Seatbelt light ALWAYS on

[Scott76]

So I'm rebuilding/customizing my new to me 79 C10. One thing I'm chasing is the seatbelt light stays on all the time. When I say all the time, I mean all the time. Even with the key out/engine off. The interior is gutted so the seatbelt retractors aren't there, so I get that the light is on, but even with the key out? The only thing that makes it go out is pulling the neg battery cable lol.

For 79, the seatbelt light is controlled by a "seat belt warning buzzer & timer". But that receives power via the pink circuit #39 wire that is supposed to be switched on & off via the ignition. Start your troubleshooting by using a test light or voltmeter to see if power to the "gauges" fuse switches off as it should.

Great, that will give me a good start. Thanks.
