Hey guys... RCT noobie here (I posted in another thread - got a nice machine for $400 from a family member!) - I'm just trying to work out a few gremlins and I think you guys would be the best place to start (if you have a minute to listen to my rambling...)

My machine is working pretty well, 100% of the bulbs are good, sound is great, machine is in great shape. BUT - (there's always a but...) the ghost door does not trigger... so I thought it was the ghost door, but on a simple test from the menu, found that the door did disengage / engage correctly. So that leads me to believe that the ghost standup narrow yellow target is what triggers this function, but is not working. I went into switch test, and tried simply shorting that yellow switch with a wire to make a connection but was unsuccessful. I have ordered a replacement for it never-the-less as it looked relatively worn, more-so than most of the machine. BUT then I realized as I was testing all of the other switches, that there are three other switches not working, and they are (33, 34, 35 in the manual) Left Ramp Return, Center Ramp Made and Right Ramp Made. All at the very back, all on the clear plastic ramps, in the same vicinity as the ghost button that isn't working. I also could not get these switches to short with a switch test.

This makes me wonder if these are in some sort of series or related to each other? The game is great, but without those switches triggering I'm sure there are great sounds, scores, etc that we are missing out on.

I can't bring myself to believe that it's the actual switches that have failed, as it's these three in the same area, whilst every other one on the playfield works like a charm.

Can anyone possibly help me with a next step / process of elimination?

The other thing that isn't working is the sweeper OPTO on the back right (facing the unit.) So the man gets stuck up and the machine has to do a ball search and reset before play can continue. I see that there's a red light on the unit, so I am guessing the transmitter is fine, but the receiver board is fried. Opening the unit up I see the poor choice in location and insulation on this one, as someone had wrapped part of it in electrical tape to try and avoid it shorting out. I have ordered another receiver board and hope to have that fixed in a few days. I'll put a piece of adhesive insulating tape or something on the back to ensure it does not short out.

Anyways, sorry for the long post. I appreciate anyone who can assist on that group of non-functional switches. I'm thinking it'll really make the game more enjoyable to have everything 100%.

Thank you!

Thank you SpookyRides - I have the original manual, french addendum, etc that all came with the unit. I replied to his other post as well, that these are indeed all inline. That being said, they are inline with the OPTO that has failed, so I'm guessing there's a 'hole' in the circuit that is causing all of these switches to not register? Hopefully my replacement receiver board will come in this week and I'll find out. Would be great if that one piece fixed all of these at once!

Thanks,
Adam

Fixed! Replaced transistor Q5 which was common to all of these failed switches. It had blown when an opto shorted out before I bought it. Replaced and fixed the opto, tested good. Removed the CPU board and saw that Q5 was blown (front looked fine, but back of board had carbon and was slightly burned.)

Next day Amazon delivery of some transistors and this thing is playing 100% now. And it's a LOT more fun.

Thanks all for the assistance!
Adam
