My BWM car's electrical system is acting up, and I have no idea where to start troubleshooting. What steps should I follow?
ReplyFirst, check the battery and make sure it's fully charged. Then, check the fuses and relays to ensure they are not blown. If those are fine, then it could be an issue with the alternator or starter. It's always best to consult a professional mechanic for further diagnosis.
Before checking any electrical components, make sure to disconnect the negative battery cable to avoid any electrical shocks. Then, using a multimeter, test the battery voltage, and if it's below 12V, it could indicate a failing battery. Other possible causes could be a faulty ignition switch or a wiring issue. Consider seeking help from a trusted mechanic for a proper diagnosis.
One common issue with BWM's electrical system is a faulty central locking system, which can drain the battery. If you notice any issues with the doors locking or unlocking, it's best to have it checked out by a mechanic. Also, regularly check the battery terminals for any corrosion and clean them if necessary.
