Help with Litronics

[crumbum]

I am still battling the right headlight that goes out after about 30 seconds. When I switch the lights off and on again, it immediately goes on and after 30 seconds it goes out.

Relay position F28, as shown in the diagram, is empty on my relay board so I reluctantly had to rule out a relay issue.

Guys I am out of ideas. Any suggestions?

This is what I have done so far (in reverse order):
* checked the ground point and put connector lube on
* opened the headlight connector in the frunk and put connector lube in all holes
* put connector lube on red connector to the low beam bulb
* put connector lube on both connectors behind the headlight
* replaced both bulbs
* replaced the ballast
* replaced the igniter
* replaced the headlight switch
