I have an NBA jam that plays blind. When I opened up the cabinet it was a rats nest of wires and spliced connections of which the power wires to be monitor chassis fell out of the power molex, touched and blew the original power supplies fuse..in other words it's a mess.
I am going to redo all the power distribution BUT my question is why would someone use 2 power supplies?
In this case a new switching one goes to the pcb and then it's spliced into the original one which is a psu+iso that powers the monitor, speakers/amp, marquee light, coin door. In other words it's like a psu going to a psu..I thought maybe the original psu didn't work but it's where all the power comes in as the fuse blew and the cabinet is completely dead.
Or maybe it was just being used as a distribution block.
