Here is the alternator installed with a boot I removed from a W124.


The 9 blade fan and small pulley are installed.


My upgraded alternator is in place with new (albeit slightly too short) belts. There is more travel room on the adjuster bracket to loosen the tension screw, but the alternator body hits the lower bracket. Once the belts were in place, they were fairly loose and tightened up just fine.


I put a multimeter on my battery and it showed a 13.08 volt charge.


With the engine at idle, the voltage started climbing, showing that the alternator is working and is charging the battery.
