I know this is a stupid question, but did you do a lot of knob twiddling
yet?  You will get little to no output if the front panel controls are set
wrong.  Check these things first:

Is the cutoff all the way up?  
Resonance all the way down?  
Short Attack, Medium decay, Medium sustain, Medium release?

You mention you're a newbie, so I just wanted to make sure that your
controls aren't set somewhere that you'll get no output.

Next... hook a voltmeter to gate out.  Press a key... gate should jump from
0V to 5V (or 10V... don't know the Fatman really well)

Hook a voltmeter to CV out.  Press keys.... low keys will produce a low
voltage, and the higher you go on the 
keyboard, the higher the voltage will be.

These are the first things I'd check after verifying the powersupply voltages
