alternators options

hey, i have 2004 ford focus ZX5 2.0 with a 5 speed manual, i hav had to car in my name for less then 4 years, and in that time, i hve gone through 4 alternators, oddly enough the car always ends up shutting off between the same 2 overpasses on the 401, but seeing ass i am a student and money is tight, i only replace them with used ones from scrap yards, so i want to rip it off like a band aid and just go all out on one that will last a long time, do its job as good on day 500 as day one, any suggestions ford brands to go with?
also, im wondering, has anyone else had problems similiar with there alternator?

well the issue is that it went bad and then you got a used one from a junk yar which there is no real way of telling how long it could last.

check out the local parts stores there and see what they have. you dont want the cheapest but dont need the most expensive. somewhere in the middle will do fine.

I would go with a motorcraft alternator for reliability.

I think you must have a problem that is causing the alternator to output more than it should and killing them prematurely. This is an amateur guess, but I'd worry about the wiring between the alternator and battery, if you had a voltage drop in that wiring the voltage regulator might command the alternator to work harder than it should to make up the difference and subsequently kill the alternator. I've never dealt with a problem like this but it sounds more likely to me than a bunch of good alternators dieing so quickly.

You probably need a new one, but I doubt it will fix your problem long term.

they werent all good alt, they were all used junk yard alt. begining of that name being junk, meaning that they worked but no way to say how long. if it was an issue with something causing the alt to work harder it would mean he would need to replace the pcm in which isnt cheap. he would have also had other issues such as sudden voltage drop causing his headlights and dash lights to dim randomly. not to mention his heater or radio loosing power for a quick second. wouldnt have to have a voltage gauge to see and issue such as the pcm going bad.


get a new alt and put it on. if you exp any issues with lights dimming or the stereo cuttin out then look into a pcm issue.

if the alt was to go bad then there would be dash lights to come on such as the battery light and check engine light along with all the lights slowly getting dimmer and dimmer. its from the alt going bad and the battery taking all the strain. might want to have the battery tested and maybe replace it to.

what you need to look for is lights and stuff randomly dimming and the heater slowing down then picking back up or stoping all together and then turning back on. randomly as in it does it for a few seconds then goes back to normal for then randomly does it agian.

like i said before, each time it has happened my check engine and batt light flickered maybe 5 times about an hour before the car died, and i did check my battery, it is a newer one from last summer, top of the line, has a life time garentee on it so im not to to worried about that, just im guessing the alternator dies a few miles before cause when it shuts down, i loose heat, air, power windows locks and power sterring, thats i drive inthe left lane as much as possible whn on highway, but when the car is stopped, i cant turn it whatso ever, radio ight go for 5 minutes if im lucky,

ya i have to do a lot of work to the car this summer, so i will definitely have to look at all possibilities for why they keep dying on me, if i find a problem i can fix it and then buy a brand new alt
