is still good and thers nothing wrong wth my altinator . all my cables + & - are clean
same with the battary post . i think i have bad harness .........does anyone have any segustions...( i think thats how u spell it...lol)

 

have you tried changing batteries with one from wal mart or something. i had same problem with a battery that was only a few weeks old.... changed it and its all good. other wise its probally a ground. check the connections on the alternator for glowing red. message me and tell me the deal.

 

ive already tried everything you mentioned any other suggestions?

 

have you tryd to clean the connections on the alternator if you havent already tryed maybe its not geting a charge form that?

 

is the belt loose? Connections clean and tight?

 

check the alternator plug. those the batery light comes on in dash.

 

the battery light doesnt come up..battery posts are clean...and the plug on the altenator is clean to..i just had to replace the boot that goes over top of it
