Check the connectors at both ends of the cable and make sure they are tight. Also check the insulation along the entire length of the cable to make sure that it's not shorting to ground. Do this for the ground cable as well. If that all checks out, and the cable is old (I see it's an F-100, after all), you may do well to replace it, as it may have corrosion inside the insulation which can cause all kinds of problems.

1999 mitsubishi mirage where to check does not have power of 5 volts in the throttle position sensor connector and check the fuses I did not find bad

Loss of 5-volt reference can be caused by an open in the wire (check the continuity of the wire from computer to TPS) OR a short in the harness or another sensor that uses the same reference wire. White smoke off the engine or out the tailpipe? Loss of 5-volts would never cause white smoke out the tailpipe

2004 chevrolet classic 2.2l won't start, maybe have a short circuit on positive wire,circuit, because make nothing no radio no lights inside and outside I check battery is ok fuses is ok, looks st

If you have positive battery cable that is shorted, fix it. A dead short to ground should smoke it or get very hot. Check ground, also.
Use a test lite, ignition bat fuse 1 and 2, underhood fuse block, Should be hot all the time. Voltage and ground, both, are important.

Replaced starter except the wiring...i connected the ignition first and positive wire second. then connected the clip(black clip) made sure ignition went on first, positive wire second. Neither touching...

first you are going ot have ot check the wiring for any potential damage, this will entail you doing a continuity test and voltage test. you need to verify that you did not damage the wires in a way that will prevent them from delivering the charge to the starter. You will need to test the battery and make sure you did not damage any of the cells in the battery a simple voltage test with a multimeter will verify it is operating ( you will need between 11.8 and 12.6 volts) after you have made sure everything is in operating condition. Just as a side note you will want to be sure that all the fuses and relays are not damaged from the smoke out.
Once you have made sure all the wires and components are in good shape you will be able to repair the starter situation. When you try to reinstall the starter you will need to make sure that you are connecting the starter 'hot' (the battery positive) in the correct place on the starter, i imagine that you placed the battery hot on the wrong terminal of the starter and let the smoke out that way.

Im having electrical problems its smoking from the fuse box

Okay I need a bit more clarification. Is it smoking from the fuse box in the engine compartment or inside the car? Does it start smoking when the key is turned to the on position but the car isn't running? Or does it smoke only when the car is running? Check to make sure nothing has gotten spilled on or into it. Does the fuse box look charred? How do the wires look?

Replaced starter when battery was connected it started sparking and smoking.

Sounds like he may have pinched a wire or hooked it up backwards or has the power wire touching the starter housing.

Your car has a very poor ground wire. If you replace the ground wire that should solve it.Good luck
