Mercedes 420SEL Replacement Alternator Information


The alternator on your Mercedes 420SEL is a key component of the car's electrical system, responsible for providing power to most of the electronic accessories and also for maintaining a fully charged battery. When the alternator starts to fail it doesn't just suddenly quit all at once, but generally just starts losing its ability to generate reliable power. When this happens you will typically notice accessories such as the radio, heater, air conditioner and windshield wipers not running at full power. The small electrical system icon should also light up on the dashboard, alerting you of a system malfunction.

Most replacement alternators sold on the market are reconditioned units, and PartsGeek.com carries a lineup of quality units for the Mercedes 420SEL, model years 1986-1991. These 80-amp alternators are provided by top name manufacturers like USA Industries, Pure Energy, Beck/Arnley and original equipment manufacturer for this particular part, Bosch.
