There's one last thing to do, one last modification. It has to do with the flippers. Basically during Haunted House multiball, you need *all* the flippers to work at once. Because when the U relay pulls in (ball on the lower playfield), it turns *off* the main playfield flippers.
I argued with Pascal on this point too. He insisted that he needed to add another relay, the Z relay, to make this all work. I told him he was freaking nuts to do it this way...
And if you read Pascal's instructions on this, it's freaking complicated what he wants he wants to do! ...Add a Z relay and modify the existing relays. MY GAWD WHAT A CLUSTER SCREW. I'm sorry, I just can't do it. I mean i started to do it... but then thought, this is freaking crazy. I read Pascal's instructions 10 times, and just thought, "this is freaking nuts"... I started to buy into his crap, and took the 3 relay bank, and modified mine for a 4th "Z" relay...

What mess! I said to myself, "self, this is NUTS, there has to be a better way!" And sure enough, best I can tell, there IS a better way...
What I did was to modify the existing lower playfield U relay. There's two switches on that relay that when the ball goes on the lower playfield, it turns off the main playfield flippers when the U relay energizes. But WHY does it do this? what is the point? I mean there are separate flipper buttons for the main playfield... why turn them off??? WHY???
Well there's NO point in this. And best I can tell, unless someone can explain this to me, there's no good reason to do the Pascal Z relay modification. I just don't see the point. I mean I'm sure he has a good reason for the Z relay, but what a cluster screw! It's a shite load of work to do this Z relay modification, and i really can't justify it.
Instead what I did was modify the U relay. There's two NC switches that open on this U relay when the U relay energizes (when a ball goes to the lower playfield, or when you're in Haunted House Multiball)... what I did was just bend those NC switches so they never open. Basically anytime the U relay pulls in (ball on the lower playfield or multiball), the main flipper buttons still work...

Right now this is the only modification I do for the main playfield flippers. Until I can come up with a good reason to add this Z relay. I will play the game a bunch and see if i can come up with a reason for this Z relay... But for now, this is a MUCH easier approach with less modifications and changes from the original set up.
