You are saying continuous, solid tone or continuous beep or other? Reason I am asking I just had owners tell me it was continuous and turn out to be 4 beeps about every 2 minuets. Try cleaning the cranking battery connections and remove the cables for 5 minuets, then reconnect.
“The world will not be destroyed by those who do evil, but by those who watch them without doing anything” Remember what He has done and remember that He is not done yet! GOD IS GOOD
