Engine kill relay

Yahoo Message Number: 10972
OK, so I thought I had finished all of the jobs for my next trip (oiled, lubed, brakes serviced, even got my Howard Power Steering working again!) and then in Destinations I read about a relay in my engine kill circuit that I should be worried about.
Is this something I should replace (I just turned 76,000 miles)? Does anyone have a part number for NAPA or should I just get it from CC? I can see it and it looks fine to me, but the so did the bad relay on my Howard system so what do I know.

Thanks!

Mine is a Bosch P/N 0 332 204 150. It is a SPDT and It looks like it is connected to the NC terminals....which would make sense. At this web site, they show basically the same thing, probably a newer model. For $1.99, it is worth having one in the tool box.

Any decent parts store should carry this or an "or equal". It's just a 30A, 12V, SPDT relay.

Mine is right next to the engine kill button. Open up the rear engine access door and it should be right there on the right side.

I believe the correct part number is 0 332 209 150..... note the "9" in place of "4". The numbers look similar.

By the way, in my 2004 Allure #31031 which has electrically powered slide outs, these relays (four of them) control the drive motors for both slides. In my coach, they are mounted on a board located in the rearmost passenger side compartment. The board was mounted "upside down" when compared to the electrical drawings.... thus confusing correct identification of specific relays and terminal strip connections. ADDITIONALLY.... this mounting caused all four relays to be mounted with their terminals facing upwards. Within my first 2000 miles, I had three of these relays fail, one of them was a second replacement.

I finally realized that the nearby compartment drain hole was apparently letting water spray in and fall on the top terminals.
These relays are not sealed. I noticed corrosion between the terminals.

It is my conjecture that water sat on top of the terminals, leaked down inside, and corroded or otherwise damaged the internal contacts, coil or other parts.

I've turned the board 180 degrees, placing the relay terminals facing downward such that if they get wet by spray, the water drips off.
10,000 miles later I've had no additional problem.

An alternative would be to fit a drain hose to the hole in the compartment base, making it less likely that spray would enter the compartment.... but I had no proper hose handy. Additionally, I believe some spray (probably most of it) comes in through the engine intake grill on the compartment door.... thus the need for the drain.

Other solutions might include: 1) coat the terminal side surfaces with silicon sealant 2) find a hermetically sealed substitute for this el cheapo buck 99 device!
