Assorted Mercedes Alternators

Mercedes-Benz vehicles use highly sophisticated charging systems. Unlike older cars with simple mechanical alternators, modern Mercedes models use smart alternators controlled via a LIN-bus data line or advanced 48V mild-hybrid Integrated Starter Alternators (ISAs). Because the alternator communicates directly with the Engine Control Unit (ECU) and Front SAM (fuse module), charging issues are rarely just a matter of a worn-down physical belt.
