Annoying Warning Buzzer

[Ralph L. Fullenwider]

A couple of thoughts come to mind:

With key switch on, engine not running, press and hold the check engine
switch and count the flashing lights, this will be the DDEC codes. There
will be two codes displayed, low water level and low oil because the engine
is not running, anything other than that might well give you a clue.

The jacks have all ready been mentioned, this will cause a buzzer.

On the air side, just a stab, do you have the bulk oil fill system? is it
turned on? if left on this will cause a buzzer as well.

Just some thoughts

Safe travels,
