12V dc LED's not flashing when 12ac transformer used

[U.S.AutoService]

     I worked a lot today changing all the LED's in a Slot Topper today, I just installed 38 12v dc red/blue flashing LED's in the topper.
I was testing it while I was doing it with a car battery and some jumper wires.   I got them all working and it looked cool.
All flashing red then blue and then back to red... So I put it in the topper and hooked it up to the internal transformer...
... and all I get now is all red LED's and they are always on.... not flashing....  is there someting I can do to fix it ?
It works with the 12v car battery but not the 12v transformer....  

 I'm thinking a resistor  ?  or maybe a flux capacitor


   Thanks

sure there is a good technical explanation for it but why don't you just pick up a 12VDC transformer

LEDs are diodes.... but flashing LEDs are not. They are IC chips and diodes.

Try hooking them up to DC again. If they still light all the time and do not blink then you probably fried the chip by putting AC on them.

 I tried them again, and they work fine.  is there a place in the slot that I can access a 12v dc to power them up ? 
I have them on top of s2000's.

If you have the fan in the top box that is 12v-13v
The power distribution board has 12-13VDC use the red and black/red wires Red is positive and black/red is negative.
If you do not have the power distribution board there is a 9 pin square molex connector with heavy orange, black/orange, red and black/red and 5 green wiires with a color stripe use the red and black/red for 13V
It is a netplex connector thats why it has the 5 green wires as well.

Whatever you do STAY AWAY from the Orange and Black/Orange wires 25V

No fan.... but I do have a black box plugged into the bottom of the slot machine 120V ac plug, that has a smaller cable running to the
top( i think 6 or 8 pin) that is not being used.
  I think it is for the display for the players info screen.  I have a few of those around, are they any use ?

I would only use that connector if it 12VDC.
 
Look at the back of the top box rear left bottom side you should have 5-6 connectors back there, if you look to the left of Reel 1 you will se the wires going to the molex connectors there.

one of the connectors is for the speakers.
one is the SENET connector
one is NetPlex connector (9 pin square 3x3) has the 4 wires that are 16-18 gauge  (Orange, Black/orange, Red, and Black/red) plus 5 green wires with stripe on them.
2 or 3 others I have forgotten exactly what they are.


The Netplex is the one that has 13VDC for sure.

   I will look as soon as I can, they are at my work.  I will try tomorrow.  will a dvom be ok to check voltage ?


              Thanks !!!!!!!!!!

Yes a good Multimeter will do.

 Wow, you hit the nail on the head !  THANKS !!      I went in and found the wires right where you said they would be. The topper is working.
Hope someone else can read this and get the same results, way to go.
