Oil Pressure Gauges Only Working in Engine Rooms

[adt2]

The oil pressure gauges at both our pilot house and flybridge helms only rarely come to life. The ones mounted inside the engine room doors work as expected 100% of the time. Before I go down another rabbit hole, is there any chance that's a well known issue with a common fix? All the other gauges seem to work just fine.

Engine room gauges are likely mechanical gauges. The helm gauges are electric. If they are working intermittently, then it is likely that there is a bad wire or bad wire connection. Look a the senders and see if the wire ends are crimped well and fastened tight.

I ended up replacing mine with new Stewart Warner gauges and senders from Sam's. They work fine now. Mine in the engine room are mechanical as well.

Historically half my issues were wires/connections and the other half sender or gauge.

I had a similar issue. I resolved it with restrapping/rebonding my engine room. It’s strange how a floating ground affects digital gauges

Thanks for the tip. I bet you can guess my next question… Where are the senders located?

Look for wires going to the transmission. It will be a fitting that screws in and has two screws on it where the wires attach.

Thanks!
