You need to check and make sure the alternator is charging. You could have gotten a defective one or if you got a used one it may be bad. Get a digital multimeter and with the vehicle off check the voltage at the battery. Should be 12+ volts with a charged battery. Start the vehicle and check the voltage again, should be 13-14 volts or better. If no voltage increase check the big output terminal (thick red wire usually going to it) at the alternator and see it the alternator is putting out voltage. If no voltage other than battery voltage then the alternator is not working. This is assuming that the alternator has an internal voltage regulator (most now do). Without year/make/model/engine size it's very hard to give you decent direction other that generic help :-) **I am assuming you have tested the battery**

Brake lights dont come on when braking bulbs work fine?
The right brake light does not work on 1999 Ford Windstar. Tail lights and blinking light works. Changed bulb more than once, changed the plug in where the bulb goes but it still does not work. The tag lights are not working either.
