Electrical Schematics & similar questions

We have a 2013 LS37IK and I would very much like to find wiring schematics for both AC and DC systems. Our dealer LaMesa thus far has not been able to locate this information. Does anyone know how to obtain this data? Calls to Lifestyle have not produced anything either. We plan some boon-docking and will have a potable generator most likely the Honda 3000 although the 2000’s with parallel capability are interesting. The 2 smaller generators offer a backup, lower fuel consumption and less noise. However, the 3000 has electric start capability which is welcome by my wife. Understanding the RV’s electrical is essential and we are new to RVing although we have been in boating for over 50 years and the electrical systems are similar. All comments and suggestions are most appreciated.

From all the posts I’ve read on the three forums, electrical schematics are pretty rare. My thoughts are that there is guy in the plant that understands electrics and just goes for it. The switching for each model is pretty standard, but specifics are challenging. Perhaps you could generate your own by noting the 12v and 110v fuses/breakers and figure it out. Another thing that is common are the random junction boxes that get thrown in. We have a couple behind the curbside seating, behind the fireplace, etc. Good luck in your search and keep us posted.

Regarding random junction boxes – we all seem to have a lot of them. It has been explained that this was done due to thin walls and the desire to not overload/overcrowd the junction box. I suspect that it also has to do with modular assembly and wiring of slide, then connecting to the 5er harness, both 120 VAC and 12DC in separate junction boxes.

Do you have factory generator prep? This involves at a minimum a large relay switch, and often includes a subpanel for items that will be run by the generator. Unless you plan on always running a monster generator, you must always remember to turn off circuits in main panel, or have this subpanel installed. To start an air conditioner you need that relatively monster generator, making sure that water heater is switched to propane. If you don’t have any factory prep, you should think about doing your own inverter prep with associated relay switch at the same time.

Job 1= map out every outlet and appliance to a circuit breaker. Identify if that breaker is fed via shore power’s red or black lead. Identify the loads you will place on each outlet when boon docking with inverter only, and with generator only. Add up the amps – more than your generator(s) can handle?

As we are both new to RVing and Lifestyle this adventure will indeed be interesting. Thanks for the tip about random junction box’s. Yes we have the factory generator prep, however no generator. We have some exploring to do and appreciate the tips.

CaptainChuck,

Check out my post re old links for solar power. They are a great intro. View “unread posts.”

I have gotten a lot of great information about solar from Jack Danmayer. You can check his web site at: http://www.jackdanmayer.com/.

The input from everyone is very helpful and much appreciated. Our Lifestyle has a 50 amp service and 2 120vac power sources at the panel. Given the possibility of only a 30 amp supply available at a CG what are the options? Is an 30 amp ‘Y’ to 50 amp shore cord a viable option? Looking at portable generator options it appears we will be limited to units with a NEMA L14-30R outlet to power both legs. Any comments?

Capgain,

“y’s” and adapters bring to the 5er all of the amps that are at the campground power post. If you turn on more equipment/appliances in your 5er than the campground power can support, you will blow the campground breaker at the post or in their office; or your generator breaker. No big deal; just reset the breaker. Taken to extremes, you can create internal “brown-outs” that can damage appliances in your 5er.

Pretty safe using small 1500 watt induction heaters if on 50 amps; you will heat up 30 amp adapters pretty fast if you run two of them plus the hot water on ac versus propane. Count your amp draw.

I have seen ads for pigtails that combine/join campground 20 amp circuits with campground 30 amp circuits at the same post. While not the same as true 50 amp service, it can provide more than 30 amp “IF” everything in the campground is wired correctly.
