bolt size on 2000 dodge stratus alternator
The 2000 Dodge Caravan alternator can be changed by removing the alternator belt. Remove the wiring harness from the back of the alternator. Loosen and remove the alternator retaining bolts. Install the new alternator by reversing the process.
A dead alternator is most likely. Maybe the ECM but not likely.
Use a tester to see if the charging system is working properly. If your model has a separate regulator make sure it is working properly. Make sure that your battery is ok, a battery with an internal short can cause the charging light to stay on. The engine computer is the voltage regulator.
The battery light comes on when the alternator is either over or under charging. If the alternator tested good you have a wiring or computer problem. The engine computer is the voltage regulator.
The alternator is not adjustable. The computer controls the voltage output.
i had the same problem! replaced my alternator 3 times! battery light kept coming on, finally took it to an alternator specialist, come to find out my wireing was connected wrong, and the connector was bad, car wasn't reading the alternator correctly causing the alternator to shut down. Got it fixed for roughly 350 dollars but no problems since, suggest brand new alternator not a rebuilt one!
more than likely a loose belt. it's usually a serpentine belt but whichever one is turning your alternator. the alternator itself could also be faulty or not properly charging.
Probabaly a bad sending unit, may be shorting out and needs to be replaced.
It is mounted on the engine and connected to the battery.
Alternator going bad..replace it. Just had the same thing on my 2000 neon
go to a auto parts store like advance auto and have them check your computer to see why it is on. they do this for free. this might give you a idea on why its on. if you havent already.
