75 F-150: zero power
guys,
RE: 75 F-150 360 V8
I was fixing my intemittent plug on the key / ignition and the larger yellow wire popped out & crossed with some metal.
Smoke was coming up at the battery / solenoid. Now I have no power what so ever.
- no lights
- nothing on the key
- battery is fine
I don't know where to start. I will go get the Alt & Sol checked, but why no power anywhere?

Look in the black wrapped wires that hooks up to the starter relay.
Follow it to at least the firewall.
Inside this wrapping you will probably find burnt fusible link wire.
It is supposed to do this > to protect the truck from catching fire.

yes, I seem to have power to the coil. Turning over, just won't fire / spark.
EDIT:
Is the module testable? I also see a module on the rad wall, should I junkyard replace these modules tommorrow?

Yes you can have your module tested at any good auto parts store.
There is a test in a manual but it is a long-winded type test.
By a Motorcraft unit not a cheaper thing. Look for the little 1/4"shoes on the bottom of it before you buy it..
It is best to have a spare module with you any way.

I had the illustration of the starting system for you to trouble-shoot different spots.
I think you are going to have to be slow & thorough in figuring out the problem is.
Write up a check list as you test circuitx.
Is there Spark at:
plugs,Plug wires,Distributor cap,rotor,module inside cap,wiring to module from distributor
Did you Get the module tested at parts store?
Ignition switch: check key on powered circuits (especially the run circuit)This is where I think the problem is,possibly the harness from battery.
