Alternator for Freightliner M2 112 DD13 Detroit Diesel 2013-2017 8749 8600078
Functions of an Alternator The alternator converts engine mechanical energy to electrical energy, charges the battery, and stabilizes voltage to power vehicle electronics. 1.Power Supply to Electrical Systems：Converts mechanical energy from the engine (via a belt drive) into alternating current (AC), which is rectified to direct current (DC) to power in-vehicle electrical components during engine operation. 2.Battery Charging：Maintains the car battery’s charge by replenishing power consumed during startup when the starter motor draws heavy current and compensating for energy used by electrical devices. Prevents battery depletion and ensures reliable engine restarts. .
