You can see it in this shot, similar looking but a lever switch inside the drawer... the big red one is the Chassis battery cutoff.


And on the subject of HWH Levelers, my pump and reservious is located in front of the radiator...
And front leveler mounts, if you have not seen the mess I inherited, here was mine.... I cut them off as they were dangerous AND UGLY!



For those who might know the difference, here is my MH cruising, and you can hear the Flexfan noise...
Click on this pic to watch video.


No MH work today...my Individual insurance clients been calling all day!
But I did get my 80' of silicon hose... sadly, I mistakenly ordered 3/4 instead of 5/8...

After seeing Steve's back of the battery tray, I want to take shot at his odd front solenoid:
His rig appears to have the "battery combining relay" right above his shutoff switch on the back of the battery tray.
Soo, why would there be another one in the front?
My wild guess is the Levelers. This may have been their first version of trying to incorporate a leveling system or it was installed after the fact. To avoid draining the Motor battery, they installed this relay to combine all batteries for the HWH operation.
If that would turn out to be true, Steve could route that trouble, burned wire directly to the BAT+ at the battery drawer and eliminate that terrible routing.

Ah... I wondered what that was....
My Leveling system works on the motor battery alone tho... I had the house batteries out when I was lifting the rear for the gas tank refurb... But maybe it only saw the chassis battery and that was fine..
My motorhome is weird all around, even from the factory. Having just finished reading your 310 jacket thread, I think you would appreciate some of its odd features... The factory curbside dinette instead of barrel chairs!
Now the Obamacare deadline is behind us, I will be back at the MH today, and will sketch out the wiring layout as best I can.

Love the curbside dinette. Adds storage and great day use. Barrel chairs and wimpy table are waste of precious space to me.
Please check if you have a switch in your glove compartment, if you do it energizes the back solenoid. Do your levelers work with the ignition off?

Not sure what you mean. I have the solenoid that combines the coach and engine batteries attached to the back of the battery box, also have the battery disconnect switch fastened to the back of the battery box. There is a solenoid that is fastened to the bracket that is located above the top of the engine near the front to which the cruise control vacuum module is also fastened. I have not followed those wires to see what it controls.

Peter,
My levelers only work with the ignition on. I do/did have a red plastic toggle switch in my glovebox, but it is broken and floppy... It does not appear to be connected to anything... But the electrical part behind may have fallen off, and into oblivion behind the dash! I wondered what that was. So what should it do?
I also have a momentary switch next to my ignition that I think boosts my starter battery by connecting the house too.
Will get pics later today.
Gunner, I have a solenoid on the engine bracket next to the cruise control unit. I am trying to understand the rest of this puzzle too!

I believe bkahler advised that the solenoid is for the starter circuit.

Steve, since you need to concentrate on other issues besides this wiring puzzle, i would do this:
1. Dont use the levelers
2. Leave the burned cable out for now, so you can finish your heatshield/header
3. make sure your engine battery has a full charge for starting
4. Avoid using any of the start assist switches

In the worse case scenario, you would have to connect that cable that was burned to Bat + directly, because that is where it currently is via the starter terminal (please confirm that it was connected to the Bat + terminal on the starter)

Peter, you ROCK.

That phone conversation clarified my mind, and got me on track!
Peter gave me a list of things to check and verify, and I went at it.

Starting from the source... the battery tray.
Here is how my setup looks.



Now, starting from the left(fwd), that is the "Combining solenoid", and the two thick red wires come from the Motor(LH) AND House Battery(RH).
Note the Black cable(#1) connected to the LH terminal. More of that in a bit...

Next item to the right is the House battery disconnect switch.
Note the smaller red wire connecting the RH of the combiner solenoid to the disconnect switch..
Is that too small gauge?

Note the HUGE(5/16 or 3/4 dia) Red cable on the RH side... that is the one I pulled and rerouted and takes House battery power to the relay/solenoid in the driver firewall.

The Black cable(#1) from the LH side of the combining solenoid goes fwd to...
This junction box... on the chassis rail.



From this box, is the black power cable(#2 that is removed) that goes to the starter. This is the main starter cable.

Now I started at the front firewall solenoid.
Red cable on the RH side is from House battery.



Now, on the LH side of that solenoid...
Thick Black cable with ribbed grey cover pointing UP went to starter lug(the cable that was melted).
Black cable with ribbed grey cover pointing DOWN is MAIN ALTERNATOR feed/power/charge cable.
Black cable behind this one pointing down, is main power feed for HWH Leveler pump.

Note, the Alternator power cable is pretty beefy..
In this pic I am comparing a 10 Gauge cable to the alternator feed/power cable!


My guess is it is about 2 gauge!

The end result, was I moved the melted cable from the starter lug, to the junction box connector, it reached just fine.
This meant i did not have to put 2 thick cables on the starter, and so that is back in and good.
The starter shield is good, and I added some serious heat shield material for added protection.
View from under...


Will tidy up tomorrow and hopefully start her up!

Why all the hassle?

When I look at my dash indicator lights and see one that warns me that the washer fluid is low, I wonder if there are simply way too many frills designed into these coaches. The "battery combining" feature with all it's switches and relays is an awful lot of fuss to do the job of the set of jumper cables that we're
all carrying around anyway.

you know the answer to that trivia question. After spending 100k plus for the shiny Motorhome instead of the the Lakeside cottage, the wife wanted, there is not another 19.99 for jumper cables. Besides the dirty hands factor and advanced technical knowledge requirements ( hmmm was it red to black or black to red???)
