the other day my alternator battery light came on. then shut off so i was going to go home but i was pretty far. a few hours later the light came back on and stayed on for about 1.5 hours. and then the car died. i tried to start the car. it started but it would only run in idle. as soon as i hit the gas the car would die. it did this about 6 or seven times. so i took the alternator and had it and the battery tested. battery was dead, and the alternator tested bad. so i charged the battery and replaced the alternator. now the car will not start at all it just turns over. kind of at a loss no check engine light. or any other lights coming on. it might sound dumb but i was told that there might be some sort of reset procedure that is required after trying to start the car so many time unsuccessfully. or coincidentally something else might have gone wrong at the same time as the alternator.... what can i test or try....

Take your car to a MB specialty shop, it will need a MB SDS diagnostic tool. There could be quite few things, like throttle adaptation or immobilizer problem, etc..
When a problem like this happens stop driving and don't keep starting it with bad battery or alternator. You could cause serious permanent damages to control modules.
