I have ea81 Brat. I just swapped out the dizzy cap because the old one was letting moisture get in.   Any tricks for keeping water out.  I'm thinking of just smearing dialectic grease around the base of the cap, and around the wire boots.  Any other ideas?    Also what is the difference between dialectic grease, and vasoline? Can I just use vasoline?

Its been along time since i messed with a ea81 but on the ea82 the disy and the cap both have vents to let condensation out on mine i modified the vents and inserted nipples

In to the holes and ran a hose up under the dash then siliconed everything cap and wires in place when i get new wires ill run them inside of garden hose filled with silicone aswell but thats more for running in deep water than just puddle jumping my dissy stays nice and dry i also run a aftermarket ignition that im sure would help if alittle moisture did get under the cap on yours i would start by checking the vents if it has any and make sure everything is clean dielectric grease wont hert anything and will stop water from splashing up and shorting out your dissy but i dought it will stop the moisture under the cap problem u might also have week spark or are in need of a tune up

Just keep some napkins in the glove box for when you get it wet.  Water proof it with whatever magic grease you want, condensation still gets inside.  Then your magic grease just makes it harder to open up to soak up the water inside.
