There should be 12 volts or close to it at the alternator b+ terminal. Possibly a wiring problem,fried fusible link wire or a blown fuse depending on vehicle make and model. Check for blown fuses or check at the starter solenoid for fried fusible link wiring. Some makes ,the PCM computer regulates the voltage...possible PCM problem,again depending on vehicle make..... You didnt specify what kind of vehicle this is...Year,make,model,engine size.... Doc J
