E320 Weird Electrical Problems
Hello All,
My E320 4 Matic have a weird electrical problem since I bought it. When I bought the aux battery was bad (there was an error message on the dashboard) so I change it with Die Hard Platinium.
Everything was nice but I notice some fluctining on headlight bulbs and inside lights. For example, the lights are open and I try to push the window button to close windows which already closed, the fluctining happening. Also, the vibration from the engine can feel easily. There is no warning light or error message. I try to take both lights on video. Any thoughts about it? Thanks!

You will be rewarded for your attention to this detail. Low voltage is a silent killer that causes damage to your whole electrical system with starter at the top of the list due to super high currents
Fluctuating lights:
You need to figure what is causing these voltage fluctuations.
My short list being...:
- a bad/old voltage regulator?
- a bad prefuse cable connection?
- a fuse box SAM issue?
Use a DVM to poke around the Prefuse such as ALT Input, BATT Output.
Use diagrams to help trace your car charging system.
