I have a DM4400m, and much of the info might be beneficial, but I'd try to find the 4500 version first. The DM4500 manual will have the wiring schematic and the parts listing, which can help, but Dyna went bust years ago so it isn't as though you can order parts from them.
Parameter wise, most of this is written to EEPROM. SO DO NOT MESS WITH THE MACHINE UNTIL YOU HAVE TAKE A PARAMETER DUMP!!!!! You very well may have everything sitting there right now and you just need to reinitialize the RAM. Let's put it this way.... Even if the machine doesn't have the parameters anymore, there is no harm in downloading the params to a computer before you start wiping things out!
