Electrical Fault Diagnostics & Rectification
When 3 Garages Say "No Fault Found" - We'll Find It
Electrical gremlins don't follow simple patterns. They hide in wiring looms, appear randomly, drain batteries overnight, then vanish when you need to show someone. We hunt them down systematically.
Is This Service Right For You?
Warning lights that come and go without pattern
Battery draining overnight despite new battery installation
Multiple garages visited with no permanent solution
Electrical systems working intermittently or not at all
Been told "it needs a new module" without clear explanation why
Why Electrical Faults Defeat Most Garages
Modern cars contain miles of wiring, dozens of control modules, and 100s of sensors all communicating constantly. When something goes wrong, generic code readers are borderline useless.
Finding the real fault requires proper test equipment, systematic approaches, and patience. While others throw parts at problems hoping something sticks, we trace every circuit, test every connection, and isolate the actual failure point.
That broken wire hiding in a loom? That corroded ground connection behind a panel? That failing module sending bad data? We find them.
Complete Electrical Diagnostic Service
Comprehensive system scanning - Every module interrogated, all fault codes documented
Live data analysis - Monitor system behavior during fault conditions
CANbus communication testing - Verify data exchange between modules
Wiring continuity checks - Test circuits from end to end
Voltage drop testing - Find high resistance connections causing issues
Current draw analysis - Identify parasitic drains killing batteries
Component isolation testing - Prove which part actually failed
Our Deep Diagnostic Process
Gather The Full History:
Understanding when faults occur, what's been tried, and what temporarily worked provides clues.
Systematic Testing:
Following manufacturer test procedures, not random checking. Document findings at each stage.
Isolate The Root Cause:
Using specialist equipment, and specific analysis techniques, we pinpoint exactly where things have gone wrong.
Provide A Clear Explanation:
Show you what we found. Explain why it failed. Present repair options honestly.
Permanent Rectification:
Fix the actual problem properly. Retest all related systems before signing it as done.

If a deeper diagnostic is required, you will be contacted.
Because of the way deeper diagnostics can be, we can't estimate how long a deep dive diagnostic will be,
however our team will keep in touch with you every step of the way.

Faults We've Solved
"Was at my wit's end with my 2014 2.2 diesel Mazda 3 after developing multiple engine fault warning lights... Jay and his team traced the fault, had it repaired and it now runs like a dream... A very friendly, knowledgeable team who gave good advice..." - Alan Davies
You're my 3rd garage. How could you find it?
We use completely different methods of finding. Oscilloscopes show what scanners miss. Patience and perspective beats "the parts cannon". We're so prolific in what we do, we're used by other Garages and Dealers to find faults.
Will you start replacing modules?
Only if we can prove it’s failed. We repair where possible, many "failed" modules just need diagnosing properly (as the problem can be elsewhere).
How do I know it's properly fixed?
We replicate fault conditions after repair to prove it's solved.
Can you fix wiring looms?
Yes. We repair factory looms properly under the correct specifications however if the damage is significant, the loom cannot be repaired and will have to be replaced.
End The Electrical Mystery
Stop throwing money away. Whether it's parasitic drains, intermittent failures, or persistent warning lights, our proper diagnostics and fixes find answers.
