Does anyone have an electrical schematic plan for my coach? It's a 2001 Beaver Patriot Monticello 40' 330hp CAT.
I am trying to find where a fuse might be for the Hydro Hot system.
Orman Claxton is kind enough to help me try to get my Hydro Hot system working but a "Low Battery Fault" light is showing on my Hydro Hot panel. My batteries are fully charged.
The diesel switch on the wall beside the electric switch does not turn green when switched on. The electric side of the Hydro Hot works.
I have a breaker in the panel marked Hot Water Heater, but I confirmed that breaker is on.
He thinks it's a fuse and asked me to canvas the forum for some help with the schematic.
If you know where the fuse might be that would also help.
I feel like a kindergarten kid with this new coach! So much to learn.

Les,
In the box where your breakers (120v) are located there is also the 12volt electrical fuses for the coach. You can check those fuses. However, if the "low battery fault" is lighted then my guess is that your 12 volt supply to the system is working. I think there is a small reset button on the HH panel that may need to be reset for the system to work. I am still confused because you said the electric part of the HH is working. That also would lead me to believe that you are getting 12volt to the HH. Is your electric switch in the ON position and is the light ON as well?
-
I checked those 12V fuses when I checked the circuit panel.
I tried the reset button on the Hydro Hot panel. I even took the cover off to ensure it was fully pushed.
Even with the electric on the light is on.
The electric worked this past weekend. Just not enough hot water to fill the sink to do dishes.
Water in the boiler is full.
Orman thought there was another fuse possibly in the battery compartment.
He also wanted me to check that I'm getting at least a full12V to the Hydro Hot panel itself.
-
My coach is quite a bit different than yours, Les, but there is a circuit breaker in the Big Boy and big fuse box above the battery banks that my schematics say is "Coach Heat". That group of circuit breakers, 5 altogether on the same buss, is separate and somewhat isolated from the other 12v. breakers. So Orman is probably on the right track. You may have a fuse instead of a circuit breaker. Mine is 20 amps on the end of the buss; at the opposite end is the solar panel breaker separately wired and not attached to the buss arms like the rest. That may not apply in your case though.
Someone else will have to clue you in to which one of probably several is the proper one, but you could still voltmeter test any you find for continuity.

My schematics show a fuse in the isolator box above the batteries in the upper right hand corner (right of echo charger). It's the left most fuse in a group of 3. shows as a 20 amp. I am going to try to post 2 pics but I'm running about 50/50 when it comes to posting pics.
-
Rotate the first pic clockwise.
-
second pic is overall of most of the page. 3 fuses upper right. Hope this helps.
-
Those 3 look more like circuit breakers than fuses, Jerry.
Regardless of which they are, Les could check that voltage exists on both sides of all he finds.

They are not circuit breakers that I am familiar with, not saying they aren't! LOL
They look like some large current fuses that I've seen in the navy. Here is a pic that I was planning on asking you guys about until I just found it a few ago.
-
Remember that I am very new to these MHs. I could be wrong about everything!! The pic on the schematic looks like the isolator box and the pic I took may or may not be it but it's labeled for the hydra hot so I didn't think it could hurt.

Jerry,
Didn't see in this thread where you had checked the DC voltage at the h Hot. I'm emailing you a HH troubleshooting manual which will take you through the steps to figure out why your diesel burner isn't working.
Steve

Jerry you are very lucky to have all the schematics for your coach you should copy them and archive them here so others down the road will have access to them as coaches get passed down schematics get lost and some owners will not have any like the rest of us unlucky souls here. The photo you took appears to be fuses. The bottom fuse appears to be a 300 amp or larger Magnum fuse. Usually used between the isolator or inverter and house battery bank.

Thanks Steve, it was Les that needed the schematics for the HH, I was trying to help with the schematics I had hoping they were at least similar. My set is labeled for the Patriot but I noticed that the actual drawings inside are for a few different types of coaches made by Beaver from 2001 to 2003 according to the dates on the drawings.
Gary, as far as copying the schematics I will copy in PDF when I can find a scanner large enough without having to spend $100.00 to do it.
-
I've been meaning to contribute a copy of the diagram book for our coach, but what you need to understand, Gary and Jerry, is that it isn't as easy as it would seem. First of all, it is no small book at least physically if not in number of pages, so a lot of time is involved regardless of methodology.
I've tried photographing it, but getting the lighting and other parameters just right to get nice, easily legible renderings has proven more of a challenge than one would think, and having some experience with professional techniques over the last 50 years, I say that with some confidence. Occasionally I've produced adequate results of individual pages or parts of pages for individuals with similar coaches to ours, but for the Coach Assist section I want imagery as good as possible so that component ID text and graphics are without ambiguity and as interpretable as the original.
The only way to adequately achieve that is with a good scanner. Most non-commercial units don't have 18-20" platens, so in the past I've split a page from the book into two scan parts, requiring a reader to overlap them for full interpretation, a clumsy way to do it but certainly useful to someone who urgently needs the reference. Ideally the book should be commercially scanned, but again it is a large book in number of pages, not just physical size; it likely would not be an inexpensive enterprise.
A compromise solution is to use my iPad and a scan app, which I have a couple of, to essentially scan in a full length photograph, a technique Tim Bentley suggested. Such apps can auto-adjust to clip out surrounding background, since you have to be a good distance away to fit the long document in the screen, and ultimately produce only the document's image, and make it a PDF. That wasn't so simple either, due to the limitations of lenses on touchpad devices, and once again, attaining appropriate lighting. I've tried the technique with several other projects too, and sometimes the results are okay for the intended use, but usually I'm not happy with the resolution.
What I think I'll do when time allows is scan, as mentioned, each page in two sections. Then I'll try using panographics software to overlap and reunite the two images into one, but now finally in digital format. It'll take awhile to do that about 40 times. But then I'll be able to send it to Tim for the Coach Assist section.

Joel, I was planning on doing the picture thing also, but I'm just a dumb ole street cop! I can take a mean mugshot or get finger prints off a golf ball (kidding) but anything more complicated is beyond me. I'll try a few things to see if they work.

Have you looked at the club's members only coach assist section? It has wiring diagrams in 5 parts that says it is for 2003 Marquis, but actually contains diagrams for several years and models. I saw a 2003 Patriot and 1998 Marquis diagrams in Part 1. It may have what you are looking for.

Les,
The wiring for the basic/common circuits is pretty much the same across models. The diagrams Larry is referring to were very helpful to me when working on my 01 Contessa.

Joel had a great idea. I took pics of the schematics with my phone using a phone app. Sent them in a few ago.
-
Thanks all! I continue to diagnose.
I can't believe in all my years, I have not learned how to use a voltmeter. Yes, that sounds dumb, but I am a carpenter by trade and then management for the last 30 odd years and have always left the mechanical work on my vehicles to the professionals.
You see, I am a "Bleeder". All I have to do is look at a wrench and the skin just falls off my knuckles and the bleeding starts LOL!
If these damn RVs were made of all wood, I could fix them in my sleep!
-
I learned a new trick...if it works. Here is a link to the schematics to my 2003 Patriot Thunder Lexington. Hope it works!

It's not workin' for me, Jerry. At least not on my iPad. The link tries to connect but freezes and befouls the Forum site. I tried it several times, but have to back up to or restart the Forum just to get back to square one.
Joel

Joel,
Might be your iPad link. I was able to access from my PC w/no issues. It's a huge file (86 pages) so takes about 30 sec to download.
Steve

It took a lot longer than 30 seconds, but it finally appeared when using my laptop. Nice job, Jerry. I'm sure many members will appreciate access to it.

Jerry,
I have Adobe software and I was able to Optimize the file and rotate the pages so that each page has the title description on the lower right. The document is now 35MB instead of 98MB and is much easier to flip through the pages.

I started scanning and breaking my wiring diagram manual down into smaller more manageable files by drawing number. I have to reassemble all the scanned files, hope to have that project done this weekend and I'll try to figure out how to post them when finished. I believe my manual is the same as Jerry Emerts, the individual files will be much smaller.
