Reconditioned an MTH Doodlebug protosound trolley including a new BCR battery a few years ago and had it working like new but last week when I took it to a local display there is a loud buzzing noise from the horn all of the time. Will a new horn fix this or is there a problem in the control board. Thanks!  Bill Makel
