My battery wont charge.... I went and bought a new ALT and put it on and my battery still wont charge its running off the battery and ive checked everything all wires are good and tight. Any ideas its got to be a wire or something electrical. Any help. Is there a fuse for the ALT??? I couldnt find one.

 

You might have a dead battery, have you had it tested?

 

I havent but when i dissconnect my battery the truck will die,im not sure if these newer ones will run just off the ALT but i know the older ones will run off the ALT. And its a fairly new battery less then a year and havent ever ran it down.

 

Which side are you dissconnecting?

 

+ side

 

Have you done a voltage test on the battery?

 

Yea tested good 12.5 volts

 

It is possiable that you have a bad ALT. Even know its new.

 

Its possible but its been tested. Im lost in the sauce

 

Good luck with finding you problem, but I'm stomped
