How to Fix Lights Flickering After Installing a New Alternator

AvatarByCarl Frisch

When a vehicle has a new alternator installed but the lights still flicker, it likely means that the alternator is not working correctly. The alternator is responsible for generating power from the engine to charge the battery and run electrical components such as the headlights. If the alternator isn’t working properly, it won’t be able to generate enough power to keep the lights from flickering. This could be due to a faulty alternator, incorrect wiring, or other issues. In order to diagnose and fix the issue, an experienced mechanic should be consulted.

Automobiles: New Alternator but Lights Still Flicker

Common Causes of Flickering Lights in Automobiles

Flickering lights in automobiles can be caused by a variety of factors. The most common causes are alternator trouble, loose wiring, and faulty bulbs. When an alternator is failing, the voltage output may become unstable, causing the lights to flicker. Loose wiring can also cause flickering lights, as electrical current is not properly contained within the wire and can jump around to other areas of the car. Finally, faulty bulbs may be the culprit. If a bulb is not properly connected or has burned out, it can cause flickering lights.

How to Diagnose Flickering Lights in Automobiles

Diagnosing flickering lights in automobiles can be done with a visual inspection and a multimeter. During a visual inspection, areas such as wiring connections and the condition of bulbs should be checked for any signs of damage or wear. A multimeter should also be used to test voltage output from the alternator as well as any other electrical components that may be related to the flickering lights problem.
