People seem to consistently over estimate the ability of their TV alternator to charge their RV batteries.

Did the systems WORK before you replaced the Batteries(even tho bad batteries)? If so, 99% of the time when systems worked BEFORE replacing the Coach batteries and then you have operational problems, you connected the new batteries wrong or you missed a cable that should be connected. Doug

So we got a mobile repair tech out and there's some kind of disconnect to the house batteries. Alternator, solenoid are fine. Power is going into the control board but not getting out to charge everything. Correct part is ordered will be here Friday, in the meantime we are charging the batteries with a device the tech lent us. We have power generator heat and are parked safe. And enjoying the lovely blue heron farm and cheese company in the meantime. Will post updates. THANK YOU to all who responded with help [emoticon]

This is one area where motorhomes usually do much better than tow vehicles and trailers. The battery combiner circuitry on a motorhome provides a decidedly better and higher-capacity connection between the chassis and the house batteries, and usually the house batteries can get a substantial charge over the course of a day's driving.

Even if house bank is discharged (not likely with new batteries and long drive), the alternator is more than adequate to have them fully charged at the end of the drive.

Jinian,

It is great to hear that you got it handled.
Thank you for coming back and closing the loop on this.

So often others have come here for advice or assistance and just vanished. We never hear what the real issue turned out to be.

Did you guy give a possible reason for the failure?? (Hope - hope)
