You can follow this hose down to your senders.

Circled is the Hobbs Switch. Low oil pressure alarm. The one below it should be the gauge sender.

The funny things that come in my dreams,, Has your oil pressure ever worked? That sender in your picture did not look original.

So the big fat one with the single red wire is the target, correct?
Assuming I've identified the correct thing, is there any reason it should be run through the ships service panel in that engine room? I've been tracing the wire backwards from the helm and it sure looks to me like it's wired into the battery switch panel down in the E.R. It's possible I've got the wires mixed up, though - I ran out of energy before I could put a tester/toner on it to be sure.

Yes, the gauges at both helms worked - albeit intermittently - until a few weeks ago.

While doing some troubleshooting this morning I discovered that the starboard (non-functional side) gauge has 0v when the ignition is on (port is getting 13.3v), which seems like a pretty big clue. I don't know what it means but I know it matters lol.

I remember some 32Vdc boats using a DCv to DCv converter for the 12Vdc gauges. Hidden under the lower helm.
