I have an '84 300TD with several electrical issues which I intend to sort out. They might be one issue, but I suspect more than one at play.

1. My horn/reverse lights' fuse blows -- and I can't get the vehicle inspected. I think it is fuse #14.
2. The battery slowly drains over 24 hours.

I have had problem #1 a lot longer than problem #2.
Can anyone direct me to a good wiring diagram for this vehicle? A downloadable full service manual would be even better!
I think I may have a Bently Manual somewhere in storage (across town); I'll have to try to dig that out.

I am going to go out and do a voltage test as I pull fuses, take some notes, and see what that shows up.
Any and all advise is greatly appreciated.

peace and grease,
-Steve
