hey... i have a problem lol... my batt light came on the other day and i noticed that my alt wasnt charging.. so i went and bought a new one and it still wouldnt charge... so then i changed my engine harness and still nothing.. i am clueless at what it could be.. can any one help me??? please and thanks..

 

I would check cable connections and I would also have new alt tested. I bought a new alt put it in for 2 days and then batt light came on and I had it tested and it was junk. Duracrap built to fail!

 

Same thing happened to me. It ended up being the power wire to the fuse box loosened up and began to corrode. Im with toad on this one, check all the wiring

 

ok thanks alot guys.. do you think it could be the fuse panel in side the car maybe?

 

i would check the power wire going to the fuse box in the engine bay

 

kk

 

Check grounds, and check for corrosion on the battery terminals as well. All can cause problems. Also, check for proper tension of the alternator belt, seems simple, but it can be missed.

 

You replaced the entire wiring harness? Damn.

 

i would check the alt because if you got it from napa... they have been producing alot of faulty ones..

 

i didnt change the whole harness i have just changed the front section... the mid section is next tho czu i have done all of the above still nothing

 

this might be a stupid question but did you check the battery? A bad battery will kill a brand new alt.

 

Just another suggestion for you, touch a wire from the alternator housing to the head and see if your voltage jumps up. Some alternators have internal grounds and some have to have the housing grounded to the engine (even if they'r both for the same car).
