'93 240 loosing voltage
 

Battery is about 2 years old and checks good. Alternator is new and chgecks good. New ground cable from alternator. Battery reads 12.85 volts. when sitting. Drops very little over time.

When the car is started, with nothing else on, battery immediately drops about .75 volts and will continue to drop as the car runs. Increasing the throttle speed brings an instantaneous decrease in voltage (.5 volts +/-).

There is definitely continuity between alternator and battery. Car will continue to run with battery removed.

Any suggestions????
