Re: Warning Beeps
If the horn came on while running, you could be blocked at the powerhead and still have water flow. You should be able to get a sense of the overheating by feeling the head while the motor is running or by checking to see if the paint has darkened on the head. <br /><br />If the horn came on with the motor cold when you turned the key, you may have a short, your ignition may be faulty, or the horn itself may be shot.
