I might built a little Opto-Isolator circuit for the bass neons instead. I'm going to avoid using a relay for these as I don't really like using a mechanical devices for something that switches so frequently. Since the neon inverter taps it's own power from AC completely separate from the DC circuitry that powers the rest of the cab lights coupling the earth ground from the Bass Neon with the Digital Ground from my PacDrive is probably what blew out my PacDrive last time. As I stated before, there is no relay on Japanese cab, the switching is internal to the Neon Inverter. So for anyone who wants to drive pad lights, and marquee lights and still has the original PAD I/O boards and the original Amp-Box all of those light write ups online that state you need to use relays or Mosfets is complete B/S

Coupled with the ground mod on the PacDrive this works great. I decided to measured the current draw on this circuit and they all drew about 1.3-1.7 milliamp. Specifically a circuit containing an inverting Schmidt trigger (74HC14) and a Mosfet (K2232). The dance pad lights, the control panel lights and the marquee lights are all driven from circuitry in the cab:
So yesterday I modded a Pac Drive to output ground through the + pins and it worked great for driving MOST of the lights.
