Ignition issue, paging Del

Has there been any evidence of the ammeter intermittently bouncing? That could indicate problems in the ammeter/ connections, bulkhead connector, or "cough gag" the welded splice

First bad one of those I found in the Navy, in a friend's 68 RR in about 71-72. His ammeter was going nuts. Soon, we had the cluster torn out and the harness all over the front seat, and he was beginning to wonder if I knew what I was doing. So was I. Bad welded splice, and I've seen or heard/ known about roughly a dozen over all these years.

That is rare, but certainly can happen
