drowned split charge relay

Hi

I've got problems with my leisure battery not charging. My bongo came ready converted, with the split charge relay housed in a grey project box with a cut out for the blade fuse holders (3X30amp).

Any way on investigation, I found the project box full of rusty water from our so called summer, one fuse and holder showing some evidence of overheating (molten plastic) but the fuse still intact. I am assuming that the swamping has done the whole assembly no good at all.

So I need some help sourcing the parts, relay rated at 30 amps, is this sufficient for an 85 ah battery?

Also, how do I waterproof the gubbins to prevent a repeat of the problem, or am I better off mounting the components open to the air to prevent the long term bath that has lead to their failure

Many thanks

Ian

Thanks ralph

Is your relay housed in a box, or open to the elements

Ours is in the kitchen unit along with a charger and other electrical gubbins
it's a Mazda unit that as been converted to 240v but in general
electrics are better as far from water as possible.

I'm upgrading to a Willinton heavy duty relay as my (and a friends too) Towsure one is now at the end of it's trimmer screw adjustment and occassionally stops working.

I've also just received a Willinton complete wiring loom/kit to fit to another Bongo later this week - I'll keep youse informed as to its fitment.

Drill a hole in the bottom of the box so it cant fill up with water.
When you re-assemble it use silcon grease on the joints.
Mount the box so its not under dripping water.

If you try too hard to make something water-tight you often end up ensuring that any water that gets in stays in.
