I was afraid of that. All my supplies I have stored are either 9V with not enough amps or 12V with right amperage. Damn. Local used game store only has the same retro PSU I already tried

If I have power supplies that are the same specs but not Genesis actual supplies, could I use those to test with? I dont want to buy 2 1602 Power Supplies (they look a bit costly at around 20 bucks each) to find out its another issue that isnt fixable.....

350MA is what it's labeled as

Having an issue with my Sega CD Model 1 where the unti will seem to power on for a second or two (both red and green lights come on) and it then powers off. If you continue to power on the Genesis attached to the CD, nothing happens until you unplug the system completely and plug it back in or pull the genesis out of the connector with the CD and push it back in. I know after reading varying posts on different sites that the fuse on the Power Board can be the issue, but I have replaced the fuse and it has continuity when tested with a multimeter. I also replaced the resistor that sits to the left of the fuse on the same side of the Power Board and it seems fine in testing. I have tested this with 3 different model 1 Genesis consoles with the same issue happening each time. The connector on the Genesis has been cleaned with an eraser and alcohol to make sure it wasnt the issue as well. I also cleaned all the connectors on the CD (the connectors that attach the main board to the CD, the connectors that attach the main board and power board, and the connectors that attach the Genesis to the Main Board). I am using a 9V RetroVersal Power Adapter for the CD and the Genesis for Power as I dont have a 1602 Power Supply for either. The Power Supply is drawing between 9 - 9.67V when tested. I read somewhere that the CD Unit could possibly cause this due to not being setup right, but I dont remember the specifics or if that is even a correct assumption. Looking for some advice here on what steps I can take next to try and rectify this issue and get the CD working properly. Are there things I can test on the boards themselves?

Thanks man, I will continue to work with it...you mentioned they should always move to the left? Mine has started right a couple times but I know the string wasnt would right as it would immediately either get VERY loose and fall off or pull REAL tight and stop there as teh print head tried to keep moving but couldnt...

I find that mine (right now) when it starts will go to the right or left depending on where the mechanism is when I turn it on...but I dont know if this is due to the way I am stringing it or not? In either case, it gets loose so fast that I have to stop it.

When I am trying to wind these up, if I start on the left side, should the printer mechanism be slid to the far right? Also, when I turn it on once its wound up, what direction should I expect the device to go? I am assuming that since I do the right side second, the mechanism will be to the left side...so should it head right?

I need to replace this Diode in my Sega CD Model 1 to get it working again... The Service Manual says its a diode 1sr-35-100a radial. What exact Diode do I need to buy? This is part D1 on the Power Board of the CD unit...this and the F1 Fuse need replaced and I have the fuse...just need this diode and its working again!

OK, I dont know what I am doing wrong... I tried to wind each side left side first, then right side and I get it wound up and tight. The minute I start to move the printer head back and forth the string gets loose and starts to fall off... I took the pully off the motor as well and tried to wind it up, but cant get it wound and then put back on... Feel like I am screwed, which sucks as if I can just get this part fixed, my Adam should be working!!

One last question....do the strings both wrap in the same direction or are they wrapped in opposite directions on that wheel? I have wrapped it to look like those photos but the minute I move the printer head, the wheel turns and the tightness is gone and the string starts to get looser and looser.

Is there a trick to that or is it just trial and error?

Awesome...thank you for that... Have an issue, hoping I didnt mess this printer up.. I took some parts off to clean the printer completely....when I did the wheels and the string that are on the sides of the printer mechanism came off as the wheels came out, focing the strings to fall. the string isnt ripped or cut, but not setup. I tried to wind them back up by getting all the string out until the end of the string was all that was attached to the center wheel and then slowly turned the wheel bringing both wheels attached to the strings back into their places....but when you try to move the printer mechanism or turn the wheels, it immediately loses its tightness and gets really loose, falling out of the wheels again. Did I screw this thing up or is there a way to get this restrung properly?

Can you pull the keys off the keyboard easily to clean them? I dont want to mess with it before I know...

Thanks a ton for all that...will be checking it out right away! Looks like I need an Adam Floppy drive for that process...dont have one.... I am basically trying to run the diagnostics software on the Adam to see if everything checks out....test it out, make sure things look good before trying to run Data Packs or other software on it...

I thought I read somewhere you could get the Adam to read rom files via an emulator or something? The same way you can attach other systems to a PC or something like that and have it read rom files.... Looking for way to take rom files for the adam and play them on the physical adam....or is this not possible?
