Congrats!!!! Great looking coach!!!

007..Yes, the coach is plugged in and the battery cut off switch is on. I have also tried the battery boost switch but still nothing. I will check the chassis engine battery for a possible loose ground cable to the chassis frame. Is not the bird supposed to keep it charged up? This is the third time this has happened. Thanks for the advice.

You may have a bum solenoid and the Bird will charge all your batteries when shore line plugged in. Boost button connects house batteries across start relay through solenoid.
Here is link to parts for many items in your coach.

I have had this problem 2 times now no power to the ignition or dash acts like completely dead battery. Batteries have good charge, checked connections at distribution box and everything under the hood then it cranks and runs fine.
Any ideas

Welcome to irv2 Jeff.
If your starter battery is good and if you have tried to use the boost button there is a 5 amp fuse in the Bird System that might be blown or the fuse holder spade clip has fallin off one of the spades of fuse. Fuse maybe hidden behind the heavy battery cable of solenoid.
The spade clip on mine eventually fell off the spade of fuse on mine check it out.
Isn't your coach still under warranty from Ford chassis and the Ford forum may have a answer for you.
In my signature below are links to many links that will relate to your Newmar.

Would that be in the black plastic box with the clear cover over it under the hood
Thanks Jeff

Found the problem why my chassis battery was loosing charge. There is a 7.5 fuse at the bird that was blown. Replaced it yesterday and seems like it is holding its charge now.

[wolfwgn]

Where is that fuse located
Thanks Jeff

Here is the picture of Bird the fuse would be on right lug of left solenoid.
As I said before maybe behind battery cable, difficult to spot.
Mine was 5 amp in my year coach 03, maybe higher in newer coach's ?

I am still having problems with my chassis battery draining down while I am plugged into shore power. I have no idea what is causing it. All batteries and connections are good. Any help would be much appreciated.

bo1116, have you ever had your chassis battery removed and had it checked out at a parts store.
You may have a dead cell in battery if it can not hold a charge.
You say house batteries are OK so Bird System is working.

3 Month update September 2014 Four seasons ford Hendersonville NC thinks its a loose ground picked up 400 mile trip died again. I can grab and wiggle the main wire harness that comes out of the distribution/ junction box under the hood and get power back to the dash. will fire called Ford roadside assistance and another tow to a different dealership in South Carolina the had had it for 3 weeks and have had it die once while driving but did not have a diag computer connected so they still cannot determine cause. Last .6 mile trip to get it to a location that a wrecker could pick it up died 5 times very hard to steer and stop not running and no power.
Any ideas or recommendations at this point 4 months cannot use motorhome will not stay running
not safe to try and drive with no power
Thanks Jeff

Jeff on the fire wall you have many harness cables that plugged together and one of them maybe loose and has collected water penetration and may need cleaning by good cleaning spray for electronics.
Once you have done this wire tie through wire harness's to hold the two plugs together.
If its the ECM cable there should be clamps to hole cable harness to ECM Modular.
