Classic/Antique Car Repair: 1969 chevrolet wiring, chevrolet c10, ground wires

Question
I have a 1969 chevrolet c10 that i recently bought as a project truck, there are only two current electrical problems i am concerned about, my dome light does not work, and it would be quite helpful if it did, and my reverse lights do not work. I was unable to find a diagram of the courtesy light circuit for this truck for free so that i could fix the dome light, where could i find a free diagram?

Hi wel have you looked at the fuses to see if they are blown , or did you also check the bulbs.  get a test lamp and check for juice at each socket when the power is on.
you can try the library for tech books.
HEA  did you tell me that you checked the fuses NO. also Check all of the ground wires also the body grounds if there are bad grounds you will get little or nothing. and did you check the bulbs and fuses you did not say so. Happy New Year
