Classic/Antique Car Repair: 1969 camaro coupe

Question
Sir:
I have a 1969 camaro with a 350 engine, 350 turbo transmission, 3.73 posi rear. The car is stock except with the addition of headers,4bbl ,and mild cam. The problem is that last summer my son who is a mechanic took the engine out and put core plugs. front and rear main seals, oil pan gasket and front trans mission seal, which was leaking badly. The problem is that when he put the engine back in it won't run now. I ran fine before. So in the meantime he got mad at me for something and left me high and dry with a car that doesn't run. This is the first time the engine was ever out of the car till now. I am the second owner and I have had it since 1980. for some reason he cut the wires that go to the coil and distributer, oil sending unit, and temp sending unit. the only wire that I cant figure out is the color of the wire to the positive side of the coil. It looks like in wiring diagrams that, that wire should be yellow with a stripe. Witch I cannot find. Plus is the coil wire supposed to be constantly hot with the ignition on? And there's seems to be a black wire covered in white fabric that has a loop in it that I have no idea where it goes. Plus how do you test a coil to see if it is any good. I know its a lot to ask but hopefully you can help me out a little
Thank you so much for your time and expirtese.

Answer
Lets see if I can help out a bit. There are two wires that run to the + side of the coil. One should be hot when the ignition is turned on. That one connects to the ignition switch hot terminal and runs through a ballast resistor.the other one should be hot when the ignition switch is turned to start side and is the bypass so that the resistor is cut out of the circuit when cranking. The there is only one wire connected to the - side of the coil, and that runs to the distributor  points. You should be able to match up the sender wires. The coil can be bench tested using a condenser (like the one connected to the points in the distributor), spark plug, and some jumper wires.Connect the condesor to the - side of the coil. Run a jumper from the case of the condenser to ground. Run a second jumper from the - of the coil to ground. Rig a spark plug from the center terminal of the coil to the center terminal of the plug and the case (where the treads are ) to ground. The connect a jumper from the + terminal of the coil and slash it to battery +. Each time you flash the wire the plug should fire.
