If the battery is down, take it off and get it charged. Use a digital multimeter leads across the battery posts. The generic spec for a fully charged battery is around 12.6 volts, everything turned off. Then, start the vehicle, take a second reading across the battery posts, the second reading should be higher than the first, if the charging system is working. I have to start this way, because I don't know what testing you have done?

With everything turned off, the alternator bat terminal, should show battery voltage. If it doesn't, may be an open circuit between alternator and battery. It's also possible, the alternator feed circuits are faulty?
