Battery disconnect wiring

I have a used 2001 Fleetwood Prowler 5th wheel with 3 popouts. I have
new batteries but they drained while in storage. It is also equiped
with a Batt Disconnect switch. I found the disconnect relay and it
works but when energized it does not seem to disable anything. It has
2 red number 8 wires on the line side and only one small wire on the
load side. I requested and received a trailer wiring diagram from
Fleetwood but it is so dim and smeary it is not usable. I am convinced
it has been rewired. Can you tell me what all should go through the
disconnect relay. Should everything go through including the popout
drive motors and the front feet motor or just the circuits in the
trailor. I noticed the battery positive terminal has 5 or 6 smaller
wires connected to it also. I haven't tried to sort anything out yet
until I know for sure how it should be wired. Thanks

How about your propane sniffer and CO detector and/or smoke detectors.

Thanks for your input. The only time I would have the batteries and
ckts disconnected would be when it is storage. I store my unit in a
storage lot where no one would hear any alarms if they did go off so
they wouldn't be of value there anyway.

She is telling you that your co/propane detector is what is running
your battery down.  It is hardwired to the battery and bypasses the
disconnect switch.  It's always on.

So when you stored it, you disconnected the batteries ?
Then when you went to pick it up, the batteries were dead ?
If so, are you sure the batteries were fully charged when you stored it ?
How long was it stored ?
How old are the batteries ?
If they are 6 years old they may need to be replaced.

I didn't disconnect the batteries I just turned off the battery
disconnect relay. The unit was in storage about 2 months and when I
picked it up nothing worked. I checked to batteries and found them to
be down to 6 volts. I assume the batteries were charged because we
were camping prior to storage and we were plugged into the truck and
plugged in during camping. The batteries were newly installed when I
bought the unit earlier this year. I removed both batteries and
charged each one for about 12 hours after I found them low. What all
should be disabled with the battery disable relay is off ? I found
that everything in the unit still seems to work (lights, fans, popout
motors, -ect) when the battery disconnect relay is turned off.

If you aren't connected to shore power, and the battery disconnect is
turned off, nothing should work.  Except maybe the CO/Propane
detector.  If all your lights and stuff still work, then the
disconnect is not working.

I checked the relay it is working but only has one wire ( #8 or  10)
on the load side of the relay. I suspect the wiring has been changed.
Would the popouts and front feet go through this relay also ? It seems
like that would be a pretty heavy current load. If anyone has any more
inputs or a headsup that would be helpful I would appreciate your
inputs. Thanks for everyones help I guess I will jump into the wiring
and try to figure out what was changed.

That isn't a battery disconnect.  That relay is probably used to
switch the power from the converter to the battery when shore power is
removed.  You don't have a battery disconnect.

The disconnect relay works, I checked it. It only has one wire (#8 or
10) on the load side of the relay. Someone must have changed the
wiring to bypass the relay. Should the pop outs and front feet also go
through the relay, seems like it would be a heavy current load.

Did you read what Frank Tabor wrote ????????
He said you don't have a battery disconnect.
In an earlier post you wrote.......I found that everything in the unit still
seems to work (lights, fans, popout motors, -ect) when the battery
disconnect relay is turned off.
The reason everything is still on is because YOU DON"T HAVE A BATTERY
DISCONNECT !!!!!
What you think is a battery disconnect.........ISN'T !!!!
If you "jump into the wiring and try to figure out what was changed", you
are going to screw up something and have a mess on your hands.
Unhook a battery terminal when you store it and everything will be fine.
You are making a huge problem where none exists.

They make a knife disconnect that goes between the postive battery
terminal and the postive battery cable that once installed, is just a
matter of opening the blade.  Works great for me!!

Thanks again for all your inputs. I read the Oct 15th postings this
morning. The switch on the control panel that controls this relay is
titled Battery Disconnect. Maybe this means something other than I
thought in this trailer. I will see if I can get an owners manual from
Fleetwood and it may tell me it is for a different purpose? I will
install a knife switch disconnect for storage as suggested by Tom J.
