Why is alternator not working?
Why is alternator not working?
The most common reason that your alternator is not charging is because of a damaged alternator. The way to test if your alternator is damaged is by using a multimeter. You should carefully tap the alternator with a hammer when the car is running in order to test the levels and determine if the alternator is at fault.
Why does the battery light come on after the alternator is replaced?
This would make the Battery Light come on. It is also possible that there is a problem with the fusible link or the alternator fuse for the charging system.
How can I tell if my alternator or battery is OK?
As with most electrical issues, if you know the battery or alternator is OK (because you had it tested), then diagnosis comes down to tracing and testing for continuity from one portion of the circuit (s) involved to the next.
What was the problem with my alternator going out?
I was thinking that the problem was probably the alternator and as I was trying to get to my house the instruments began to go out. First the tach, then the speedometer, and then the accelerator pedal was unresponsive. I was able to limp for a little while, but it eventually totally quit.
Why is the battery light on on my 4.6L?
Broken wire coming off the alternator. It may not look broken but it could be broke inside the insulation. That was the story with my 4.6L. The battery light would come on and off, wiggled the single grey wire and it would turn the light on and off.
