I spent the morning taking apart a 2.3 ghz DC G5 power mac this morning. It made no noises or lights what so ever and the power supply made no click when plugged into the wall. After searching online, I thought I could at least check the fuse. I can see one end of it with the other covered in grey glue and it is not accessible without tearing down the power supply through the goop. Not sure how or if to proceed.
