Alternator or generator is a key part of the electrical system of diesel engines. Alternators are responsible for transferring the mechanical energy from the engine into electrical power. It continually charges the battery while the engine is running. The alternator also regulates the power going back into the battery and prevents overcharging.
Alternators consist of moving parts, so when they get dirty and are subjected to extreme temperatures, those internal components can wear out, causing the alternator to fail.
