Hi All

Advice please. What is the best way to make a 12 volt waterproof joint under the motorhome running along the Alko chassis - for 4 x LEDS - very low current useage?

Have considered thus far:

Solder and shrink wrap. Scotchlock. Waterproof junction block.

Any thoughts please.

Thanks

Solder and shrink tube then self amalagamating tape

Scotch locks a not a good idea for permanent joints, ok for emergency in my opinion:thumb:

The correct method is a waterproof junction box as used on trailers etc but then you knew that didnt you:Doh:::bigsmile:::bigsmile:

Hi, I was going to say :winky: If you want a Dry Joint :winky: solder can make a good one.:Doh: But I would use a waterproof junction box, after having lorries,:Doh: you will find it a lot easier to find a fault (if you have one ) with one fitted. :thumb: Bob.

We use IP65 rated Stainless Steel motors. The conections are made by soldering the wires and heat shrink tubing that has a coating on the inside that melts with a heat gun. The terminal box has no seal just a lid. these are 400v three phase and being washed down countless times a day, never had a problem. Bought some of the tubing from fleabay.

on and off for the whole of my existance
another option!?!?!

I have for many years used insulated female and normal male spade connectors, but put the wire into vaseline before crimping and then the male spade in vaseline before connecting the two together.

I have used this on landrovers/trialers which are regulaly submerged.

The heat shrink i agree is good, but when a slight crack/split accures the water gets in but cannot get out, causing problems.

Happy wiring
