Thank you, thank you.
I don't know why the OP's fuse blew, but I think mine blew because when I purchased the camera, it had suffered from some battery leakage issues and I cleaned a lot of battery acid out of the body. I theorize that this either induced a larger power drain due to resistance or began to corrode the exposed wiring on the inside of the camera.
While the camera worked for about 6 months, one day I accidentally knocked it over on a table; Not hard, but a solid bump. The very next day, after auto rewinding the roll I shot, the camera refused to load the next roll and flashed the dreaded "E" constantly. I'll bet the voltage strain on the (assumed) corroded wires of the fuse caused it to part.
Anyway, I will find out.
