All lights lighting problems - PeachParts Mercedes-Benz Forum

I have a 91 300E that has a lighting issue. When the engine is running, all lighting, interior and exterior have a constant strobe effect. It's still drivable at night but it's hard on the ol' eyeballs. All the dash lights, radio, everything strobes. When the engine is cut off, everything works fine. Could someone help me? It's about drove us nuts. Thanks

Probably the voltage regulator, have the alternator checked.

Thanks Gilly. How hard is the voltage regulator to change? Is it mounted on the altenator and if so does the altenator need to be removed to change the voltage regulator or can it be done while in place?

It's easy to change, on most MB's can be done with the alternator in place, BUT I'm not guaranteeing it's the problem. 90% sure it is.
