Question about Chevrolet C1500
The no headlight at any position is significant. it indicates that the entire electrical system is not getting B+12. Since there would only be two terminals on the battery and you have checked/confirmed that the negative is body grounded, it would only be the positive terminal. The positive terminal has two (2) connections; 1 would be very big and would go to the starter, another smaller would be the systems B+12. Often this 2nd B+12 wire passes through a fusible link which looks like a wire but is really a big fuse. It would likewise pass through a connector. based on this, you may want to check this fusible link and/or its connector. When in doubt, you can always temporarily replace this with ordinary automotive electrical wire to verify. Should this checkout OK, the next step would be to look for a master/main relay or a master fuse/circuit breaker.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
