Recently while on vacation my 190E shutdown on the interstate.
The first sign of a problem was the turn signals quit working a short time later the engine quit. I was told that the alternator had gone bad and needed replacement. I would like to try removing the unit and have it repaired .

A battery charger was placed on the battery and the car restarted
and the battery seems to be holding a charge if discnnected from the car.

My quiestions are : How do I losen the belt and how do I remove the unit for testing.
