How do you tell if your alternator is done?
The alternator is here to give power to / recharge the battery while the engine is running. the alternator, when wired correctly isn't charging with the engine running, then you can tell it is not working anymore. how to know : ideally you'll need a volt meter to controle voltage on the battery +/- plug while engine is doing ~1200rev. bit more elaborated : follow the + cable from the battery to the alternator connection, then with the engine running mesure voltage between the alternator connection and any negative ( - ) spot that you are 100% sure of (i.e. the head of a bolt screw onto the car) a good alternator will give you a reading around 14 for a 12V system (most popular) What happen when the alternator is not working properly : Your battery keeps on diying.

1990 ford tempo had sudden power loss amp light on dim lights. What is the cause?
The first thing that I would check out is if the alternator is working correctly. If you put a meter on the battery posts you should see a DC voltage of aprox. 12.5-15. If you see lower than this then your alternator is not charging the battery correctly and will cause dimming and then cause a dead battery. If this is good then look for corroded contacts on battery cables and the starter, or silinoid. I hope this helps you a little bit.
