72 Swinger not charging battery

I had some sleep and now sipping coffee, I've never seen a fusable link go bad but have heard of no charge issues from them corroding. .
the fusible link is connected to bulkhead connector 'J', which directly connects the alternator to the ammeter. The fusible link is usually positioned about 6 inches from the bulkhead connector on the firewall side.
The alternator passes the charge to the ammeter first, then through the fusable link then to the battery.
That's why you see no charge at the battery if the link is bad.
