Can anyone tell me how the centre spinner on the playfield should work in relation to all the lit numbers being made and the centre special is then lit?
The side alternating specials award a replay as they should, but how is the lit number on the spinner supposed to award a replay? My machine will spin and a number lights up where the spinner points to it but no special is awarded. Or does it mean that if, say 4 is lit, does the ball have to make the ( now unlit) 4 to win a replay?
Thanks!

Thanks for these replies. Well, it certainly scores points as its hit by the ball Electrocute and the flyer's first statement is correct but the second statement differs from what I'm getting. I will take another look at it today and get back to you.

Thanks for replying.
That's pretty much what is happening, yet when the lit number on the spinner is made ( centre special light is on too) I get points awarded but no special is awarded. The spinner lamps alternate as the pops are hit, as do the side drain specials so that is correct.

I'll dig deeper today and check the spinner's relay again. Has to be something in need of adjustment, etc.

Fixed it! After some more head scratching, I first checked the stepper control relay after unplugging it from the playfield and examining it on the bench. Nothing untoward with it ( I had previously serviced it during overhauling the rest of the machine) so I moved onto the spinner's circuitry which again was clean and tidy. But, from manually moving the spinner on the playfield to the corresponding light, with special lit, I got points only. However, if I moved the spinner slowly one step at a time, so say 2 was lit, 8 or another random number awarded a replay. Untightening the 2 fixing bolts on the spinners disc underneath and rotating it one step at a time, and testing again, after a few more steps, it awarded the replay correctly to the lit number.

Basically, I had the disc in the wrong position yet, as much as I can see anyway, theres no marking to show where it's supposed to go. So if your machine is doing the same thing, look here first!

Thank you to all who helped out
