Coin door lights get 2 volts When directly connected to powersupply
I have a switching power supply and a jamma harness in my machine. I have two 12 volt coin lights in the door. I have a 6 port connector for the power coming from the power supply:
2x 12 from a single 12 volt on the PS
2x Ground from two grounds
1x 5 volt
1x -5 volt
The lights use one of the 12 volts and a ground, everything else uses the other ground(buttons).
When nothing is plugged into the JAMMA and the coin door lights are not plugged in, both ends read 12 volts. When I plug in the coin door lights, it immediately drops to 2 volts, and the lights are dim.
If I plug a gameboard into the JAMMA port, then the coin doors get 12 volts, and the gameboard gets 12 volts.
Anyone have an idea how I have my wiring incorrect?
Let me know if I need to re-phrase my wording.
Thanks!
