The problem hasn't been solved. The connection from the starter relay post, through the fusible link, through the bulkhead connection Z and to the ammeter red wire was checked and is good. Before I started this post I completely disassembled the connectors on the engine side from the bulk head connector and looked at each connection and cleaned up the Packard 56 connectors. I used Deoxit on both the male and female connectors before I reassembled the bulkhead connector.
