When do you need a dual alternator in a car?
Dual Alternators for High-Power Drain Applications. Alternators are particularly helpful for high-drain vehicle power applications where the vehicle needs to have sustained power output without the engine running, without sacrificing the vehicle’s ability to turn over. Vehicle engineers can approach this from two separate design approaches.
What happens if you have a bad alternator in your car?
