When alternator output drops, the battery tries to carry the load—briefly—and then fails early. Symptoms include:
-
Repeated dead batteries
-
Battery or charging warning lights
-
Flickering headlights or dash displays
-
Random no-start or electrical glitches
Replacing the alternator fixes the root cause, not the symptoms.

I couldn’t install by myself and hired a mobile mechanic.He pointed out that the bushing on the one bracket needed to be pushed out to get the alternator in the correct position.It might be helpful to put a note about this in the box.It does work though after installation.
