58 DB bad a/c trigger control box location

[bmac]

So I’m pretty sure I’ve got a bad trigger on my salon a/c. I can not locate the control box where the 4 triggers are located. I looked through the parts manual and it’s listed as “Not Shown”. I’ve looked where I would expect to find it and haven’t found it. 2006 58DB, anyone know where the box is located?

Just in case anyone looks for an answer to my question above; Sea Ray customer service did another great job in telling me where to look for this relay box. It is located behind the port salon couch under the MDP (not very accessible). I found it easiest to get to the box by removing the center couch cushion and frame then climbing into the void. BTW, this is the first time ever that CSR members did not have the answer to a question I had. Maybe all the 58DB owners are out on the high seas on their boats

Is the bridge A/C trigger on the unit itself?

Carter, since the bridge a/c has a dedicated pump I don’t think it requires a trigger.

I thought it would have a trigger to start its pump...

BTW - I want a picture of you climbing into the void behind the port salon couch!!!

So, I finished replacing the trigger last night. Because of its location what should be a 10-15 minute job took four hours start to finish. At labor rates here that would be $600 for labor to replace an $85 part. Here's some pics and even the one Carter requested;

This is the couch behind which the offending trigger is located.

Backrests removed

That's the relay box behind the port couch, where the triggers are located. Looks relatively accessible but that picture is deceiving. Even with the aft most back rest removed I can't even reach the box cover much less replace electronic components and with the aft most back rest frame removed the opening still wasn't big enough to work through, so that went back on. Here's a better perspective of where the box is located.

So off came the center back rest frame to gain proper access.

And here's Carter's requested picture of me in the space. I actually had to lay on my side to reach the box and remove and replace the trigger.

Lastly, this is what the offending relay box and trigger look like for those who wondered. The triggers are the four devices labeled 230V. Knowing how to use a voltmeter as well as which terminal points you need to check in order to determine which trigger is bad is very helpful. I now know more about this aspect of marine air conditioning systems then I ever thought possible. The end result is the admiral is once again fully air conditioned. All is well in the universe.

Thanks Brian! Was this the trigger that you ordered?

I think you need to frame that last picture!!!

No I ordered this one, which is the OEM direct replacement.

For the few bucks different I wasn't really interested in experimenting with the dual voltage element.

Also, I don't think that picture will wind up in any frame on the boat.....or anywhere else for that matter. It will live on only on CSR.

Brian - how did you figure which unit was bad? The trigger relay turns on the water pump - am I correct?

So it was easy to figure out which unit because my aft Salon unit intermittently tripped on PS HI. First I flushed all the units through the strainer cap but it continued to trip. I then shut off all four units and started the suspect unit by itself. No water flow, so maybe plug gage, but checking the raw water pump showed it was not running. So that confirmed an issue with the signal to start the pump from that unit, most likely a trigger. Next, I located the relay box and checked the two terminal points associated with each trigger. I operated each unit by itself so that I not only could determine which trigger was bad but also which trigger was associated with which unit. Three of the trigger terminal points had 230V across them while one had 0. That was the bad trigger. By the way, the reason I told you the Bridge AC likely doesn’t have a trigger is the the 230V to the triggers come from the A/C unit itself. There are two sets of terminals on each unit; 230V to the unit and 230V to the pump. The terminals are marked on the unit. So I would imagine the 230V from the unit on the Bridge goes straight to that pump, though to be honest I haven’t checked that.

Thanks Brian. Great info.
