My LC won't boot at all. I have already ordered a new PRAM battery but while I wait for it to arrive I want to test my power supply and make sure it's still good too.

Can anyone help me out with the expected voltage on each pin of the power supply connector? Also, are there any dangers to the unit if I try to power it up without being plugged into the motherboard? I know some power supplies need a load connected or they can die when turned on...
