Really need help before i burn this pinball

When i turn it on and push the reset button it all resets and the reset motor continues to turn and it also counts all the bonus counter up then if i do that a couple of times to try and source the fault if blows the step down transformer fuse?
Could this be a short in the pinball transformer? I'm at a loss, is there tech at the ballarat area i'm willing to pay because i'm over it
