waterproofing electrical ?

Hey guys!
My name is Ben and I have been riding an 85 honda v30 for a couple months. It is a work in progress and my end goal is a bobber. Since I bought the bike I have had to replace both spark boxes to get spark to all cylinders. After I got home from work the other day it rained all night and I came out the next day to ride to the store and found I had another bad spark box.
Swapped front and rear boxes and spark followed. It appears water may have entered the connector or possibly even the box.

So my question is how can I better waterproof these components? Currently all of the electrical components are located under the homemade seat I am responsible for and spark boxes are between the reserve tank the the battery. Because this is a bob in progress they are more or less in the open. I do have a rear fender but there is still a lot of open air.

Here are some pictures to illustrate the general area.

Help!!

Either I'm fucking stupid or I don't get your slang, because I don't know what a spark box is. Are you talking about the coil?

Dielectric grease to seal connections from moisture is all I'm aware of. Never tried making any of my electrical completely waterproof. Wouldn't hurt to cover the bike to keep most of the water off.

Are we talking about the fuse boxes? Because inline fuses would sort that out. The coil should be waterproof so it can't be that.

the cdi box is the unit that controls the coil. there are two on my bike one for each coil. I dont think these are waterproof. I have the bike covered right now, but i hope to be able to ride it in the rain without the worry of breaking down.

Put dialectric grease on all your connections, and put a bead of silicone around all seams on the CDI units.
