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!
