when you jump start it, is the whole car dead? no horn or windows working? if the whole cars dead, check out the batt and the alt.

Yeah when I have had to jump it everythings dead no power locks or anything like that so battery and alt will be checked first
Checked the battery today at 2 different auto parts stores both if them came out good battery ...alt next?
out of all the different ways to test a battery and/or an alternator, the one i think is best is the kind that you clip onto the battery, and it reads the volts, that test where the battery is, then you start the car and re read the tester, and that reading is the alt voltage. if its charging at 13 or to 14 is good, any lower than a 12.7 and its toast.
every time i remove the alt and take it to be tested, they are wrong, brand new tested good 2 times, and it was bad, a good one i had tested bad, autozone sucks a big one and pep boys aint to far behind.
