hi

first.load test the charging system ..if you have no load tester,auto zone and most parts stores will do this test for free...it is possible that the new alternator may be bad..

the problem may be the ignition switch.[not the key lock cylinder].it may not be sending power to the alternator to kick on the regulator..please print the diagram below

thanks

please ACCEPT my answer so I can get credit for my work.i don't receive commission unless you do ..I'm not always going to be giving you good news,so please don't let this stand in the way of you accepting my answer.it does not cost you more money.we will still be able to communicate.. Bonuses and positive feedback are appreciated!if you are not satisfied with my answer,please do not leave bad feed back,i will gladly opt out and let another expert handle the question.PLEASE ASK IF YOU NEED MORE HELP
