Replace alternator and battery, and the vehicle is still not charging. I heard there was an alternator maxi fuse on the front firewall. There are indeed ten or more maxi fuses and none labeled. Nor is there a diagram on the cover like the owner's manual says.

There is no maxi fuse that stops the system from charging. here is the alternator wiring diagrams to help you see how the system works. I would check the fuse # 1D in the interior fuse panel, this guide can help. check for power at the fuse with the key on.

Sounds good, that car is a classic and I have always liked working on it.
