I Need Hel Asap

[carguyvr4]

Hey so the other ngiht my car decided to loose power and die out on me ... it was running fine all day and then all of a sudden while driving my radio cuts out and then the lights go dim.. as i drove it and kept the rpms up the lights got brighter and it ran but then when slowing down and coming to a stop the would go dim and it would die... sounds like the alternator so i replaced it and still the same porblem everything goes dead and it wont start.. i jumped it and it'll run but then die.. its not charging... any ideas what i can look at to find the problem im running outa ideas.. battery is fairly new

def sounds like the alternator to me. A cheap way to test your alternator is to start the car and disconnect the terminals from the battery. If the car remains running then it's your battery. Your car should run fine with a bad battery but the lights would go dim.

yea i'll try it idk what else could be the problem its prety weird i jstu spent 300 on belts n alternator n now its not fixed

Make sure the altenator fusible link isnt blown. Its in the underhood fuse box in the corner closest to the passenger fender. Its bolted in but should have a clear top. Also check the wiring that goes to it where its bolted in. Wire should go from the battery, to that fusible link, to the altenator. If its broken anywhere along the line the alt cant charge the batt.

[carguyvr4]

The one where all the fuses are for liek the battery and stuff or somewhere else?

[Stealthee]

That would be the one. It has fuses and relays in it. Next to the passenger headlight.

[carguyvr4]

yea they all seemed to be ok the ones for the alt n battery anyway....

Have your battery tested also. It is something with your electrical system either not putting out enough power or drawing too much.

[carguyvr4]

Alright so the battery is holding a charge and the alternator was tested n bad.. so its replaced and the problem is still happening? the clear fuse ohms out like it should so tahts not the problem where could it be drawing too much from?

[new2mitsu]

did you buy a new alternator, or a used one?

[carguyvr4]

New they tested it for me on the spot to make sure it was good... we recharged the battery and now the batt by itslef can hold a charge but once in the car it jsut gets drained in a matter of 5 min or less it goes from 12v ta below 9 n stalls out the car.. the fuse for the ALT. is good (the clear one they call a fuseible link) that ohms out good and the wires are all carrying volatage... I'm kinda running outa ideas

[talskinyguy]

Are the battery cables hot after you put it in the car. If it is drawing enough current to drain the batter that fast the battery and cables would probably get hot. If not I would still bet on your battery not being able to hold 12v under load.

[carguyvr4]

BUt i bought a new batt. and the same thing still happened.... the alternator was tested at the place and tested good i took the old one there it tested bad.... the relay is fine all the fuses are good... while raising the rpms the batt. voltage went up then once off the rpms it goes back down n dies....when i turned the car off the volt meter read 11.2 running and when off its spiked up to 11.6 where could i be drawing that much power from while running.. radio a/c lights all that are off durring this time....any ideas... my next step prolly 2morrow is to run the car and jsut pull fuses to see if a certain system is pulling a load that cant be handled....I'm running out ideas

[Stealthee]

If thats all the voltage youre running then the alt is NOT charging. Check ALL wires going to and from the alt and the battery.

check the ground from the engine to the chassis i had the same problem so i took the ground wire from my amp and fixed the problem
