So I've got an Asteroids Cocktail i'm trying to get working again. A little background: When I got it, it was missing the power brick and the PCB. I picked up a power brick from another KLOV member, and, believe it to be the early Asteroids/Lunar Lander power brick. When I flip it other there are 2 diodes, not the 4 leg bridge rectifier that I believe is on the later models. No markings on the side of the transformer. On the copper on the underside its's stamped 42-7141-0 and EIA606-932.

I also have a spare working Asteroids Deluxe PCB. Tested working in my Asteroids Deluxe cabinet. I was going to try and get it working with that, before I picked up a regular Asteroids. I know the screen would be flipped, and controls aren't exact, but thought it would work to at least test.

I'm starting with checking the power brick. I think i'm testing correctly, with the following results:

Pin 1/2/3 to 4/5 = 12.17vdc (should be 10.3vdc but unregulated, no load?)
Pin 6 to 7 = 36.3vac (should be 36?)
Pin 8 to 9 = 6.6vac (should be 6.3?)

Pin 10-14 = 87vac (should be 80vac?)
Pin 11-13 = 76vac (should be 65vac?)

Also checked AR and getting 5.3vdc

I think my first 3 are fine. Are the 10/14 and 11/13 correct? Do the seem high or am I testing the wrong pins? Do I have the correct brick?

If I disconnect the monitor, and plug in the PCB, I get 5vdc, tested on the PCB itself. It will play blind. If I plug in the monitor, I get neck glow, spot killer flashes on/off and I get a diagonal line on the monitor. Repeats about every 1/2 second.

I looked here: http://pdf.textfiles.com/manuals/ARCADE/A-J/FAQ - Black and White XY (Version 1.1 dated 7 Feb 02) [English].pdf

Starting on pg 37, I checked all the voltages in test mode, as per the diagram. Instead of 6.68v, I'm getting 10v. instead of 30v, I'm getting 33v. Which all seems higher than it should be.

So I'm trying to start back at the brick, and make sure my starting voltage is ok. Is it high? and causing everything to be high? Or can I not use an AD PCB in this cabinet?

I'd appreciate any help!
 
You can use the AD pcb in there for testing. Did you test the big blue? I you have a working Deluxe machine you can test everything there. Like the monitor and power supply and rule them out.
 
I ordered a big blue, supposed to be here today/tomorrow. I'll test again after I get that installed.

I thought the Deluxe power supply is different than the regular Asteroids ?
 
The start buttons and control panel are different but you can put an ad board in an asteroids and vice versa

So those lines are what they call 'unregulated' which yes, means it can be a bit higher than expected. The 6.6VAC is usually used for light bulb lights, I think? 33VAC is for the monitor?
 
I've made a little progress - I was able to get my cocktail close enough to my Asteroid Deluxe upright, and plug in the cocktail monitor.

I was shocked when it came right up and appears to be working fine. at least I can rule that out. Now I need to retest the second PCB in this setup as well.

I did do a quick voltage check with the same method I used above, and got lower AC voltages. I'm thinking it's going to end up being the power brick. Maybe the big blue will fix that, or maybe I just have the wrong one.
 
More progress!

Still testing with my Asteroids Deluxe PCB in my Asteroids cocktail. My cocktail monitor worked when connected to my Asteroids Deluxe Upright. PCB I'm testing also worked in upright. So that narrowed down to the power supply and the AR. Power Supply I wasn't totally sure about. I tested AR voltage, and thought it was all good.

Turns out, my I had the AR voltage adjusted too high (5.25v) and it was causing problems. Did some voltage testing on the PCB itself, did some more adjusting and got it to work. At least for testing purposes.

Left/right are reversed, and Start is Coin, etc. since the pinout is slightly different, but it did work. As soon as I get my Asteroids PCB I think I'll be in good shape. I was certainly surprised that the Vdc was as sensitive as it was.

One more game brought back from the dead.
