Auto electrics in Oslo
Oslo Bilelektriske has specialist expertise in systematic fault-finding and repair of electrical faults. We find the cause behind cable breaks, short circuits, earthing and contact faults, parasitic battery drain and intermittent faults – for all car makes.
Electrical faults we find and repair
- Cable breaks, earthing faults, contact faults, corrosion and damage in wiring harnesses.
- Parasitic battery drain testing when the battery keeps discharging or the car is left with a flat battery.
- Short circuits, blown fuses and components drawing abnormal amounts of current.
- Intermittent and periodic electrical faults that come and go, and therefore require measurement and systematic diagnostics.
- Faults in starting, charging, lighting, comfort and control systems.
- Diagnostics of control units (ECU), communication and electrical signals.
Why does the car battery go flat overnight?
If the car loses power while parked, we need to investigate more than whether it starts after charging. Battery condition, charging and current draw while the car is parked may be relevant parts of the investigation. At Oppsal Bilservice | Oslo Bilelektriske in Ensjø, we agree what should be checked on your specific car.
The battery goes flat after a short time, even though I have charged it.
Tell us how long the car stands before the problem returns: overnight, over a weekend or after several days. State whether the car mainly makes short trips and whether you recently charged or replaced the battery. This helps us plan the investigation.
Why does my new car battery go flat?
A new battery does not establish whether charging works or something draws current while the car is parked. We investigate the cause before recommending action. A parasitic drain test measures current draw while the car is parked and may be relevant when the battery repeatedly goes flat.
What should I include when requesting fault-finding?
Include the registration number, when the problem began, how long the car had stood and what has already been tried. Copy any dashboard warnings. You do not need to know which part is faulty. Mention recently fitted equipment or other work on the car.
For electric and hybrid cars, we need to distinguish the low-voltage system from the traction battery. State the model and warning text so we can agree which system the request concerns. Will the car not start, even though the lights work? Read more about starting problems.
Describe the problem in the form. An employee confirms the appointment and agrees the price.
Fitting of accessories
We fit and wire electrical accessories professionally. Before fitting, we check the car's electrical system, power requirements, fusing, cable sizing and placement, so that the solution is reliable and integrated without unnecessary fault messages.
Frequently asked questions about auto electrics
Why does the car battery keep going flat?
Possible causes include a weak battery, a charging-system fault or a component drawing current while the car is parked. We can test the battery and charging system and perform a parasitic-drain test to identify the cause.
Can you find electrical faults that come and go?
Yes. Intermittent faults may require systematic measurements, inspection of wiring and connectors and analysis of stored fault codes. Please tell us when and under which conditions the fault occurs.
Do you fit electrical accessories?
Yes. Before fitting, we check factors including power requirements, fusing, cable sizing and placement so that the equipment is connected professionally.
