Common Reasons For A Replaced Alternator And Battery Failure
When your car’s alternator and battery have been replaced but the car still dies, it can be incredibly frustrating and perplexing. Fortunately, there are common reasons for such failures that can be troubleshooted to identify the problem.
Defective Alternator
If a newly replaced alternator is defective, it can lead to continued issues with the car’s power supply. This can result in insufficient charging of the battery, causing the car to die even with a new battery in place.
Faulty Battery
Even after replacing the battery, if it is faulty or not holding a charge, the car can still die. A weak or defective battery will not provide the necessary power for the starter and various electrical components, leading to recurring issues despite a replacement.
Electrical System Issues
There may be underlying electrical system issues that are unrelated to the alternator or battery replacement. This could include wiring problems, faulty connectors, or issues with fuses and relays, all of which can contribute to the car dying unexpectedly.
