Quoted from Arcade:The problem seems to be that when you roll over a lit rollover something is making that A relay stick on and buzz really loud. After you hit any working 100 point switch the A relay will return to normal. That is until you repeat this process over and over.
I have also noticed that when it locks on it is not scoring the 100 points that it should.
It will not release until anything else scores 100 points.

The A relay should only fire while one of the 9 rollover switches is closed:

If all of those switches are opening appropriately you may have a short that's sending power the the A coil.

Also check that the A relay coil is an A-9746 and that the 1-5B relay coils are A-1119s. Series coils like the A relay are sometimes replaced incorrectly with other coils which look the same but won't work reliably.

Quoted from Arcade:

I have now noticed that when a rollover is hit that the M relay in the backbox is staying energized.

The M relay wants to see one of the 100 point score reels advance before it relaxes so that's normal if you're not scoring.

You need to sort out why the A relay is staying energized. Next time it sticks on, try gently pounding on the playfield around those rollover switches to see if that releases it.
