I know I'm a little late to the party, but here's my 2 cents worth.

Here is the original WRV battery schematic from 2001. I have also attached before and after pictures of my battery compartment.

Please note that the top hold downs on my batteries are ALL plastic. I cannot stress enough the importance of (A) make sure batteries have hold downs and (B) make sure hold downs are not metal. There is a large amount of energy stored in this compartment and a lot of vibration and shaking around happening.

Here's my battery compartment. It was like this when I bought it. I suspect that this was the way WRV did it originally. A buss bar for the chassis positive and one for the house positive could make this a lot neater. I haven't done it because it works like it is and it would be expensive to do.

another thing that has slowed my project is I haven't found a schematic of the wiring in the battery compartment - one that shows all the components and the batteries. Does anyone have a drawing for this? I've been thinking about drawing it myself.

...will try to attach a pic later....my 2003 [early 2002] looked just like yours, coming from the factory.….early on, I used the main fuse block on the wall as a buss bar to distribute cables and eliminated the combiner solenoid cables--never really had to use that feature-- 17 years and 190K miles....have since added a negative buss bar for the negative house side when I upgraded the solar....

As others have noted, while so many details of the Alpine were very well thought out and quite clever, the battery cables were NOT.
It's almost like they just let Brad, the factory battery installer guy, figure it out by himself----"here's 12 cables, make it work."

Iím working on the schematic. The big piece I s my battery isolater. The cable on the left (facing) goes to the house batteries. The center cable should go to the alternator. I havenít verified that. The cable on the right goes in the engine compartment too, but has to eventually work its way back to the chassis batteries. Iím guessing there is a block of some sort in the engine compartment where the connection is made. The two small wires are from the battery charger. Can any of youse share light on this so I donít have to crawl under my coach?

Do you really think that is factory work?
Does the init have a RVIA sticker?
I don't know for sure but doubt RVIA would agree with that many connections per terminal or how they are attached.
I am familiar with boats and ABYC (similar voluntary compliance by mfgrs) and know that would not pass a survey. Also use of wing nuts is a no no on boats. To me boats and RVs are similar in many aspects... vibration, environment, etc.

Not sure if mine came from the factory like this or if the PO installed these but they certainly cleaned up the battery bay

These batteries are all gone now, replaced with a Lithium battery bank moved inside the coach but hopefully, you can see the 2 positive bus bars in the back on the frame rail?

Not really sure what you are looking at. Maybe what you think is wing nuts is really fuses and the fuse holders. I think the big cables are factory. There may be some add-Ins after the fact with small gauge wire. There is an isolater block (not shown) for the solar panel. There are some other blocks on the ceiling that I haven’t figured out yet. One of the objectives of using buss bars would be to get all the small wires off the battery terminals.

The chassis batt wire may come from the positive starter terminal.

The 2 fuses may be going to a Trik L Start

The charger in my coach is called an echo charger and it is in the compartment with the inverter.


Here is what I have. This is first draft. I haven't checked it to the point I have complete faith in the drawing yet. It may or may not match your coach (mine is a 2001). The drawing only shows the "big" wires. There are smaller wires connected to the battery too. I do NOT have the buss bars in my coach yet. The wires shown going to the buss bars are currently connected at my battery terminals. There are 19 different cables. I haven't put sizes on them yet. There seems to be 2 sizes - big and little. If you know the sizes, please share.

In my 2001 the 3 wires in the ceiling go to the refrigerator, the suburban heater and the power to
the driver seat and passenger seat

I'm not sure what you mean. I think you are referring to the block with the 5 wires.
