Car Electrics & Auto Electrical Fault Diagnosis
Modern vehicles rely on complex car electrics to control everything from starting and charging systems to lighting, engine management, immobilisers and comfort systems. When a warning light appears or an electrical fault develops, simply replacing parts rarely fixes the problem.
At Car Alarm & Radio Services, we specialise in car electrical diagnostics using professional dealer-level diagnostic equipment, wiring diagrams, oscilloscopes and electrical testing equipment to accurately identify the cause of the fault.
We regularly diagnose and repair:
Are You Experiencing Any of These Problems?
✓ A fuse keeps blowing
✓ An electrical switch has stopped working
✓ Broken or damaged wiring
✓ No communication with a control module
✓ Warning lights on the dashboard
✓ Battery drain
✓ Intermittent electrical faults
✓ Lights or accessories not working correctly
If so, we can help.
