Hi,
Relays can fail. I'd be glad it failed in the "on" position.

How do know it did not turn off the batts?
If plugged in to shore power. Converter still gives you 12 volt.

If the coach battery relay has failed, if i unplug from shore power i should not be getting any power to the 12v items, correct?

As with most things with RV's, it depends on the manufacturer. On my previous rig (97 Winne Vectra) all the 12 VDC loads were de-energized with the Master Switch solenoid. However, on my current rig some of the 12 VDC loads (steps, levelers, slides, smoke & CO detectors) remain powered up unless I pull the fuses. The remaining loads (lights, control power to the fridge, furnace & A/C, etc) are tied to the Master Switch solenoid.
Just to add to the confusion, I have some loads (dash radio & outlets) that are powered from the chassis battery, which are not impacted by the solenoid.
Probably the best indicator is your interior lights because most likely they are powered through the solenoid.

Check the fuses on the bottom of the solenoid. Check for 12 volts on the terminals for turning on and off. While by the solenoid have someone push the button for turning the battery on/off and listen for the clunk of the solenoid energizing and de-energizing. Remember the solenoid only needs a quick 12 volts to latch or unlatch the solenoid. If it seems to be working but still not turning the battery off, it could be arced contacts in the solenoid. Most can be taken apart and cleaned up.

Are you saying that the switch does not disconnect the batteries when the switch is pressed to OFF or that the switch won't stay in the OFF position when pressed?
That switch on many motor homes is a momentary switch and returns to the center position when released.

Yes the switch retuns to neutral when release, but should not the green lite on the switch go out after pressing the off side of switch?

My particular switch does not have a green light but it seems logical that it would go out.
If you are unplugged from shore power and have lights or other 12 volt items working when the switch is pressed for off then I would say there is a problem.
If you do have a solenoid issue I can post some diagrams that may be helpful.
