Id get it going first dave.  Here are  a few threads to help you on your journey to getting it going.  
First Check that the fuses are the correct values and not blown
Check each coil with a Multi meter to check they are not Dead?  (Ask if not sure)
Visually check for any badly bent relay switches or anything that looks out of place
Manually put credits on the game in the backbox
Turn it on and push start (Be ready to pull the plug if something locks on)

Then if the game scores dont reset to zero check this link on how to fix the score reels  http://aussiepinball.com/index.php?topic=1710.0

If the scores all reset to zero and the game score motor is still running (INSIDE THE BOTTOM OF THE CABINET)
 Check your stepper units as in this thread      http://aussiepinball.com/index.php?topic=1707.0

And keep us posted and ask as many questions until your ready to have a go at it
