Need help with sealed beam headlights

So since I bought my 96 xtra cab, I've had issues with my sealed bead headlights. I've gone between having only high beams, no lights at all, or even half-power really dim headlights. I have tried switching between the sealed beams and conversion glass H4's. Same problems.
I've spent countless hours over the past year trying to figure it out, but just cannot. So i figured i might see if anyone here can help me.

My current wiring setup: only high beams function, low beams do not
Passenger side Switch position Driver side
Red/white- 12.39v Low Red/blue- 12.44v
Red/yellow- 0v Low Red/yellow- 0v
Red/green- 0.02v Low Red/green- 0.09v

Red/white- 12.39v High Red/blue- 12.44v
Red/yellow- 0.03v High Red/yellow- 0.09v
Red/green- 0.03v High Red/green- 0.09v

If someone could send me a picture of their 96-97 headlight wiring, that would be great.(power output to each wire in both switch positions would be even better)
BUT, i think my issue may be in the actual wiring of the truck. I feel like having only one wire in the harness that gets power is wrong - I should have two hot wires with the high beams switched on. And YES: I've done extensive searches already, and i have checked and replaced all fuses and relays, and bulbs are intact and fully functional.


Please give me your opinions on what you think may be the issue.

 

Well, if you've changed switches on the column & traced, are you original owner ? has truck ever been in flood ?

 

I am not the original owner, bought used from a guy in Arkansas. Not sure if it's been in a flood. And actually, have not replaced the column switch, but I know through trial and error that the switch works fine. Have NOT traced wires from switch to headlights, only have checked harness from headlights to firewall- all good.
