[Swan] 508 problem

[yash at aol.com]

   I received the 508 vfo today,was a rat, now looking pretty good. I plugged the vfo into the 500cx and nothing but pilot lights worked , no audio ,just white noise. I took apart the 9 pin plug and found several wires broken and several grounds going no where. I looked in the compendium found the 508 and the 500cx should play together with no changes made to the vfo or the rig. I downloaded the schematic of the 508 but the quality is so poor its hard to make out any numbers to double check the plug. and relay wiring. Does anyone have a clean schematic of the 508 they could send. I just dont want to make any mistakes with the plug wiring with 200+ volts getting put in the wrong place.
thanks for any help
