Waterproof relay board alternative
I live in the pacific Northwest where it rains a lot. The relay connectors on my MS relay board rusted before our rainy season was 1/2 over. I know some have suggested putting the board inside the vehicle, but I prefer the easy access of having it in the engine compartment. I see a lot of cars with weatherized relay boxes. Can someone suggest an OEM relay box that works well with MS (year/make/model)?
Re: Waterproof relay board alternative
If it has corroded that quickly, it sounds like water is running through it continuously. If it were just humidity, it would be much the same inside the car?

That particular relay board is located in a 1972 Lotus Europa engine bay. It gets a lot of road spray -- a lot!
Re: Waterproof relay board alternative
If you were to use an OEM unit, you'd probably also need the OEM connectors to be weather tight? Might be easier to put yours inside a weather proof box? There are types available with a lid that also seals the cable entries.Homer Jones wrote:That particular relay board is located in a 1972 Lotus Europa engine bay.

Re: Waterproof relay board alternative
Ford uses a constant control relay module that controls fuel pumps, fans, and other things. They generally have 4 or 5, 40 amp relays and a water tight sealed connector. Picking these up with the connector from the junk yard is pretty cheap and replaceable.
Check this out it will show what they look like and give couple numbers. One of the big issues on these were where they were mounted and some have solder joint issues but you can check this before installing it.

honestly I posted these up on one site and got shot down on using them even though Ford has used them for decades with little to no issues UNTIL they have some sort of failure.

Yes - that's what we use on our LSx drop on harnesses now. They're great - sealed, plenty of circuits, and use readily available terminals.DonTZ125 wrote:Cooper-Bussman Power Distribution Modules- IP66, and lots of sockets.
