Pelican Case Mod

[SolidusJ]

So I have been doing a lot of thinking and ready to take on a new mod I don't think anyone has done. As the deep water crosser know that water on the fuse box or PCM is bad jo jo. What I plan on doing is try and match the fuse block to a Pelican Case, install it in the case and make it water tight. What worries me the most is the build of heat and how to make the in and out wires water tight. Any thought?

When we did that, what we added was an air line in, and an air line out of the container. The air line out must be smaller than the in one. This creates a positive pressure, situation, that makes it impossible to let water in. We then ran a small 100% duty cycle compressor. This keeps it pressurized and cool at the same time. The compressor had an intake hose that ran up to the top of the snorkel. Otherwise you'll blow compressed water in to the case the first time you hit water. Guess how we discovered that one. I have pics somewhere, but can't find them. Will post them when I do.

I attempted to find a Pelican and other brands to fit the H3 fuse box in. It looks like there will have to be some mods to the area to mount the box. I never found what I wanted. It seemed they were too large when deep enough. I was going to use watertight fittings I have used for propane lines on boats to go into boxes containing the cylinder. The have a rubber gasket and screw together to seal.
I even tried to find a salvage fuse box so I would mess with it and have extra of every relay and fuses all together.
I had to remove the top half of that assembly when I mounted my OEM roof lights to wire it as they outlined in the instructions. You have to be really careful to get it all back together properly.
Let us know what you come up with.
ps, don't blow the air bags!

IIRC, the case is basically sealed except for the lid. Worst case, you'd squeek silicone in and around the wires to stop any infiltration.... So running a seal around the lid would probably get you where you need to be. I'd run a line from the heater box to the fuse box; then a line from the fuse box to the intake (3/8" fuel line or vacuum line) to create airflow....
As for the computer - it's sealed as is its connection .... BCM, I hear there can be problems there so idk

What about a tupperware plastic bowl? They come in all shapes and sizes and the lids seal when snapped on.... And they are cheap so you don't have to feel bad about butchering one up..

I think I found something better Outdoor Distribution Boxes. Does any have the measurements of the guts for the fuse box?

not to mention that the Hummer budget won't take a Pelican-case-budget-hit when your steal a bowl from your wife

Of course, should you get caught - or should your buddies find out that you're using tupperware and there could be problems
