Quoted from BobC:Center Ramp Inside House Reject Issue,
advise please.
My EHOH is at a friend’s who took delivery for me due to my current health issues.
And I’m unable to travel.
It’s being reported that shots going up the center ramp into the house come back out down the ramp,
and they think the ball is “hitting a switch” incorrectly, which is out of whack inside the house.
Does this make any sense?
I’m trying to get more specific details from them.
Advise appreciated for now.
Thanks!
BobC
Sorry to hear about your health and machine issues. Hope both can get cleared up for you soon. The balls rolling back down the ramp at the start of a haunt seems to be a standard issue. Here's how the ball hold for the start of a haunt works:
1) Haunt is qualified (3 shots through the house or backdoor skill shot) and the diverter (metal plate) behind the house lifts to allow the ball to go into the subway behind the backboard.
2) With a haunt qualified, a shot through the house is supposed to go into the subway and stay there, held in from going out the other side of the subway by a post. After video clips play the haunt starts with the post raising up to release the ball into the pops. There is an opto inside the subway just in front of the post to tell the machine there's a ball waiting there. The only mechs in the subway are that opto and the post that keeps the ball from going immediately out the exit and into the pops.
The shot through the house seems to come back down the ramp for a couple possible reasons:
1) The ball catches a bit of air off the ramp into the house and doesn't make it into the subway entrance.
2) The ball goes into the subway entrance but hits hard off the back wall of the subway or hard off the post in the subway and bounces back out the subway entrance.
3) The shot is a bit weak and doesn't make it to the subway
A change in pitch may help #1 (ball catching air off the house entrance ramp). #2 (bouncing back out of the subway) is definitely helped by adding some padding to the inside of the subway where the ball first hits the subway wall after going through the house. Scorpius showed adding velcro in this post:

Taking the subway off to put the velcro/padding in isn't too bad. It's all done behind the backboard. You need to:
1) Remove the coil and post that goes into the subway from behind the backboard. First unplug the coil (I recommend using a sharpie to mark each side of the connectors so you remember which plugs go back together).
2) Remove the opto bracket from around the subway (First unplug the opto cables).
3) Remove the subway, add the velcro (2 or 3 layers for enough cushion) inside the entrance as in Scorpius post, then screw the subway back in.
4) Replace the opto bracket and plug it in. After you screw the bracket in a bit turn the game on and go into switch test mode. Use switch test to confirm you have the opto aligned properly and then screw it in tight while holding it aligned properly. If you don't use switch test to guide you on this it's can be very difficult to get the opto lined up correctly.
5) Replace the coil + post and plug them back in.
I did this on my machine and it reduced the amount of balls rolling back out a lot. It's not going to be 100% because some shots just won't be able to be held, but the ones that should be held are now being held. Hope this helps. Good luck.
