I have looked thru all the manuals I can find on the Z3805A and I cannot
find the wiring diagram for the 24 volt XLR connector. Can anybody
point me to a reference? Thanks.

Hi

There is a description of what’s what here:

https://www.prc68.com/I/Z3805A.html

You also can pop off the top lid and see what goes where internally.

Brett,
Look at Brooke Clatk's page at https://www.prc68.com/I/Z3805A.html#Operation; there, you'll find a good deal of info on the Z3805A. The power connector isn't drawn out graphically, but immediately after the Operation heading, subheading DC Power, he describes the power connections.

(Positive on left looking at rear panel, negative on right and chassis ground at the bottom).

Hope that helps,
DaveM

Attached is a photo of the XLR power connector. It agrees with Brooke's
annotated photo:

That said, I learned the hard way it's good to look inside at the power
pins, especially if the instrument came from eBay / garage sale / ham
fest. You never know for sure what mods the previous owner did or why.
Also, telecom gear doesn't necessarily assume frame ground is negative.
