Hi all.

New to this site and I have a question. About 9 months ago, my '90 LX 5.0 started acting up. We had just moved and went to the car in the morning and it wouldnt crank over. I had to get a new battery. Since then until about 2-3 weeks ago, I would go to start the car in the morning and would only have problems with it once in a blue moon. Now, its every day or two that there is no juice in the battery. I can tell when the car is getting ready to go out when at night, I come to a stop and the headlights dim when idling and the car acts like it's going to die unless I keep it revved a little. Is this just a simple alternator needing to be replaced?

Thanks!!

 

do you have aftermarket pulleys?

 

its your alternator no doubt about it.
i used to drive this old fart car for a while and the lights were doing the same thing. and then ga ga ga dump the car stalled and i had to push the car 3 blocks to my house. it wasnt fun lets just say that. its the alternator

 

obsol3te,

no aftermarket anything

04mustang,

thanks for the tip...i'll change it :-)

 

Sounds like it's half assed charging. One of the doides took a royal dump. Get a new Alternator.

 

Diodes, sorry.

 

Ya to me too it sounds like youre alternator is about done, Once youre alternator dies it grounds youre battery to lose current.

 

Alternator def but wouldn't hurt to check out the battery also.. make sure theres still enough water in it and your terminals are clean
