We're back!

After a disaster in our datacenter took down our server, we are now running Pinside on a brand new server. However, things may not work as expected as we are still polishing the playfield and adjusting some switches! We might be switching to maintenance mode a few times. Please see this forum topic for more info.

Picked up my first wedgehead (Top Card) the other day. There are two female Jones connectors in the light box that appear to be unused. Is that right?

#2 6 months ago

Do you have a picture? Some single ones are used to increase or decrease scores in which you win a game.

#3 6 months ago

Yeah. Got one of those too. It has jumpers, etc. But there are two that seem to have no purpose. Thought it might be a wedgehead thing. I'll upload a pic in a bit.

There are 3 plugs lower middle

The score adjust is upper right. Can't figure out the two in the middle.

Chad - Is that a pic of a Top Card?

I could not find top card, as an example I found Captain Card.

Not sure what that plug is for F/S unit?

If you look at the right most side of the relays , there seems to be an open spot.. the F/S unit generally has 2 connectors.

There should be an F relay (AS mini stepper style) next to the L relay in the relay rack. The two connectors are for the F relay.

Ahhh. I see. Apparently it's been cannibalized. Or, did some of these games not come with them? Seems like an easy thing to add/remove.

Will this game work without one?

Does it have other functions besides the match?

#11 6 months ago

It's missing. On this game the F relay drives the I/Alternating relay during the game and the match circuitry at the end of the game.

#12 6 months ago

As Mark notes, since you have no F relay to drive your I relay, your game will not be toggling the I alternating features such as lighting the pop bumper lights and associated elevated scoring or moving the lit special(s) to the other location(s).

And also you will not get any match lights or awarded credits for matches at end of game.

#13 6 months ago

Thanks guys. I can see all that on the schematic now. So I trust the "I" relay is also a part of that unit?

Shame on me for trusting the seller when he said it was all there. Maybe I'll get lucky and find someone parting out a similar game.

#14 6 months ago

No, the I relay is a separate unit elsewhere that is energized whenever F pulses.

EDIT: actually, one pulse to the F relay causes the I relay to pull in (and remain pulled in), the next pulse to F causes I to release. This cycle continues with each pulse of F.

No, the I or Alternating relay is probably in the main cabinet, either on the bottom board or under the playfield. The F relay that you're missing is just a single AS style relay with a small ratcheting mechanism, a pair of small circuit boards and a single normally open switch that connects to the rest of the game through a pair of jones plugs. There are probably pictures of AS relays elsewhere on the forum.

While many AS relays look similar there may be differences from game to game. They could be configured with various cams and switches. So unless you can find another F Relay from a Top Card, you'll want to compare the schematics of Top Card against whatever the donor game the replacement comes from, or photos of the two relays.

#16 6 months ago

Thanks. Found the I relay under the playfield.

#17 6 months ago

According to the Top Card schematic, the missing 00-90 Unit relay (F) has 1 switch that drives the Alternating relay (I), and 2 disks. One disk lights the match number at the end of game (schematic 5B), and the other disk completes the circuit to award a replay if the player matches (schematic 9.5E)

To build one from scratch, you're going to have to start with these parts or a unit like it.
pbresource says they're out of stock on some of the parts so you'll probably need to start with a used one.

Let me know if I can help.

Thanks for the info!!

Peeling back the layers ....

A previous owner has wired the Alternating Relay (I) to follow the 8-K Sequence Completed Relay (Q).

Better than nothing I guess.

Does anyone know why Gottlieb designed that unit to be removable?

It's kind of hard to adjust (some say almost impossible) so having it on a workbench makes working on it a lot easier.
