I have a 2004 Coachman Sportscoach Elite motorhome. There is a battery disconnect switch located at the rear by the radiator. This is a rotary type switch marked on / off. There is also a spring loaded type switch marked battery disconnect in the switch panel near the entry door with a small green light near it. There is no on / off marked by this switch as when it is pushed it returns to original position. Every now and then we lose al 12 volt power to the coach (lights, fridge, etc) and I notice that the green light near the front battery discinnect switch goes out. If I push the front battery disconnect switch the 12 volt power returns and light comes back on. This as hapen on numerous occasions and is a nusinance because if it happens while we are not in the coack our fridge cuts out. Anyone else encounter this problem? Anyone know what causes this to happen and how to stop it from happening? Also, what is the purpose f the front battery disconnect switch?

The front switch is probably for the chassis batteries... to be able to shut off batteries and keep parasites from draining them. Try turning it off... you should notice that you won't have any dash lights, power seats, etc.

The front battery disconnect switch cannot be turned off. Its a rocker style switch that is spring loaded and returnes to original postion after it is pushed. If I press on the switch while the 12 volt dc is ok nothing happens. If I press the switch after the 12 volt dc is gone the dc returns. I don't understand the purpose of the switch as I stated above there is a battery disconnect switch located at the rear marked on / off. The front switch has no markings of on / off, its just labeled battery disconnect with a small green light located near it and you cannot turn it off as it returns after being press.

My guess the front switch by the radiator is your CHASSIS battery disconnect switch to keep the engine battery from being discharged while not is use and/or dry camping.
The switch by the door is the coach (house) batteries switch, That switch is for disconnecting all 12 volt inside the coach while you are away from your vehicle. The switch at the door is controlling a relay/solenoid, If that switch is dropping out I would check the house batteries. I think you will find dry batteries and/or batteries with dead cells.
When you go to the front switch you are connecting all batteries together, Your coach it then operating off the engine battery. Check all your batteries for dead/shorted cells and WATER

The Battery Disconnect switch as you describe it is a rocker switch. Usually these work such that if you press the top, you turn it on. If you rock it down, you turn it off. I am not sure what you mean by front and/or rear switches, mine is located at the steps and can "accidentally" be bumped to disconnect the battery. Yours may be a 3-way switch though I have never heard of a coach with a 3-way setup. Try going to the coach and rock the top of the switch. Lights should go on. Now try rocking it downwards, the lights should go off.
That is how mine works -- Frank O.

You probably have one of those pressure on/off switches for your remote battery disconnect solenoid.
Are you connected to shore power when you press the switch with lights working and nothing happens?
If so, your converter is most likely still providing 12v to power your 12v system in the coach even though the disconnect switch has opened the circuit from the battery.
When disconnected from shore power and with your interior lights and refrigerator on, try depressing the switch and see if it disconnects power to your 12v system, then depress it again it should restore power.

The coach is a dp and there is a round switch at there rear marked battery disconnect and can be turned on or off. This switch is for disconnecting the chassis batteries. There's no problem with this switch.
The other switch is located near the door with all the other switches (entrance lights, outdoor lights, step, etc). Its the same shape and size as the switches for my lights, step, etc. They are all rocker switches and there's no on or off with the battery disconnect switch as it is with the other switches. As I stated its spring loaded and can only be in one position at all times. When I press the switch to reset my dc it springs back to its original position by itself. It's not a 3-way switch, just 2 positions. I have tried holding in on the switch for a period to see if my coach dc would turn off but nothing happens.
All I know is that when I lose my dc (don't know why) I get it back by pressing on this battery disconnect switch located by the door. I just press the switch, it springs back to its normal location and my dc is back. Also, there is a small green light located by the switch and this light goes out when I lose my dc and comes back on when I press the switch to restore the coach dc.
All my batteries are ok.

Yes LVJ58 I was connected to shore power when I tried pressing the switch. I will try your suggestion and try pressing the switch when disconnected from shore power. Will post what happens when I try this. Still don't know why the dc trips off though.

beerman5050 if it keeps disconnecting, it could be faulty and need replacing, unless it's some type of thermal circuit breaker switch. If it's a circuit breaker then there could be some overload source on the circuit or it could also be faulty.
Hopefully you'll get the issue resolved, good luck.
