300zx no power to anything

[the-z-man]

hi guys,
i have a 1991 300zx 2+2 na that ive been trying to find a charging problem in and yesterday i had the car running sitting at idle i had the fuse-able link box by the battery open and i had disconnected the connector that leads from the alternator to the fuse-able link box down by the front headlight and that killed the motor. ive disconnected that before and the motor has never died from that. after that i went to restart the car and there was no electrical power to anything i had no interior lights and the engine would not crank over. the battery was at 11.56 volts. any one have any ideas on what the problem might be?
