Hello,
I have 2004 Mercedes w211 e320.

I’m not getting any power and I can’t turn the key. I checked the battery but it has power. I also checked all relays and fuses with a multimeter.

I don’t get light or accesorios power. Can’t turn the key or anything.

Any ideas on what I should check next or what the problem might be ?

battery good, alternator good, dashboard lights on, car does not start except booster. any suggestions????

[natesrawharvest]

Brand new battery, brand new starter, no corrosion on battery terminals or cables, all fuses are good. Cabin light turns on and "open door" dashboard light. Can't even turn on the headlights. Zero power or dashboard response. Can't test alternator without turning on car. What could it be?

New battery, everything tested good but no power is going to my car whatsoever, not a single light in dash will even go on
