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
