Moin,moin, I have a problem with the alternator from a Smart 450. The following, to the Smart of a friend of mine was the light engine dead, she was completely fixed and the housing also had a few fine cracks. I expanded the old alternator and we ordered a new one. And today I installed the new alternator. Well, now the problem, the new alternator is not loading and the battery lamp in the fitting does not go out either. It is a Smart 450, built in ’99 , 0.6 liters , 45 Ps… The old alternator was a 65 ampere and had 3 connections, once M6 and twice M5. But it was only a cable connected and it was on the M6 bolt (B+) The new light engine is a 75 ampere,bischen more strongly hurts. And the new light machine also has 3 connections again, once M6 and twice M5. I have the cable again to the M6 bolt (B+) exactly as it was previously with the old light engine. But unfortunately I can’t also use the new light engine.
