2003 Monaco Windsor Wont Crack

I have a 2003 Monaco Windsor that will not turn over. Put brand new chassis batteries in and cranked just fine. Went away for 5 days, and come back to prepare for a trip coach won't crank. However on battery boost crank just fine, let go the boost button coach dies.

Take the Chassis batteries out to get tested. Batteries just fine. As I'm putting them back in I get a ark on the last post! Take the batteries back out and go buy new ones as I never trust a battery that has had an ark.

Get the new batteries back in now I don't even get the coach to turn over.

Any help you can give is much appreciated. Looking for the wiring diagram please, for 2003 Windsor 40pst.

Thank You

Here is the Chassis wiring diagram for a 2002 Monaco Windsor, should be similar to the 2003.

When you open it and zoom in it will be blurry, hit CRL5 and it will clear up.
You can use the search function to find thing, I used IGN and found 51 hits.

Initially I would have told you to check the battery cut off switch but based on your last portion that's not the problem if you are using the battery boost switch and it won't turn over. My battery cut off failed causing the same initial symptoms.
