After a lightning strike on the mast of a nearby boat in our marina, the charge propagated and caused damage to several nearby boats, some severe.? When I returned to my boat, I found damage including the starboard aft Gulper shower sump pump was running continuously with no water in the sump.? I disconnected the red lead from the shower pump relay referenced above to turn off the sump pump (Scheiber Ref. 36.16112.00).? I am thinking the shower relay was damaged by stray current and I must replace it.? I cannot find it in the Beneteau catalog, but I found it elsewhere online for $119.? Please, before I experiment by replacing this relay, does someone have a better idea???

Thank you, fair winds, Gary

Hi Gary,

I used to have the same issue, have a look in here,

I hope that might help.

Your question was posted about a year ago when I was looking for solution myself.

Scheiber relay not necessary. Found better solution using Hella delay relays, which have selectable time to control how dry you want the shower sump. If you are like me, you don't want the standing water left when the fixed time ends on oem relay. Also sourced the float switches so can add to other showers if needed. ?

I've got pics, instructions, and part numbers. Just never got around to posting. Will do when get to office. If I forget, email me jim@....

Thank you.? I am in the U.S., so I will first seek a solution in the U.S.? Have you had any difficulty with corrosion?? This relay is exposed to a high-humidity area of the boat.? That makes me wonder about corrosion.

Sorry.? I accidentally replied to my own message.??

Thank you.? Your email address did not come through.? I will wait for your post, or you could email me at geglinto@...,?if you wish.

Gary you need: HELLA Relay- 996152131

You can find them on ebay, or Summit Automotive has them in stock in the US for $40.?

This is a sealed delay OFF relay, selectable from 0-900 seconds. You will likely need between 10-15 seconds. (be careful, there is a similar part number ending 151 that is delay ON, you don't want that)

Basically, you remove the leads from old relay and slide on to new, modifying the wiring to split ground and power. A wiring diagram for the relay is hard to find and doesn't come in the box, so I've included it with a few pics. If you note my install, you will see ground split between relay and pump with a butt connector and heat shrink. Not shown is constant power split in the same way between relay and a lead from the float switch(non-polar, so either switch lead will work). The other float switch lead will tie to post 15 on the relay.

The beauty of this relay is it allows you to adjust the time to drain the sump dry, keeping it much cleaner and much better smelling. Plus it's about 1/3 the price of the Scheiber. ;)

Set the time by turning the screw on relay(and switching dips switches as necessary), to leave a little liquid in the line. That keeps the gusher pump from running dry and also keeps the prime so it doesn't take as long to start up on next use.

I've also included a pic of the Side Mount Horizontal Float Switch(for those that need to add a switch and relay to other locations on the boat) For example, my 500 had only manual switches in the?port side heads.

I found the exact same switch as the factory on ebay two for $9. It shipped from China, so I had my doubts, but they ended up being identical to what was there, and only took to weeks to arrive. The size you are looking for is m16 body, and 92.5mm long, or roughly 3 1/2 inches.

As a final note on the float switch, if you mount it a little closer to the bottom of the sump than the Lagoon install(not too low or it won't turn off) it's easier to find the exact timing to leave liquid in the line, but still fully evacuate the sump. I also retained the manual button in my retrofit installs, just in case of a failure. As always, keep a spare switch and relay on board. Cheap, and you'll be a rock star when one dies and you have guests on board.

Hope this helps!

Here is the relay from amazon



Also, here is the thread from cruisersforum, which has the relay with a variable timer.
