Why does my radio stays on but no power in my 2000 Mercedes s430?

If your 2000 Mercedes S430 radio stays on but there is no power to the vehicle, it could be due to a few reasons. A common issue could be a faulty ignition switch or a problem with the battery, such as a weak connection or low charge. Additionally, check for blown fuses that might affect electrical systems. If the battery is fully charged and connections are secure, it may be necessary to have the ignition system or wiring inspected by a professional.
