Alternators
In a charging mission
The role of the alternator is to provide continual charge to the battery while the engine is running. Alternator is driven by the engine via pulleys ... and a belt drive to retrieve the appropriate energy level from the engine according to electrical energy needs.

Stop - Start system diagnostics
Stop - Starts system function relies on many parameters and it will never allow automated Stop- Start if all conditions are not properly set in the vehicle.
Analyze all parameters before changing parts. Think about the working conditions that could disable the system..brake vacuum reserve, electric parking brake, brake pedal, clutch pedal, engine operating temperature, better state of charge, power accumulator voltage, air conditioning and outside temperature, accelerator pedal etc..
