Apple Iie Doesn T Power Up When Floppy Disk Drive Is Connected Apple Iie

Chosen Solution

Without floppy disk drive connected,computer powers up,no beep,and it seems ok, I did a system test,on the screen appeared system ok.I connected the floppy drive while machine was on and the floppy started spinning,reads the disk. When floppy disk drive is connected to the controller card and I try to power up the system,nothing happens,not even power up light is on.Thank you in advance!
