2000 challenger 2000 continous beep issue. Can't find in the manual

[Mcgann454]

I am getting an intermittent continuous beep from the warning alarm when riding. I don't think it is an overheat problem, but a malfunctioning fuel sender. It only happens when the fuel gauge is at about the 1/4 tank mark or below. The sender wasn't working when I got the boat, but I found where you can solder the fusable link in the sending unit to get it back. I had someone do that for me, but it always was registering 1/4 tank less than was in the tank. I would fill it up and it would immediately show 3/4. The beep is one long continuous beep, not the signal beep.

I had read in a few other threads that when the fuel gets low, it will have this signal also, but I am a premium member and have checked all of the manuals I can find and I can't find a page that has all of the signal beeps on it. Just the one for the overheat. Does anyone know if the continuous beep can be anything other than the overheat?
Thanks,
Mike

On some of the merc boats... there is a low battery and low fuel alarm. If it's a low fuel alarm, you will have a button on the dash, that you can push to turn it off. If you don't have the switch... you don't have the alarm. But yes... it would be a buzzer... and it will come on, around 1/4 tank.

Thanks Doc!
I'll try that next time it goes off.

If it is an overheat warning will that same switch turn it off? I'm trying to diagnose a very similar issue. My continuous beep comes on even before starting the motor, as soon as I turn switch to on.

The Dr is right. The 2000 challenger 2000 has this button to turn off the buzzer for low gas. I'll see if I can find the buzzer codes

ok so I see why you cant find this info in the manuals. there doesn't seem to be any beeper or trouble shooting sections of either of the manuals. but...

the mercury side beeps a continuous beep for over heating. I was able to find that in the m2 shop manual. the user guide for the boat says:

When the fuel tank level is low, a beeper
will sound and the pilot lamp on the
switch will flash to advise the operator.
Press the switch to stop the beeper
and turn off the pilot lamp.
From that point, approximately 10% of
the fuel tank capacity is left.

so it sounds like its either the over heat alarm or the low gas. the oil didn't say anything on the boat side but the mercury side said intermittent beeping. so probably not that. anyway. its also possible that either the gas or temperature sensor is shot vs it actually being over heating or out of gas.

Thanks again!
