Is the game working without it hooked up? Is there another type of power supply in the cab. Post some pics of the inside of the cab for us.

Thanks,
Dustyn
 
I took pics of iso transformer:

I took pics of 4 wires not hooked up and the isol transformer (first pic) not hooked up. I turn it on without board and it didn't do anything..then I plugged board in and the monitor sound like it was coming on but no video, but sound came on but is was a med pitch humming noise come out of speaker..without the isol transformer (first pic) hooked up both times..I will also include inside of cabinet too..sorry pics a not that great..it was on my phone..

thanks for all the help..

thanks

Some quick photos. Sorry.. they're a bit blurry. I'm not sure if they'll help you out any. If you need a specific shot, let me know. The 2 blue jumpers go into the connector in the back (sorry i'm not sure where that connector goes, it's been a little while since i've opened up my double dragon).

thanks for the response...I was wondering if you wouldn't mind telling me the wires specifically go to or at least the ones on the bottom..that is how I have it hooked up and I got rid of med pitch humming noise, with no sound or video still, but It sounds like monitor tries to come on but does not..its still not getting all the power..coin mech lights not on and marquee..So, my guess is that its not getting all the power...I have 2 switching power supplys but they are not the one that I have with machine..one is a Hitron HSA-130 +5v 7a, -5v 1a, +12v 1a, and the other one is a Powermaster XII 27-607900 +12v 2a, -5v 1a, +5v 2a, and the on in the machine is +5v 10a, -5v 1a, +12v 1a..would one of these work..

Perhaps these images will help. Sorry, I don't know much about power supplies. The one in my DD is blue...so it could be newer.

The 2 blue wires on the top of the transformer go directly into the molex connector. The Black wire on the bottom connects to bottom of the outlet plug, directly below where i've marked in the photo. The green/white wire goes into the block (sorry, don't know the terminology) as seen in the photo. I'm not sure if that wire connects to the one directly below it or not, but if it does, that black wire connects to the fuse right next to the plug.

no, I wanted to know where the bottom 2 wire are connected too..meaning on the transformer..what what are the voltages where the white wire is connected to transformer and the other wire was is the voltage on that wire going to on transformer...I made a jpeg of what I was talking about


thanks,
Johs

I'll check it out with a voltmeter in a bit.

The wires on the bottom:

The black wire connects to the bottom of the outlet.

The green/white wire connects to the black block as show in the photos i posted.
 
green/white goes to 0 (far left on my transformer)
black goes to 115 (middle)

turns out i don't have my voltmeter with me, so i won't be able to get a real reading right now.

I put wire in the correct place..the screen just flickers and still no sound or video...I was wanting to know what the fuses are suppose to be..are they the same in both slots or are they different and what size fuse are they both...


thanks,
