12.2 volts car dies??

[Cody]

Well I did check some of em. Known good grounds: ECU, Valve cover, Manifold. Both alternator wires are güt 'n tight, same with battery and the front engine bay battery tap.

Im watching the battery voltage and it shows 13.2 @ idle (power invertor plugged in for laptop so I would say this is an exceptable number), if I turn the lights on the voltage goes to about 12.8 and the car starts missing. When the rad fan turns on the voltage goes to about 12.2 then the motor just dies imediately. Watching my laptop on the EFI computer shows that it is functioning properly at these voltages, and it is designed to go down to 9v without problems.
