I was told by a mechanic when the battery light comes on, it means theres a problem with the alternator and not so much the battery itself, thats what happen right before my car lost its power and died out.
The battery light came on and my headlights started to dim, radio, power doors, and sunroof just faded away.
I tried jumping the car but it wont hold a charge. The car has absolutely no power, I just want to make sure it IS the alternator and not something as simple as a bad connection before i take it to a mechanic.
Thanks for the help.
BTW, i have a 1995 Mitsubishi Eclipse GS, and the battery is about 5 months old, but i was told (by non mechanics) it could be defective battery or the connections are bad.

Usually indicates something in the charging system. Could be a loose wire as well as a belt broken or loose.. Died as the battery ran down. Battery seems unlikly

Getting 3 phase 120volts out of a automotive alternator is not a big problem. Getting 50KW out of it IS, to produce this much power will need a larger engine and more alternators than you can shake a stick at, going with your 840W figure would mean 60 alternators that will blow your $5000 budget. If you are able to connect to the grid it would be a lot cheaper, and if you can do that the power company may provide you with a generator. I work on copiers and once had a TV transmitter station as a customer. The copier was constantly blowing power supplies. The TV engineer got the power company to check out the problem they found that the TV station was receiving an electrical tidal wave when the switching station down the road switched loads. The power company provided the station with a large UPS system that filtered out the surges and also put them on a load shed program. This program gives them a backup generator that powers the station when power company loads get too high and the TV station is taken off line.

A fault with the alternators charging system would cause the battery to go flat.Charge your battery up and if it holds the charge then the alternator is the fault.If the battery will not accept the charge then the battery is defective --open circuit- but the alternator could still be faulty if the ignition light stays on

if it died on you like that it isnt the battery or the battery connections.. an easy test for an alternator is if you start the car with a good battery, and then unplug the battery -the car should stay running. if it doesnt you have a charging system issue. it could be the serpentine belt broke, but short of that its most likely the alternator.

The alternator must in perfect charging (13.5 - 14.0 volt) operation with motor running. Today's electronic ignition systems depend on the above sustained voltages to operate properly.
A quick test of your charging system can be made with volt meter leads across the battery terminals with the engine running.

its the alternator.. One Sure way to test it is, Start your car and while the engine is running, remove the negative battery cable, if the car shuts down, It is For SURE the alternator. If the engine keeps running, then its the battery.

What you discribe is exactly what happens to a car when your driving along and you loose all electrical power, your altenator has failed and your car was running off your battery and quite possibly you ruined your battery.THE FIX; A new altenator and battery. (do you have a warranty on your battery?)

have the battery tested and terminals cleaned and checked before putting in a new alternator... could be defective battery or connectors loose or dirty

I guess you have an 8v. anyway try looking at your plugs maybe that can give you some answers or post what you find and we can try and narrow down the problem.. so far i can only think of the cold start valve going bad, clogged injectors, and clogged fuel filter. and maybe you have a bad torque converter. also throttle cable and accelerator cable out of adjustment
