 Topic: engine warning systemPosted: April-29-2005 at 3:49pm |

the engine warning system in my 86 sn 2001 has been unplugged ever since i baught the boat a year ago. i plugged it in when i noticed that it was unplugged and it stared going off. there is nothing wrong with the boat that i can tell. what does the warning system monitor? how can i fix it? it is probably just a short or bad connection. (i hope)
Thanks, Chris |

I think it is to warn if the motor is getting too hot. It could be a temp sensor gone bad.

It will let you know if motor is too hot, volts are too low, or oil pressure too low.

More than likely it is caused by a bad ground. Mine has started to chirp when the blower is turned on. My plan is this weekend is to disconnect the cannon plug and then connect the pins with a jumper wire until I found which wire in the system is setting off the audio. That's where I plan on starting.

the oil press is setting it off. the oil press guage shows around 60 psi. i checked the volts at the sending unit, guage, and the wire going from the guage to the alarm they all read around 3.8-4 volts. why is the alarm going off of the guage reads 60 psi and the same voltage is going to the guage and alarm? how do i fix this?
Thanks, Chris |

The warning system has its own sensors seperate from the gauge sending units (you will notice two temperature sending units and a sending unit tee-ed off the oil pressure sending unit piping). Check or replace the sensors and clean-up all grounds.
PS: the sending units are grounded through their base. If tefelon tape used at the sending units, the tape can interfer with the grounding of the unit. |

My 87 2001 does the same thing but only when the Nav. lights are turned on. The temp gauge goes up, oil light comes on dim. This is caused by a grounding problem, just haven't had the time to track it down.
Trust the gauges not the lights or noise maker! |
