    Welcome to Motor Vehicle Maintenance & Repair! When you say "won't start", what do you mean? You turn the key and you get nothing (no noise from the starter)? What do you have to do to get it started again? Which model/engine of MB do you have? Feb 18, 2019 at 13:03
  • How do you confirm battery is OK? Are you load testing it, using a voltmeter or ?
