my battery on my '99 dakota isn't being charged as im driving. thats mean my alternater is done right? is there anything else it maybe? also theres an ad on kijiji for a '93 parts truck with a 5.2 in it, would the alternater fit my 3.9?



thanks for any help

Edited update: truck seemed to have fixed itself, drove into town today and everything was great, 14.6v charging. got in it to come home and i noticed it was only putting out roughly 10v according to the dash gauge. sure enough by the time im rolling in the lane the battery has been run down. so i grab the multi meter to check things over, checked the fuse. seemed fine, checked the battery and got 14.8v . so i left it to charge, and just got in from pulling wires and spraying with electronic contact cleaner. could it just be some corrsion and loose contact points?

 

Pull the alt and get it tested to be sure you can get it done at almost any parts store. You might as well get something new why get something that might or might not be good.

 

i had a similiar problem a few months ago i took the alt out and had it tested and it was fine. turned out the battery just wasnt taking a charge.

 

figured i could pick one up out of a scrapper for little more then pocket cash. trying to save as much money as i can for gas and insurance.

the battery charges up and will hold it when nothing is draining it ( like lights while your trying to make it back into the driveway ) sounds like its going to end up at the mechanics again, i had it in there before the weekend because it wouldnt fire and start, but he couldn't recreate the problem so i got it back and have driven it a grand total of 5 concessions lol thanks for the suggestions.
