What to send before an electrical diagnosis
When booking, include the registration, postcode, warning messages and the exact equipment that is not working. Explain whether the fault is permanent or intermittent, when it started and what was repaired or fitted beforehand. Photographs or a short video can help identify the affected circuit before the visit.
If the battery goes flat, say how long the vehicle can stand before it fails to start, whether the battery has been replaced or tested and whether any tracker, dash cam, radio, alarm or other accessory is connected. For charging faults, mention battery or charging warnings, slow cranking and any recent alternator or belt work. Do not repeatedly replace fuses that blow; that can hide a short circuit or cause further damage.
Electrical diagnosis may involve battery and charging tests, fuse and voltage-drop checks, wiring measurements, scan-tool communication and checking whether a module is being kept awake. An initial visit may identify the fault or produce the next repair step; parts and access requirements vary by vehicle.
Use the booking form above to send the vehicle and fault details. Arrange a safe place to work and provide keys needed to reproduce the problem.
