Alternator Not Charging

I need some help...i installed a system in my truck after the install i kept getting problems with the battery not charging...i had the 105 amp alt in there at first but when i turned on the system it fried the alt...so now i do not have the system hooked up to any power source and replaced the alt but the alt is not charging the battery...does anyone know why this might be? and help determine what i could do to fix it...the current alt i have in the truck is the 60amp stock alt from autozone...would really appreciate any help

i would check the battery and make sure it didnt get fried as well and also make sure no wires were fried as well.

i checked all the wires and they are fine i also got the battery checked an it is at 11volts what wires need to be pluged into the stock alt i have the big black one and then the two wire plug and then their is a spot for a 3rd wire and i have a red wire that is not connected to anything? do you have a picture of what needs to be plugged in

i dont have a picture. have you checked it with a voltmeter to know for sure its not charging or are you going off the dash light?

checked it with a voltmeter do you think the battery could have a bad cell it is an optima red top...

i had 4 red ,and i didnt like them all went bad ,and i didnt have luck with the yellows either ,now i run exide orbitals ,

it turned out that it was the battery that was bad just went to autozone and it was a bad cell in the battery i have a new one and it works great must have been the battery all along... thanks for the help
