This might be a silly newbie question
When I measure voltage on a HDD power cord, I get a reading of around 5.2 volts with the Jamma NOT connected to the PCB.
as soon as I plug the Jamma into the PCB, the fan on the power supply quiets down, and the voltage drops to somewhere in the 2V range.
Am I missing something silly? is this normal?
The game will not load or boot anything up and that is the only thing weird I have found.
The power supply and monitor work with a different game, so I am down to either the PCB, the HDD, or my lack of knowledge.
any help would be greatly appreciated.
Thanks in advance!
