Do any of you know of anyone on the Eastern End of the country that rebuilds/repairs circuit boards?? I have a place on the west coast that does this but would love to have someone closer.    Thanks in advance for your help!!!

worth a call.

Do you have an ECU problem?

No .It is a board on CC Prevost conversion that most all of the 12v lighting run's through .One of the relay's on this board was fried when I got the coach and I would like to get it fixed.

If you are sure it's the relay on the board. I can walk you through how to do it yourself.

It will take a magnifying glass for old farts like me. Read the number on the relay and google it. Of course buy two. The shipping charge will be more than the relay.

You will need a fine tipped soldering iron, some copper braid known as solder wick, and fine electrical solder.

Turn the board over, and locate the protruding prongs for the relay.

Hold the end of the braid over a prong, and hold the braid to the prong with the tip of iron. The solder will melt and flow up the braid. You may have to cut the used end of the braid several times to clean out one hole. When you have cleaned the solder out of all the relay prongs, it should easily detach from the board. If it doesn't come out easily, then clean up the prongs some more.

Put the new one in, and solder it to the board.

Hope this helps.

I had a similar failure with a board full of relays in an unfriendly location as well  I decided to use a automotive cube relay( mine was 24 volt)  removed the control wires from the board, and the 2 from the relay to the lights and connected to the cube relay. problem solved without trying to remove the circuit board. 
Worked great.

Hope that helps

Good point Dick.

There is a known relay failure on the air conditioner controls for the basement air units in the 2000 era Newells. The boards are becoming as scarce as hen's teeth. A few of us have taken leads from the circuit board to power a remote heavy duty contactor for the compressors. That seems to have cured the chronic circuit board failure.

Think you may have the right idea !! I am going to check into doing it that way .These relays are NFC  MR331-N11 which must be a defunct business .I can't get a computer hit at all on them!!
