Can someone help? I need to drive my dart tomorrow

Nice. You're making progress. :)
Lets see where those extra wires come from.

Smoking could have been dirt or damage, or just burning off a bit manufacturing finish because this is the first time it (the electromagnet and resistors) have really heated up. Look for signs of excess heat to get an idea of whether this was normal breaking in smoke or high resistance or current issue.

Depending on the alternator and idle speed, 12-13 Volts may be close to normal. The tests for VR operations and alternator outputs are usually done around 1250 rpm. There's a second VR test done at 2000 rpm if I recall correctly. IF the voltage does not come up to the low spec at 1250 rpm, then maybe the spring tension needs adjustment. Edit, For the lower rpm test (1250) put some load on it (headlights or heater fan), for the higher rpm, no load. Also check the points for signs of burning and that they are smooth and flat, and check the gap.
