Problem solved. And, as usual, it's my fault. Or maybe my wife's. When trying Cobber's suggestion to work locks manually I found that the passenger door was not fully closed, although it looked shut. After closing, everything worked as MG intended. So fuse back in, lights, clock and radio back up, all's right in the world.
Philip, my apologies for speculating that pscan might somehow have been involved in my problem. Correlation is not causation. And thanks to those who took time to try to solve my problem.

P.S. My background is in explosives, EOD and demolition, so I have terrible trouble avoiding the spelling 'fuze'. Think I made it this time.
