Electrical faults are among the most difficult vehicle problems to diagnose correctly. RHR Automotive's team uses professional auto-electrical diagnostic equipment to trace faults accurately and efficiently — covering everything from battery and alternator testing to complex wiring issues and ECU problems.
A modern vehicle contains kilometres of wiring, dozens of electronic control units, and hundreds of sensors working in coordination. When an electrical fault occurs, it can manifest in many ways — a warning light, an intermittent failure, a parasitic drain on the battery, or a component that simply stops working without any obvious cause.
Auto-electrical work demands a methodical approach. At RHR Automotive, we combine professional scan tools with multimeters, oscilloscopes and wiring diagrams to trace faults systematically — rather than replacing components on a best-guess basis. This saves time and money and ensures the underlying fault is actually resolved.
We handle a broad range of auto-electrical work, from relatively straightforward battery and alternator replacements to more complex tasks such as diagnosing parasitic battery drains, tracing short circuits, testing ECU inputs and outputs, and repairing damaged wiring harnesses.
Electrical faults left undiagnosed can strand you without warning, drain your battery, damage sensitive ECUs, or cause intermittent failures that make your vehicle unreliable. Professional auto-electrical diagnosis resolves the problem at source rather than masking symptoms.
Based in Poole, serving Bournemouth and the wider Dorset area. You deal directly with the mechanics working on your vehicle — no call centres, no middlemen.
We invest in professional-grade diagnostic tools to identify faults accurately, saving you time and unnecessary repair costs.
We'll explain exactly what needs doing and why before any work begins. No surprise invoices.
From city cars to light commercials, our workshop handles a wide range of vehicles from leading manufacturers.
Vehicle batteries have a typical lifespan of 3 to 5 years. We test battery health under load and replace when necessary.
A failing alternator cannot recharge the battery effectively, leading to progressive electrical failure during a journey.
Intermittent starting problems or a characteristic clicking noise on ignition often indicate a failing starter motor.
An unknown current draw discharging the battery overnight requires systematic circuit isolation to identify the source.
Rodent damage, corrosion and chafed insulation cause shorts and open circuits that can be extremely challenging to trace.
Crankshaft position sensors, cam sensors and ABS sensors all trigger fault codes and can cause significant drivability issues.
Based in Poole, we regularly work with customers from across the region.
