On my GP I get two advances of the bonus (left or right) when the ball goes in the top saucer regardless what the red arrow indicates. I always try and watch Youtube videos to compare my game to see if it is playing correctly or not. Here is one that shows it advances 2 when the ball lands in the top saucer.
As far as the spinners, there are little mini steppers for each one under the playfield. Make sure those are clean and work. There should be 3 wires on that mini-stepper that advance the bonus 3 times every time the stepper does one revolution (10 spins). I made mine harder by removing 2 of the wires so the bonus only advances one position when the red insert under the spinner goes from the top one to the bottom one. Basically advance one bonus position for 10 spins rather than 3.
