I agree with you you it must have been the engine/BATTERY. when i replaced the battery the first time I must not have let it charge now look with a BCR installed. The old battery was a green one and it showed 8.8v at the battery as well as the backside of the board where the wires hookup. The battery must do more than just the sound. now when power off the track the sound goes for about 5 seconds.
Again Thanks to all for your input
