Hello, my mother drives a Smart Fortwo cabrio Bj2001 54Ps 599cm3 Unfortunately, after 2-3days of service life, the car pulls the battery empty, so you can no longer start the car. If the car is moved daily, it always starts. (Speaking in my opinion for a working alternator) The alternator was changed in April 2016, the battery is also relatively new. The vehicle was in the last 5days at a Bosch service, there unfortunately you could not find a Feh The guess of the fitter is either the starter or the alternator (which is relatively new), but to determine this one still has to lower the engine.. that was too much effort for me. Do you have ideas or typical electric motors with the Smart? Thank you in advance! Peter
