Chosen Solution
I used fresh batteries on a Big Trak, early 1980’s model, which had not been used in more than two decades. After I program Big Trak, I press GO and all it does is elicit an unending, loud tone. I presume it is “stuck” somewhere. Who can repair this vehicle, if it is worthwhile or possible to repair?
sounds like the motors are stalled. I would work the drive wheels back and forth by hand and see if that frees it up. Also make sure ALL the batteries are fresh. These are real battery hogs.
