I replace the wire harness that connects to the alternator and the battery and battery terminals also but the car still wont stay running


Did you buy the cheapest alt. you could find ? Did you charge the batt. with the new alt. before you fired it up ? Things need to be tested so that you know exactly what's going on .

The first alternator I bought it didn't work so I took it back had it tested it was bad so I got another one on the warranty had them test it before I left the store it tested good it was the middle priced alternator but yes I also charge the battery

I'm almost thinking that it's something to do with the wiring I replace the three prong plug that goes into the alternator but I think I'm going to have to trace the wires off of that back and test them and see if they're good. Is there a sensor/relay/fuse or something I could check first really don't want to have to mess with wiring I'm not the best at it


The problem may be unrelated to the alt. problem , you should monitor the voltage from the alt. at the batt. to see if it drops at the time it dies because you really don't know why it shuts off . Could be the temp. sensor who knows ? . I found an AC delco OEM supplier because even at the top nationwide brand name parts store I've gotten crappy starters , and calipers

Thanks I had a friend who said it may be a temp sensor also and that it may be unrelated to the alternator going out
