Electrical problem
1999 Ford Taurus 6 cyl 100000 miles

Replaced battery, alternator, starter, battery saver relay, and module on alternator (double checked all at auto zone). Car will not hold charge or run unless booster box is attached to battery, as soon as I take it off it dies, immediatly. Any ideas please.
