Fume Detector Problem-gctid371678

[Guest Close Guest]

I have had my 1997 Bayliner Ciera 2355 for the past four years, and have never had a problem with the fume detector. After launching her this past Sunday, the detector ran constantly and the bilge blower ran even with the switch off until I turned the batteries off, even with the engine compartment open. Is it possible that the sensor became faulty, perhaps I miss wired the batteries when I installed them? Any help is appreciated as I am at a complete loss. Thanks, Charl

Put a piece of tape over the sensor and see what happens.

Had a chance to tape over the sensor today, alarm still sounded. I then disconnected the sensor, the alarm still sounded and the blower kept running even though I had the blower turned off at the dash. New sensor time? And is this common for the blower to keep running like this? Thanks again, Charl

You can buy a new fume sensor complete for $150.00 on ebay, free shipping.

Thanks for the link, and I will use it, but still would like to know why the bilge blower keeps blowing even after it is turned off at the dash and the fume detector is disconnected. Any help on this would be greatly appreciated. The blower use to come on once I turned on the batteries, but would turn off after 30 seconds or so. Now it simply does not turn off. Thanks, Charl

It appears that in the case of failure of the sensor the default is the blowers on your unit.

The blowers come on when you turn on the batteries because thats the test the fume detector does upon power up. In the event the detector detects fumes. ( or thinks it does in your case), the blowers are activated till the alarm clears. Just buy a new sensor, it simply plugs in. Simple to change.

Been there done that, sensor is bad. Just replace and the blowers and everything will act normally.

Sensor is a MS2. http://www.starmarinedepot.com/Xinte...ne+Sensor.html

Should take all of 2 minutes. This is a rather easy and inexpensive fix.

Get back to us after installing the sensor with a update please.

Just an update on the sensor, I installed a new sensor, and the alarm still sounded. I started to trace the cable from the alarm to the dash and found where the previous owner must have spliced the cable to install a new sensor. After removing the electrical tape, I found that the red wire was no longer making contact with the red lead from the sensor. I cleaned and reattached the two wires and the sensor and blower are working normally again. Thanks you to all that helped. It is truly appreciated!!

Glad to here you figured it out. Regardless of the wiring fault, the sensor typically only has a life span of about 5-6 years so you were probably due anyhow.
