Test result after repeatedly measuring, truck side to coil-red wire.
Red/light blue wire: 0.2V in Start(hesitating continuity-ohm meter), 12V in Run
White/light blue wire: 0V in start(continuity-ohm meter), 0V in Run(continuity-ohm meter)
Will get test result of ignition module tomorrow.

Alright, here is one of your problems.
White/light blue wire: 0V in start(continuity-ohm meter), 0V in Run(continuity-ohm meter)
You now need to go in the cab and confirm that you have power coming out of the ignition switch at the Red/Light Green wire with the truck in run.
If you do have power there at the red/light green wire at the ignition switch connector. You then need to check the white/Lt.Blue wire, all the way from the DS-II connector, back into the cab, to where it splices into the Red/Light Green wire between the ignition switch and the resistor. This may involve removing the harness wrapping.
If you do not have power at the Red/Light green wire at the ignition switch connector, ignition switch in run. You need a new ignition switch, or the old one is severly out of adjustment on the column.

Back again.
I left the ignition module at an automotive electrician, for testing., called him today and got the answer that the module is dead.
When byuing a new one, I can get Motorcraft 160 dollars and Standard Motor 80 dollars, here in Sweden, is there a big difference in quality and performance between these two?
I checked the red/light green wire at the ignition switch and there is 12V. Where this wire connects to the ignition switch, the white/light blue wire does too !? This at point 4 for ignition switch (picture) in Haynes wire diagram 81-83 F-series.
Have not followed the red/light green wire to where it splices in to the white/light green wire.
At the truck side connector by the ignition module there is 12V between white/light blue wire and distributer base, in run.
When following the + coil red wire back to connector by ignition switch, it changes color to brown/purple and after some inches further back( in engine room) splits up to brown/purple-pink/white(or tan). This pink/white wire is thicker and softer than the brown/purple and I can't find it in the wiring diagram. Can this be the ballast resistor?
