68 DART NO CHARGE

Very first thing I'd do is to jumper 12V into the field connector on the alternator, watch a voltmeter connected to battery and watch the factory ammeter. Start, run the engine and see if voltage comes up and if amperage increases.
If so MAKE SURE VR is grounded. If so, now jumper the two VR wires together and repeat--run engine and see if voltage comes up.
Below is simplified diagram. The "Ignition +" comes from ignition switch, the same line that powers ignition---Feeds to VR WHICH MUST B GROUNDED----feeds out the bottom on GREEN and goes to the FIELD terminal on the alternator. So by jumpering power into the alternator FIELD you are causing it to charge full tilt if it is able. By jumpering across the two VR wires you are testing all the wiring in that field circuit.
IF IT DOES NOT charge when jumpered, MOVE YOUR voltmeter to the alternator output stud, and see if the voltage goes high, very high when running. If so, this shows an open in the charge path from the output of the alternator to the battery
