I don't have a manual. How do I set up repeat

If you're looking for a replacement for the IBM Lexmark Wheelwriter 1000, you might consider a typewriter like the Brother M-1000, the Olivetti Studio 45, or the Smith Corona SR8000. These typewriters have similar features and capabilities to the Lexmark 1000, and they're often considered to be good alternatives.

blown fuse or bad power supply

Here's the link for your Lexmark Wheelwriter 1000 Typewriter user manual http://www.national-elec.com/IBM%20&%20Lexmark%20Typewriter%20operating%20instructions/Wheelwriter-1000.pdf

Change the print wheel to a 15 pitch. I believe some of the early WW3's don't type in 15P.
