Hello Aarbo, this carries 2 types of alternator, Bosch 150 A, or Valeo 110 A. In the two it has a built -in regulator (which will have to check the brushes of these, the good tightening of the diode bridge. Generally the regulator goes on the back cover of these. If you want to try it, the hot values (15 min. Of operation are enough) are:
1000 rpm = 57; 20000 rpm RPM = 105
