1975 Dart Sport - Alternator Issue?

No run a jumper from the battery + terminal to the field terminal of the alternator after you have disconnected the green wire. It should put out "full." If it does not the alternator is weak or non functional. Watch the battery with a voltmeter and slowly bring up RPM. Don't allow it above 16V or so. Turn on all loads, lights, heater, all you have, bring up RPM and see if it will come up above at least 13 or better
