The charging system on the 1986-89 W124 chassis is under-powered. IN 1990 MB installed a much more powerful alternator. AT dealer & many indenpendant shops that early 65-70A alternator is replaced by the later 80+A alternator. The only part needed to install the larger alternator is the wiring loom MB part number 124-543-45-26. The alternator is 008-154-48-02-88 OR Bosch AL66X
