, a control systems engineer with experience in special purpose machinery and automotive production equipment.
I enjoy getting to the bottom of problems: tracing the circuit, understanding the sequence and working out why a machine isn’t doing what it should.
Speak directly with the engineer doing the work. Clear findings, an agreed scope and practical advice on the next step.
Useful information up front makes it easier to assess the job and plan the right support.
Share the equipment details, symptoms, alarms and location. Photos of the control equipment can help establish the starting point.
Confirm whether the job is a fit, what access or information is needed, and a suitable time to investigate.
Get clear findings and a practical recommendation, whether that means a repair, further investigation or a planned change.
Tell me about the equipment and the problem. Include the location and when you need support, and I’ll get back to you to discuss whether I can help.
Based in Staffordshire, with work in the West Midlands considered by arrangement. Include your site location in the enquiry.
The machine type, controller or drive model, the symptoms, any alarm messages, and your site location. Mention recent changes and whether electrical drawings or program backups are available.
Often the first step is to identify the hardware and understand the fault. Repairs and upgrade options depend on the equipment, available information and parts.
