Does anyone know how to set the "Balls Per Game" for Andromeda? I bought the $20 set of downloadable manuals, and I tried settings switches 23 and 24 to ON. I also tried switch 28. No luck. Is it set through the coin door switch?

I need to set it to 5-ball play for a pin golf event this weekend.

Quoted from viperrwk:

I can confirm and have tested in the emulator that switches 23 and 24 do indeed set the number of balls per game for Andromeda and that turning both on should set the machine for 5 ball play

OK, that worked - I was counting the DIP switches up from the bottom (Bally-style). Game Plan has pin 1 at the top.

GI is very intermittent on my Andromeda. It comes back if I rock the ice cube relay in its socket, so I'm 99% sure that either the relay or the socket (or both) are at fault. I went ahead and removed one of the relay sockets, which looks burned. One of the relays looked corroded too.


I found the 14-pin 4PDT 24 VDC relays and sockets at Allied Electronics:


Data sheet with more info about IDEC relays:


UPDATE (11-28): these parts all worked great.

How would you clean the inside of an ice cube relay? It looks like the tiny metal reeds are corroded.

The pic below shows what the new relay looks like, next to the old one. The REALLY nice thing about the new relay is the indicator LED. It flashes on and off to indicate the state of the switches. Nice upgrade!

Also, here are the manufacturer part numbers, in case the links above stop working.

Relay: IDEC RU4S-D24 (Relay; E-Mech; Latching; 4PDT; Cur-Rtg 6A; Ctrl-V 24DC; Vol-Rtg 30 DC/250 AC/240 AC)
Relay Socket: IDEC SY4S-62 (Socket, Relay; 14; 4; PCB Mount; 250 V; 7 A; 100 Megohms Insulation Resistance)

And now that my GI relay is working, I've discovered a secondary problem: the GI connector at the PSU board is red-hot. So now I get to rebuild the connector and the header...fun.

[EDIT: finished, HUGE improvement in playfield brightness]

I'm getting 28V (DC) at my coils, instead of 24V. This explains why the coils are too strong. Checking my transformer to see if it's properly set for 115 VAC... [edit: moved to tech thread]

#121 3 years ago

My Andromeda has a 3/16" backglass; it's heavy! I spent most of my weekend resolving various issues on mine, and I'm looking forward to playing it this week.

#122 3 years ago

SealClubber, I have those micro-cracks on mine too, but I just waxed it 3 times after I was done cleaning it with ME. So far the cracks are staying clean - we'll see. When you get yours working, let me know how often the ball hits the glass for you. I'm getting a lot of airballs, especially off that lone left drop target.

In my Andromeda, the coil that kicks the ball from the trough to the plunger lane is defective. Unfortunately I can't identify the part # because the paper is missing. Can someone please take a look under their playfield and let me know which of these coils it is?

Thanks to Pinball Medic for the table!

Question bumped for the day crowd

Quoted from slgerber:

What my Sharpshooter uses is 21-50003B.

Thanks! And confirmed on Marco's site:

Quoted from jeg:

"acquired" this machine from a neighbor moving and wanted rid of it. Has been covered up in my basement for years. Finally getting around to seeing what it is going to take to get it up to par...!

Congrats! I had to drive to NC for my Andromeda, but it remains a favorite. Let me know if you need any local help.
