What part runs when key is on Acc and Ignition switch is on?

[Chexi]

Okay, so I took the boat out (99 Air GT-40) 2 days ago (changed impeller and got her ready). She ran beautifully. But, when I dropper her off at her storage unit, I forgot to turn the battery switch off. I turned off all the dash pencil switches (except apparently the ignition switch, whose little light seems to be burned out). When I went back to work on her yesterday I could hear a faint electrical motor or the like running. When I turned off the ignition breaker/switch, it stopped. The key was on ACC. It was not the blower and the bilge breaker was off and she was drained, so I don't think it was the bilge. I ran a few tests and found that every time I turn the ignition switch on I hear this little noise. Is this the fuel injector? If not, what runs automatically and constantly (at least with key in position other than full on position) when the ignition breaker is on?

the fuel pump should prime for about 3 seconds but it will shut off. Does this noise run continuously?

Nothing should run continuously and leaving the ignition breaker on should only be providing power to the clock. If "something" else is running, then you have a problem. Need to locate the source and find out what is wrong. Might want to put a meter on the battery (+) to see how many amps are being pulled with everything off. More than a few miliamps and you have a problem.

BTW, Is the ignition light off even when the key is "on" (and the ignition breaker is on of course)

You have a gremlin. Nothing will run with the key in the accessory position except the stereo or maybe perfect pass if the dealer installed it that way.

Gremlins! Oh no! I'm heading there in a few and will see what I can find out.

i'm not sure what the motor noise is but the bilge pump will run every 5-10 minutes even if the bigle is dry. it turns on, runs for a few seconds to see if there is water, and then turns off.

I know this doesn't make sense if your bilge breaker is off but it is possible that it may be the bilge.

[Chexi]

Well I tested it today and heard nothing this time. Oh, and yes David you are correct, the ignition light did go on when I turned the engine over (and stayed on). It is only not illuminated when the engine is not on.

[DavidF]

Ok here are some thoughts:

Your ignition breaker light is functioning normally. If the light stayed on when the key was "off" then your battery would be drained if you left the ignition breaker on. Normally, leaving the ignition breaker on is not a problem with battery drain.

Another possibility could hav been that you had the automatic bildge breaker on and the manual bilge breaker off. Do our boats even have this? My '93 (sold this past saturday!) does. Anyway, if it does, the bilge pumps will run for several seconds everytime power is applied (i.e. turning on ignition breaker). They operate in this maner to sense if water is being pumped or not via load/amp draw.

Do you have a float operated bilge and the float is stuck?

What about your blower?

A lot of accessories were added by the selling dealer when your boat was made. Some accessories may have also been added by a regional service center. Because of that, there is no standard way all 1999 Correct Craft boats were wired, or set up.
I believe your boat has the following breakers, in two rows. Blower, ign, bilge, anchor lights, navigation lights in one row, and courtesy lights, accessory1, accessory 2, accessory 3, and accessory 4 in a second row.
Nothing works unless you turn on the ignition breaker.
Usually heaters, and shower pumps are wired into accessory 2, 3, or 4.
About the only thing I would expect to find on the accessory position of the key would be the stereo.
I have found boats with the heater "hot wired" into the battery, and totally bypass the accessory switches on the dash.
I am going to guess your boat has a heater, and the low speed of the heater motor was wired into the accessory position on your ignition switch.
The heater on an Air Nautique is usually just in front of the drivers feet kick panel. You might also be able to get access to it by removing a panel under your starboard rear seat cushion, in the bow area.
The stock bilge pump works by this logic. About every three minutes, it switches on. If there is water present, it loads the bilge pump impeller, and the pump stays on, until the water is gone. The bilge pump impeller then speeds up, and the pump "knows" the water is gone, and it switches off. The bilge pump also comes on whenever power is first applied to it, or every time you start the boat, with the bilge pump breaker switched on.
There is not a float on your bilge pump from the factory. Someone may have added one later. Your Air Nautique probably has two bilge pumps, one by the motor, and one in the stern. If you want to remove an much water from the bilge as you can, switch the pumps on when the boat is a a slow wakeboard speed. The water will go to the stern of the boat, and the front pump will be dry, and just the rear bilge pump will run.

It's for sure not the blower, as I tested that and the blower sounds different. It's also not 1 of the bilge pumps (the manual), as that also sounds different. The heater does not work unless I turn on the heater breaker and the fan switch, so that's out. It could be a 2nd automatic bilge. It sounded like it was coming from the stern. If that is the case, then I guess I am not worried, as those I would imagine are designed to come on and off again a lot.

The audio amp fan is a good guess.
I had a problem with my bilge pump a while ago. Remember, the pump senses a load, and stays on until the load is gone, that is the water is out. My bilge pump got some bilge gunk in it, and that dragged in the impeller speed down far enough that the pump stayed on, thinking it was moving water.
We can keep guessing, but maybe it is time for you to spend some time emptying out your boat, and looking for what is running. A previous owner could have installed just about anything.
Have you checked all the ballast pumps? I think there were six pumps with Correct Craft boats of your vintage.

Check your ballast pump switch as the pump if wired to factory specs could be operating and causing the noise.
