Alpine Disconnect Switch

[jdarling10]

Have a 2002 Alpine 38.5 and the switch located on the right side as you enter the coach does not seem to work. Regardless if the switch is on or off all DC lighting continues to work.
I would appreciate any and all help.

I dont know if this is relevant, but on my Newmar the 12v disconnect switch in the panel above the entry door does not disconnect the 12v interior power if the coach is plugged into shore power.

Thanks, but I'm talking about when dry camping with no additional power except battery. When I turn the switch to the off position it does not disconnect any 12 volt power. It is as though the switch

Joe and Micki,

On my '04 that switch does cut off the 12V power. Try turning off the other disconnect switch too, back in the battery compartment that turns off the chassis battery as well.

There is a solenoid that connects the house battery to the chassis battery under certain conditions. Maybe that is stuck, so that you are getting 12V power from the chassis battery. It seems unlikely that the disconnect switch would fail.

House cut-off is pretty straightforward--dont think battery charge solenoid is an issue here. Dash and chassis lights are separate switch in rear of coach. Not familiar with how switch is mounted on a FD 38 but assume you can get to the back of the switch and teat for continuity with a volt meter.

Thanks Jim....I will check that out ASAP.

Thanks for the info....are you talking about the fuse box in the bedroom area??

I think the main house disconnect switch leaves some light circuits on.

If you mean my post, no. I am talking about the second battery disconnect switch that disconnects the chassis batteries. It is outside the coach, most likely in the compartment with the house batteries/chassis batteries. (Or at least it is on my '04.) It is the same type of heavy disconnect switch as the one in the stairwell.

Jim,
It dosen't matter if both switches are on or off or any combination of positions. The power to the DC house lights remain on. When one of my Alpine buddies turns the entry switch off all DC power in the coach is off.
Thanks for your help...Joe

The switch may have been bypassed.

Hi Joe
we have a 2002 40 FDDS and today I checked and our battery switch by front steps turns off the 12 volt lights I don't know how this helps at least they are same year and mine is plugged in

Maybe your chassis and house batteries have been connected together so that when you turn the switch by the door off, power for the lights is coming from the chassis battery. Have you tried disconnecting the wires at the batteries and checking what goes off?
I assume you have disconnected power to the rig otherwise the battery charger will confuse the issue.

Hi John

Yes, however I think I am getting closer to solving the problem as each day goes by. I have a electriction looking at it now.

Thanks, Joe
