200 EFI Alarm---4 Beeps

[Tim Greifer]

All, last time out and again now testing in the driveway, I am getting 4 beeps. Can you all please fill me in on what I can do to check this out to hopefully rectify this?



Here's what I have checked so far.

--Water in fuel filter, none.

--Replaced fuel filter as well.

--Replaced impeller, just time to do it anyways.

--Checked oil connections at Resevior tank in bilge as well as motor oil tank. Both full, no leaks that I could see. I DO have a brand new oil tank that I can tackle this weekend as well as i have heard that the alarm sensor fault is very common. However, I did disconnect the oil tank on the engines alarm sensor wires and still had the alarm.



ANY help or ideas are greatly appreciated!!
