| +5V from a psx pad to P360? |

http://www.gamesx.com/controldata/psxcont/psxcont.htm According to that site, the VCC pin has 5V. Are you saying that I should connect a wire directly to that pin? |

Yes, that VCC pin is what you should tap. That wire, directly, or a trace on the controller board that's directly connected to it. VCC refers to whatever voltage supply is in a circuit that corresponds to logic-high... 5v in this case, but there are circuits where VCC is 3v or even 1v with some new chips I've seen. (so vcc doesn't always mean 5v... just to be clear) What I'm guessing is going on with the voltage drop is that either something is shorted out, or an LED is between vcc and ground with no resistor, or you tapped a pin that's being held at 5v, but isn't directly connected to the VCC power line. (like a logic high coming from a chip). |
