No lights issue

[Slooptin]

Finished putting my truck back together and it runs great, but I don’t have any lights (interior or exterior). Went through the whole troubleshooting process and found that my wires are good (continuity tests passed), but I’m still not getting power to the headlamp switch. I think I narrowed it down to a faulty “s” terminal on the starter since I can jump the two s terminal wires to the junction block on the firewall and I kinda get headlights (see pic below). Just wanting a sanity check that this is the issue. I also drew up a bare bones wiring diagram from what I’ve found

Check your fuses.

You have the wires on the starter wrong. The fusible links and the battery cable go on the large post,only the solenoid exciter goes on the s terminal

Check your fuses.

Fuses are all good

For everyone's benefit and to save troubleshooting time,a fuse will not take out headlights on a factory wired Squarebody truck. They get power from an under hood fusible link at the starter and by the headlight switch itself which has an internal circuit breaker.Dash and taillights are fused.

One of the red wires (with fusible link) at the starter runs to the bulkhead. At the bulkhead (inside cab) it splits into two red wires- one runs to fuse box for tail lamps & ctsy etc. The other runs directly to headlight switch. If "NO" lights are working- I would be looking at the fusible link and making sure it is connected correctly at starter.

He's not hooked up at the starter correctly. He drew us a diaghram on post 1. Take a look, not bagging on you. But if you look at his diaghram and confirm what I said,maybe others and the O.P. will know the problem is found before we get 97 WAGs to confuse the issue.

So fusible links are good I’m assuming since continuity tests were good. I definitely had it wired wrong. Thanks Ricko1966!
