New to RV...Lex 255 ds

[snags1962]

Don't have a manual yet...where to switch power from 110 to house batteries and or generator? Want to do a one nighter but don't want to end up w/ dead battery. Anyone have a manual for a 2008 year ?

Thanks,
Craig

Craig,

Welcome! I purchased a 2006 255DS last spring and have found help with many things on this side.

I have "component" manuals (fridge, heater, generator) for the motorhome, but nothing about how to use the whole thing. I don't think they make those!

With the exception of the oven and AC (and outlets) everything runs on 12 volt. So it works the same if you are on battery, plugged in or running off the generator.

So if you plug in the AC and oven (halftime) both work and the outlets come alive (and the converter charges the house battery). Same when you start the generator (it delays power until the generator stabilizes 1-2 minutes).

When you drive down the road, it also should charge the house battery (I am having an issue with this and need to look into it).

Best of luck!

Craig,
There should be a transfer switch that switches from generator to shore power when you plug in. It is under the bed in our coach.

NoviBill,
The battery isolator is located in a box beside the house batteries. After a delay of some minutes the chassis battery is connected to the house batteries via a solenoid in this box. It works the same way in reverse when you are running the generator or are on shore power so it keeps the chassis battery charged while the rig sits idle.

Both of these things get cranky when they get old. Especially the battery isolator because it gets switched so often. The contacts get burned and pitted.

dontay Thanks!

I also lost my mind one over the winter and tried to start the generator without first hooking up the house batter. Something "blew" and the house lights no longer work off the truck battery. I checked for blown fuses but did not find anything..

My plan is to replace (as much due to age) all the relays near the couch battery and if that does not fix it then debug some more...

Are you running the engine when trying to turn on house lights? If the isolator circuit does not see a high charging voltage on either side it will not activate unless you push and hold the emergency start switch which is on the door side of the driver's seat on ours.
And remember the delay time. This is also defeated by the emergency start switch.
