discontinued pc boards in dp rvs, help

[starmack2001]

Need help locating a pc board for my 2004 Monaco Dynasty. It has been discontinued, according to Rev RV , the monaco parts supply. Intellitec doesn't have it either. My inverter and transfer switch both went out and took this board with it. It's the board in the in the rear by the engine that has the front/rear ignition switches on it. It's number is 84-00825-BBB, Monaco BCC PCB, made by Intellitec. I had a tech replace the inverter, transfer switch,and the burned relay on the board. But it's still not functioning properly. He jumpered another relay that this board controlls and we now have power in the rv. But I need to repair or replace this board. Also, I've had a parasitic drain on my engine batteries that no one has found yet. I've been putting a trickle charger on them and turning them off to maintain charge. He told me to just connect a pair of jumper cables from the house batteries (4 series wired 6 volt golf cart) to the engine batteries and let the inverter charge them along with the house batteries. Good or bad info on the battery charge? Does anyone know where I can get the board repaired.

It appears the only discrete device on that board is a voltage regulator. Everything else (including the voltage regulator) are readily available from places like DigiKey or Newark, Allied Radio and others.

Are you certain the board is that failed?

If so, PM me if your not comfortable repairing yourself.

Give Dinosaur Boards a chance:

Dinosaur Electronics Home. High quality circuit boards for RV appliances.

Don't know, but they may have an ideal or a board.

Send out to good pc shop for repairs or look online for circuit board repairs.. but examine closely and look for burnt marks.. solder spots.. loose connection.. many times you can spot the problem and order online for less than a few bucks and solder yourself .. eBay circuit board repairs.. that should get you close..
Good luck and keep us posted

If you look at the 3rd picture it has an Intellitec number. This is the one to search for.

You might try contacting Visione RV https://rvparts.visonerv.com/


You should also contact M&M, they repair Intellitec boards and if anyone can help it would be them. https://www.mmrvelectronics.com/intellitec




Not sure with your make/model/year coach but a number of Monaco owners have installed a Bluesea ML-ACR to improve their house/chassis charging systems.

I did this on my 2002 Windsor (I will admit not nearly as complicated as yours) but I was able to remove the BIRD, Lambert 415 Maintainer, and Isolation Solenoid and replace with the Bluesea. Do a search and you may find someone who did the same thing for a similar coach.

Also in photo 3, the IGN relay is damaged.


Someone may have hit it with a wrench while wiring to the adjacent
post terminal, and plastic may be inside the relay.


Or (less likely) a catastropic failure could have blown the side out.

Easy and cheap to replace. Whether it impacts the operation of the control …….

From your pictures, there's nothing I can see that indicated that the board itself is damaged. Any competent electronics tech should be able to troubleshoot and repair it, even if the application is completely unknown to them.

there's a supply chain issue with certain components like the aforementioned VR, but equivalent parts can be found. It's not a satellite lol.

Some of those solder joints look like they could use a rework. Common problem. That relay needs to be replaced too

Thanks for all of the help. The relay was damaged when the inverter and transfer switch went out. Part of it was my fault. I was trying to bypass the transfer switch to obtain 110 in the rv and hooked up a wire wrong. We think that's when the relay blew. No physical damage (wrench hitting it, etc) was done to it. We discovered it after the new inverter and trans switch was installed. Everything is working now EXCEPT that the big relay (item 10) will not stay energized and ALL of the 12 volt system goes from the blown relay (board) to the #10 relay and then energizes everything else. We have everything working by jumpering the #10 relay and keeping it hot. Item #10 reminds me of an old chevy starter solenoid (rebuilt many of them while younger) without the gear housing on it. I rebuilt the original one on a trip in Utah one year while I waited on a new one to come in. Internally, it was a starter solenoid. That's why we think that there is something wrong on the board. We replaced the blown relay on the board (#5) and it still will not keep the #10 relay energized. That's why I'm looking for the board or a repair shop. I'm trying to locate the other components on the board so I can replace them and see if that helps the board. I'm surprised that Monaco/Intellitec discontinued this board (#5) when it is so widely used in DP motorhomes. I bought it from them about 6-7 years back so that discontinued status is recent. This board went bad on me back then. Now I buy spare parts in pairs because of the possibility of obsolescence.

The Intellitec Big Boy isolation relays are still available.

Several Monaco owners have replaced the Intellitec system with a Blue Sea automatic charging relay.

Hope you get it working.

Got it repaired. The real culprit was item 10, the Big Boy battery isolator relay. I had a spare old one that I had taken off of the rv 6 years ago. I had rebuilt it (it's basically an old style GM starter solenoid without the gears on it) and kept it for a spare. Put it in and all systems are working fines now. There was nothing wrong with the other board at all. We had already replaced the small relay that had a hole in it on the "bad" PCB. My tech kept telling me that this Big Boy would not stay energized and he had jumpered across it to make it work. Well, to me that mean that the relay is bad if voltage passes through and everything works by "jumpering" or removing the relay from the circuit and basically hard wiring it. Essentially the same thing. Why he didn't understand that, I don't know. I posted pics of the relay with the jumper and after I removed it from the rv. Out of curiosity, is this the "bird" that I've read about in other posts?

Pretty much - getting a handle on the how the B.I.R.D. relay works is hard - it mechanically latches, and our minds expect an electrical latch.

Good you got it figured out! And knowing that the damaged had been replaced was important to understanding WH that you were dealing with. 😀
