Not sure if you have a problem, but here is how mine works!
The red target will only release the orbs if the release light is lit. To do this you need to get the '1234' targets down IN ORDER. There is a setting to have the release light come on and off for the last ball (sw 21 off) or stay on all the time (sw 21 on). The magnet is not linked to the orbs release, it is linked to the bonus collect feature. Often both are lit, so the magnet will then work at the start of multiball.
Hope this makes sense! Great game to play 
Thanks for that, it all made sense.
The Release still won't light but I guess that could just be a lighting issue. I don't have any trouble getting multiball to work only I thought on the final ball it was an automatic 5 ball multiball once the red target was hit. This doesn't seem to be the case. I still get multiball but if only 1 of the orbs is lit i get 1 ball out. Is this how it's suppose to play? I've only played one other Centaur machine before and I'm thought that was how it worked. I could be mistaken though.
