I have no power at all, I put jumper cables on it, and I still have nothing, no lights, nada. I took the battery off and put it on another truck it started rite up I even had it tested, it has a new starter, solenoid, battery cable. It has push start so there is no ignition. I tapped two screw drivers from the solenoid and it sparked so its got juice. Its a 302 from a 73 grand torino I believe that's the name. There's no blown fuses, doesn't seem to have any cracked ground, nothing, it use to make one loud click everytime I cranked it and it wouldn't start so I changed the solenoid and now there's nothing I put two different solenoids on to see if I had a bad one. Any ideas?

 

Did you replace the solenoid yourself? Go out and take a look at the starter solenoid. Look at the post that is facing the battery, the post that the positive cable bolts too. There should also be a red? wire going to this post. If there is not, you need to find it. This wire controls all power to your truck. It's very easy to overtighten the positive battery cable onto this post and damage the 31 year old ring terminal, allowing the wire to fall off. I had this happen to me before.

 

X2. I've had it happen also.

 

Yes, there should be 1-4 wires that attach to the battery side of the solenoid. These wires power everything on the truck. The number of wires varies over the years, as well as factory installed options.
My 1980 F150 has 1 wire (black/orange). That wire powers the alt, and between the solenoid and alt it has a factory splice that feeds everything else from a large yellow wire.
