[cargirl2003]

okay so here is my problem. It all started with my car not starting. So found out it was for some reason there is a issue with the ignition switch so my friend bipast the inginition switch and linked the starter and a push start button so my car would start properly(saving some money ). then my starter went so I replaced that. everything was working well and now6 months later the lights were diming and the car stopped working so I replaced the alternator and that worked then the lights a month later exactly the same alternator went again. so a few days later the battery goes out. replace the battery the car works again. Now then a month later the alternator goes AGAIN for the third time. so replaced that and it worked for like 2 weeks. now the lights are starting to go dim and the radio panel didn't light up and the seat belt like flashed and the car started to sputter after driving it on the freeway for a bit. turned it off and then back on the radio panel came back on so I drove it home and the light went back to full power. Any clue what this could be? I did not replace the belt when I did the alternator so any help would be awesome please!!

You need a voltmeter to test the alternator output and the condition of the battery. The alternators you have been installing, were they new, rebuilt, or used from a junk yard?
