Not cranking over but will with relay but now no spark

Yes 67 dart has been very helpful..the wire tested ok.im almost ready to run it .. everyone is a great help..I'm learning so much on this car and in general ..it's great
Update!! I fixed all wires that I saw messed up.. started fine ..than stalled.. started again the starter stuck and I pulled battery lead..and starter shut off car kept running so I hooked cabel back up and let it run for a second ,checked battery and was charging at like 18.5 v while reeved up and over 16 when I let it come almost to idle and wires started getting warm so I shut down ..this all happened within couple of minutes..
