Okay. Here's the issue.
2004 SAN 330 Excalibur 5.7
Taking boat out of winter storage today. Fired her up on dry land (water hose connected) to warm up the oil for an oil change. When the boat started up I noticed the oil pressure gauge being a bit erratic. It stabilized after a few seconds so I chocked it up to first time the boat had run since the fall. Content all was well, I stepped away from the gauges to clean and get other stuff ready letting the engine run. Came back to the gauges and oil pressure had dropped to zero and had 'low oil pressure' message flashing. Crap!!! Shut off engine. I suspected it wasn't an actual pressure issue as there was plenty of oil and the engine hadn't exploded. Hooked up a mechanical pressure gauge and was reassured...oil pressure is perfectly normal...thank goodness. I do not believe the gauge is the issue as I got zero on the gauge AND the flashing message.
So-I replaced the sender. Had to order the pressure switch-it arrives tomorrow. Overkill? Maybe. Don't care.
I cleaned the terminal ends of the wires connected to each. Tomorrow I'll replace the pressure switch and reattach the wires.
My question is this...let's assume replacing both the sender and the switch and cleaning the ends of the wires that attach to both do nothing. Where do I go from here? I noticed the switch side of the tee has two wires and the sender side has one. Anything to look at there? Bad ground?
Thanks in advance.
