Sometimes the gauge showed me 12V and sometimes 9V or 16V.
Of course when it showed me less than 12V I was unable to start the engine, but when it showed me 12V or more the engine started fine.
I fact it was the regulator (which should be between the generator and the battery) who was out.
Changed this piece and no problem more (keeped the same battery)
Thanks for your tips! The volt-meter, so far, shows 12.5V for all tests. Dont know if it's the same problem but I will discuss with the MB services guy on Thu.
