Still nothing when key turns to start on 1995 Honda Accord

to summarize a previous post- gave a jump to someone, got home, shut off the car, 20 min later everything worked until the key got to the start position--two clicks from under the hood-nearly simultaneously-and all power quits, no lights, no power until I remove and reattach the battery cables. Have charged the battery, removed and checked the starter, removed a 5 pin relay from behind the control unit under hood(think its for the wipers-two adjacent pins have continuity, thought that was a fault) disconnected the altenator and tried to start it only with the same results. Show continuity from the control unit hot leads to the engine block. AND with only the positive cable attached I put multi tester leads on Neg terminal and the engine block and read 12+ volts. WTF? HELP!!!!

maybe you blew a fusible link
ck pwr fuses under hood. poss one is blown. that happens at times if you jump start
All fuses are good. took each out and checked for continuity. Battery terminals are ok. removed relays under the dash and still got a voltage reading from negative battery terminal to engine block with only the positive battery terminal connected. That's not supposed to happen, right?
Maybe check to see if the battery is hooked up correctly, if not OEM battery , maybe posts are reversed. AND fix blown fuses.
