On my non running 74 2.0, the alternator light is on all the time. If I turn on the key it goes out. Any ideas?

Had similar issue and the voltage regulator had went bad. You could quickly unplug VR from fuse box in engine compartment as cheap and simple test. otherwise ground issue could be in play
