I have a Final Fight PCB, want to hook up coin door lamps (currently stripped, non existent).
The manual says hook up to the -5v on the power supply. However this raises a few questions for me.
1) What type of bulbs can I hook up off that line? Is it as obvious as 5v? I thought there were different kinds of bulb voltages.
2) Do I have to run 2 separate hot wires to the -5v line, or can I wire them in series like speakers without dimming bulbs or ruining something?
3) Do I need to install an inline fuse, if yes what amp? Is the fuse going to be the same if wired in series?
4) What's the difference between hooking up the lamps to the +5v spot as opposed to the -5v spot? I see many debates over this on klov between many great minds. Who's right??
5) And lastly the -5v or +5v means that amt of voltage always readily available no matter how many things or what's drawing a load from it?
