Do they have a main fuse?? If everythings dead hopefully it's something simple. Did you put a meter over the battery? If it was dead/dropped a cell, or flat you would still expect a slight glow on the dash lights ???? I know on all early bikes there was a fuse link off the +ve off the battery(I just popped this today f*&^ing with lights on the six)
I don't want a pickle . . .
