Burned Main Circuit Board
OMGosh! I knew I messed up when I could smell that smell of a circuit board burning. I have a 2001 National Caribbean that had a bad boost relay mounted behind the main circuit board at the rear of the coach. After disconnecting the house batteries I removed the board and replaced the relay. I took pictures of the board and remounted the board as the pic showed and then reconnected the house batteries. I heard the battery disconnect relay energize and there was some sparking on the reconnect of the positive house batteries. I didn't see any issues after the connection so I went to the dash panel, turned on the disconnect switch and then the ignition but didn't start the engine. Then I operated the boost switch and I could hear it switching. I then started the engine and went back to the main board and that is when I smelled it burning. I immediately went and shut the coach down and came back to study the board to see where it was burning and found it. UGH! Does anyone know what I need to do to repair or replace this board? Any help is very appreciative! Thank you,

Re: Burned main board
Hey Richard, thanks for the link. It got me where I needed to go to get the Battery Control circuit board. They are also sending me the schematics and troubleshooting info so I can repair this board and keep it for a backup. Many thanks!

Hope you get it going easily!
Please let us know how it goes and what you determine was the cause of the failure.
Iím going to be replacing the boost solenoid on my 02 Tradewinds soon.
Thanks for your post.
