Maxum 2600SE Audiable Alarm Help

[Bullysrus]

Hi All

I changed both my batterys 2 weeks ago, ever since I have an Audible alarm going off twice every sixty seconds.

This happens with the engine on or off.

Also at the weekend I ran the engine, once the engine was at temp I gave it a little Rev, then the alarm stopped.

So I switched it off, then back on again, the alarms started again.

Any ideas as to what the cause could be.

My local dealer cant come out for 3weeks to test.

All was fine before I changed the batterys, only changed them as they was dead.

Any help or advice welcome

Being that this has the newer alarm system I'll have to look for the codes as I do not recall them from memory, I know shrew has the list.

Ok quick seach says open or shorted sensor(s) and requires an engine scan. Did you bump any senser while changing the batteries?

Not that I'm aware, how do I find out where they all are

Go to boatinfo.no and find the manual for your engine then look for sensers on the engine near the batteries.

All,

I haven't been able to get anyone out yet, but after reading I have changed the Idle Control Valve.

So, Now when the engine is running the alarm doesn't sound, but if you turn the ignition on the alarm still sounds and every minute.

So now I am confused even more........Help

The alarm will sound when the key is on but the engine is not running its a test function kind of like the idiot lights in your car that come on when starting.

As long as it goes off once the engine is running it is ok.

Thanks

I get the single alarm, then a double alarm, then it goes off every 2 minutes.

But now when the engine runs it doesn't go off

Not sure but it may be an old fault from the IAC that you replaced. If you had the reader you could clear the code, another method is to temporarily disconnect the battery.

I had that problem while running. Found out it was a bad Idle Control Valve. Make sure you change little filters to as that is what makes the Idle Control valve go bad. Agree with mmwjr, disconnect battery temporary.

Oh I forgot, If Idle Control valve is bad, engine won't idle. That's what happen with me anyway.

Hi

What little filters

Thanks

Lift the cover off of your (carburetor) I know its not the carburetor if you have fuel injection, but you will see a small foam like filter around the back edge. I Did see a picture somewhere but don't know where. Check engine manual. Again, they are a white foam, about 1-2 inches long down in the rear part.
