Just picked up a streetfighter 2 that appears to need caps among other things. My question though is that with the ground and 12 v wires connected to the ps, all seems fine. When I try to connect the 5 v wires it appears to shut down the ps. Does this likely mean I have a short in my 5 v circuit on my jamma board?
 
Are you connecting to the proper 5Volts? Switching power supplies have -5 volts and +5 volts.
 
the main power cord is missing a ground connector. Could that be my grief?
 
did you run this power supply for any lengthy period of time with the +5 disconnected?
