Job done.
I changed the starter relay for a new one. This later has the "vertical shape" supposed to be the right model for 1984 trucks.
Hoping this will finally fix my startup problems, chances are good, since I exposed the guts of the old one to the sun and see that one of the pole's contact was really carbonized, beginning melting.
Let's touch wood!

Restored 2019-2022.
Nicknamed «Big Brother 1984», due to its soooo-looong shape & nod to George Orwell's 1984 famous novel.
