Sounds like an intermittent/poor connection at a terminal block, or a faulty terminal block itself, the way the article read. In my experience working around high and low voltage electronics a lot in both of my current and prior professions, loose connections are the culprit of service requests/general berkery like 90% of the time. Literally in the Doosan Troubleshooting manual for their CNC machines, they mention using a pole inside the 24vDC cabinet and jostling wires to see if the issue(s)/faults can be reproduced.
In reply to golfduke :
That is also a frequent troubleshooting technique for automatic doors as well. Grab a handful of wires and shake them to see what happens.
That's fairly standard practice with all sorts of malfunctioning electric things. Works wonders, too

Some of the decisions they made...

The primary transformer that powered the bridge and engine room was known to have had issues in the past. They redneck'd a welded brace to help prevent vibration. (Feels like that might be a good solution when you are underway, but not leaving port?)
The crew also disabled backup transformers, and the backup-backup generator had a cheapass fuel pump installed that wouldn't turn on automatically with power loss.
I know its just one bad decision after another and not anything actively malicious, but it almost feels like someone wanted the ship to fail at some point
