Q
does revving engine help jump start
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Revving the engine during a jump start does not directly aid in charging the battery of the vehicle being jump-started. Instead, it helps by increasing the alternator output in the donor vehicle, which in turn can provide a stronger and more stable electrical current to the dead battery. The primary objective when jump-starting is to use the donor battery to provide enough power to start the disabled vehicle's engine. Once started, the alternator in the previously dead vehicle will charge its own battery. Revving should be done carefully, keeping the RPMs moderate to prevent potential damage to either vehicle's electrical systems. It's more important to ensure good connections between the cables and the batteries and to follow the proper jump-start procedure than to excessively rev the engine.
