MSD - Multiple Spark Distaster

I bought an MSD Boost Master off ebay...well it appears to be my first ebay stinker...I spent the day on Saturday wiring it up...on to turn the key and gt a big ball of nothing. So today I went out and ran som tests to see it it was a wiring issue or what...I and getting a (gounding) signal form the mag pickup (hall sensor) this makes it's way too the MSD ...the MSD returns this signal back to the distributor (which is how it controls retarding the timing)...the wire that returns this gound signal give me a big ball of nothing...

I can jump these wires and it fires right up...so I'm assuming this means the box is bad...I'm gonna call MSD tomorrow and verify this.

I did get the mounting board made and installed right now it has the MSD, a couple of relays (for fuel pump and fan), and a spot for the LC-1 wideband O2 sensor. I installed the sendor (you can see the plug in the pic) but didn't instll the rest as it takes some calibrating and I didn't have time to set it up this weekend.
