's'always been like this, even pre-relays, I have old fashioned bullet fuses, they're all ok.
relays are wired to one side of the original lamp circuit, with one relay for hi-beam running both lamps and one for mains. Lamps are driven from a new secondary fuse box.
I'll bear in mind the fact that I may have made the problem harder to fix now that I've effectively cut one of the switched circuits out. Cheers for the info.
Skell, don't drive any of yours out of sussex, they'll have to go into quarantine
