I can send you another one, but it might be quicker for you to stick in another one. Here are some of the specs for it:

HCPL-817-000E Avago Technologies Transistor Output Optocouplers

So I guess something that's similar to that.

These are very good:
FOD817D300W Fairchild Semiconductor Transistor Output Optocouplers

Do you want me to mail you one of each, straight from Mouser?

If you short from Pin 4 to Pin 3 on U9 (maybe with an alligator clip or something), does the contactor close? Be careful not to do this before the precharge has happened. I would verify that the capacitors are full first. If the contactor closes, then Q1 is good.
