Need help with system check tach

Question

I have a 97 115 ocean runner with a system check tach. When I start up i get 3 lights and a beep no oil,hot,chk engine no light for the low oil. from what I hear the v 4 engine does not use the ck engine light so I am guessing that my ck engine light is actually my low oil. It keeps comming on with a 20 second beep. I topped off my oil tank and still happens. How can I disconnect that annoying beep. I found a plug on the motor but when I disco that all my guages go off. any help please?

Answer 1

I would think the float sensor has failed in the oil reservoir. Beep every 20 seconds or so = oil level in tank has dropped to 1/4. Check wire connection at tank.
