Would a bad alternator cause the truck to stop running?
Yes, the alternator provides electrical energy to keep the battery charged. If the alternator isn't functioning, the battery will discharge and there will be insufficient electrical energy to operate the ignition and other electrical components. Understand that a battery is only an electrical STORAGE device. Electrical energy is produced by the alternator. The function of the battery is to provide electrical energy for NEXT time you want to start the engine. Once the engine is started, the alternator must take care of all electrical requirements of the vehicle as well as for providing enough additional electrical energy to replace electrical energy to the battery that was last used when the engine was started.

you have a dead short somewhere in electrical system. have the alternator checked even tho it is new.these have been known to b bad from the getgo. also have the starter motor taken out and checked by a good automotive electrician.these can have a short but still work check the voltage regulator.these are either built into alternator or are connected remotely the alternator and battery complete the electrical circuit, so if one is bad it will stop the vehicle when battery charge is gone Rocky_B - See my entry here for more things you might want to check: http://wiki.answers.com/Q/What_could_be_wrong_if_the_battery_light_stays_on_and_the_battery_still_runs_down_on_a_1996_windstar_after_installing_a_new_battery_and_alternator
