don't forget, if fiddling, disconnect the rear battery too (before shorting stuff out)

pictures on ebay do look like it might split apart around this very relay (and that might mean you can get at it) - BUT as so many secondhand spares out there - I guess if this is playing up / dead - a whole unit would be a sensible thing to have to hand - it, after all is not playing with low Ampage
