wiring diagram for 82 luv/pup

This is for "general" electrical discussions. Audio, security, remote start, and power accessories should go here, since they don't seem to fit anywhere else. Not for diesel-specific (like glow systems), or gasoline-specific (like ignition systems) topics.

That says 1986. It does not look like the factory manual, but it's easy to read. What is it?
Here's the factory one for the '83 diesel...
Schematic - 1983 Diesel (except California)

I'm not ready to trust Chilton manuals, especially the ones that "cover" multiple years. We've had quite a few complaints about them. Maybe the electrical systems didn't change much over the years.

The 1983 factory manual has one ~11x17 spread just for the Federal spec diesel, and has the same layout for each of the other three variants (Federal gasser, California gasser, California diesel).

The charge relay won't supply power to the fan unless the system is putting out enough power to close the relay. Is it possible your alternator isn't healthy?

Charging voltage is usually somewhere around 13.5v, isn't it? I don't know what it takes to close that relay, but if your system is putting out 13.5v to the relay, it should close and you should have power coming out.
