So I'm writing this for my friend but he has a 1978 F-150 with a 1969 390 in it. He recently had a problem where his starter got stuck and it lit the wires connected to the solenoid up in flames. Well anyways we replaced all the wires that were attached to the solenoid and replaced the solenoid and the starter also. But after wiring it up it has no power whatsoever. The battery is also brand new and the fuse links are fine. Any idea of what is causing this?

 

More likely than not, he attached a set of wires to the wrong terminal of the relay.

Other than that, you're going to need a test light or multimeter to figure it out.

 

Yes Ford used the large terminal on the solenoid going to the battery as a point to pick up power for the whole truck. If you do not have the proper wire on that terminal, no power. Also check for rubber looking things in the wires, these are fusible links. Pull on them, if they are burnt they will be stretchy. If you have cut all the fusible links out, you really should replace them.
