waterproofing electrical

I am sick and tired of everytime it rains water pours into my dash and my radio goes crazy. What have some of you done to protect your radio from rain? I very rarely put my top up in the summer and this has been an ongoing problem. I have been through several "marine" radios.

First I am going to follow the steps in the write-ups to track any leaks. Then I was thinking off removing my entire dash and line everything with heavy duty plastic. Basically making a bag to cover everything and leave the bottom open. What do you guys think about this?

I am getting ready to add a cb radio so this problem has been brought to the fore front.

Once again, thanks guys for your help.

The Tuffy is a good solution. A quick and dirty solution is install a plastic sheet above the radio.

My leakage turned out to be that seam in the cowl just in front of the windshield. Sealing that up with waterproof silicone caulk resolved the leaking.

I sealed RC car electronics with platidip spray on. I had to take the electronic parts down to the board level to seal them.

That would be outside the box.


I bet it would be easier to fix the leak. I like the plastic defeltor idea.

The potential problem with sealing electronics is that some components may overheat. There is a reason radios etc are vented.

Cut a vent in the bottom of an old ammo can and mount your electronics in it, add a cooling fan if you need, then bolt that in place of your middle console, lockable and waterproof as long as the gasket is good, plus you can slip the lid off the hinge and lay it under the seat while your using it. You'll have to make some brackets to mount it at whatever angle you want it to sit. Maybe mount two small ones instead of one big one then you have one for electronics and one for storage. I've heard that the 50 cal and 20mm boxes are about the biggest that fit. Not out of the box thinking, just different box thinking.

Usually water gets to the radio from 2 places. The first place is the face of the face of the radio itself. The only fix for this is a marine grade radio. The second place is from the center gauges. Water gets behind the dash from the space between the gauges face and the dash cover. Jeep uses a plastic shelf that is held in place by the gauges that redirects this water forward away from the radio. Which works for the most part. But people usually discard this piece when they take the center of the dash apart or the piece gets brittle and brakes.

I'll bet the OPs OEM water shield is not installed.

I don't have pics. I'll loot on google and post back if I find some.

I have pulled my dash on several times and have pulled the dashes on other YJs several times in the last to replace radios and what not. It is fairly obvious the purpose of the shield when you see it in the dash.

My dash gets rained on all the time and my radio never gets wet.
