Pressing the credit button in the middle of a game adds a player.

Is it supposed to do that? I expected that it would reset and start a new game.

Example: Two player game. Player one is on ball two. Press the credit button and the game adds player three. Seems like it would reset.

Yes. I meant Happy Clown. Long day.

Thanks!

Cleaning the switch seems to have fixed it.

Of course, now the motor won’t stop spinning, but hey, it’s a hobby.

Digging back into it when I get time.

What fun. Reset bank coil now fires properly and the motor stops spinning.

The add a new player instead of resetting the game problem is fixed for the first game after power on, but not thereafter.

Power on. New game. Score some points, drain the ball chute switch, press start, it resets. New game. Score points. Drain ball . Press start. Adds a player.

Still digging. Gotta be that same relay.

Today is my lucky day.

The ZB relay wasn’t firing at all. It was never closed during game play.

But, now it does. No idea what I did to fix it.

No obvious loose or shorted wires, but no matter. I’m smiling and moving on to the next issue.

I spoke too soon. Alas!

ZB isn’t firing when it should. It’s intermittent.

Looks to be related to three one point contacts. Is that referring to the 0-9 wiper unit? Or the 1 pt relay?

Sure is hard to see that happening on these really short, stiff Gtb relay switches.

Fixed. Thanks.

On to figuring out why the credit reel isn’t firing .

Credit reel wasn’t firing because someone had bent open all of the switches on it. Go figure.

There is one switch missing a wire. The wired blade has a purple wire. The other blade has solder, but no wire. Everything on the unit works. There's no purple wire going to either coil on the schematic. There is one line going to the subtract credit coil with no wire color. It goes to the total plays meter. Guess someone didn’t need to count plays. With the credit unit switches bent open, there was no danger of racking up plays on the meter. Again, go figure.

Only one more issue. The roto target needs to be cleaned up. It works and scores, but it doesn’t really lock in.

And to think, this was the estate sale game that seemed to be working just fine. Either way, the price was right. and it came with a bucket of assorted tokens!
