clocks out, strip the back, remove circuit board, polish screen. checked seal, seemed ok,
i used low strength lockthread to wet the seal and be sticky, thin line all round it.
tightened screws a squeak tighter than they came off. then a line of black tape round the joint(ya cant see it)
the power plug on back is 'vented' as in ya can see past it to inside of board. it needs double checked that the boot is pushed right up in.
iv washed the bike today after 70+ mls in the rain on sunday, and its still dry.
fingers crossed.
