New alternator, new battery, and new A/C powered battery charger. Car can only stay charged for a week at a time. The alt. will not charge the battery so I have to charge it from the wall. I have checked all wires and fuses: good. I have replaced the alt. 3 times with no luck. The alt. is only pushing out 12 volts which isn't enough, but a store to remain nameless says it's not the alt. I love to work on cars, but I've just hit a wall and would rather not take it to a shop to get fixed.

Hello,

This could be a wiring issue. There is a fusible link located in the fuse box, it could be blown and that is what triggered the no charge issue.

I have attached the wiring schematics below.

Please let me know of any questions.
Thank you.
