I started on this day with finishing the top sections. Here, where the wires come into the galley overhead cabinet - they branch into the cabinet, or into the archway. Through the archway are the long installed fan BK and W lines, and the new main runs of the interior under cabinet light's B and W lines. You can see a couple of small wire tap clips in the cabinet section for the galley light's B and W lines.
Also note in the above photo, the coil of wire in the cabinet face round hole. That is power R, ground W, and two speaker pairs for the round marine-style stereo, which will fill the original hole vacated by an in-your-face 110 Volt light fixture, that was really, really ugly.
Above that hole, I might put a round "weather station", or something else as yet undetermined, that fills the space better and tries to match the look of the stereo.
Back inside the cabinet, here's a close up of the wire taps and the bundled wiring harness.
Stepping back, you can see where the galley under cabinet light lines run and are stapled down tight (other clamps and staples are left a bit loose for wire movement as per code at least on the 120 Volt). I still may design some sort of protective cover over the exposed wires here and on the other side.
Here we continue over the archway to the dinette side. The archway incidentally is ready to be enclosed. The wood panel cover is finished, but I think I still need to steel-wool cleanup the original plastic edge trim. I'll install that one day when the mood hits me so look for it future pictures.
The main B and W lines run to the far end of the cabinet and out a new drilled hole for the bed chamber light. Just behind the propane line are two more tap clips for the two short lines that run down and are stapled to the cabinet floor, exiting out a new drilled hole for the dinette light.
All finished up here, I moved lower, and started with the tail/signal/brake lines. On the right, both of my remaining longest lengths of brown and green wires were simply a few feet short of the total length I needed for an unbroken run! What to do?
After careful checks, I determined the lengths would work if I put a break in the fresh water tank cabinet, at the curve of the wire harnesses.
Putting a break there was something I had sort of planned on doing anyway, for removal process of the water tank in future without having to pull wires back though too many holes or runs. So I used bullet connectors in that spot on those two lines to complete the circuits (I'll show those towards the end of this post), and I'll plan on cutting wires there and adding more bullet connectors on the remaining lines, in the future - if and when needed.
So I began the longer lengths of the two wires in the back. But before I could do that, I had to determine and drill wire access holes to the tail lights. Here's what I have, replicas of the traditional "wedding cake" style lights, picked up a long time ago from Vintage Trailer Supply.
The mounting holes were almost exact to the holes on the sheet metal. So close in fact, I could have simply put them up and screwed them down without measurement - just the way the were originally done. Yes, it seems the original installer slapped these on without measurement in the same way they had done with the clearance lights, and the front cab-over window placement, and just about everything else on the little camper.
But you know me. I broke out the ruler and tried to see how I could mount the lights symmetrically to one another, and still cover all the holes. It was so close (they were off-set from each other enough) that I actually had to cut a little lower template (third hand) to hold the height at the correct 1/4" increment from the bottom, while I measured from edges and scribed my marks. Verify safety on the opposite side, drill hole...
And presto! We have wire!
Next I pulled out the propane tank divider board and cut wire channels, deep enough for the wire run including retainer clips.
And chiseled a groove on the back wall for a wire channel.
Where the wiring exits the compartment on the right, it drops down through a drilled hole through the wing 2x2 and on the inside elbow of the grey-water bathroom drain-pipe, into the electrical cabinet under the dinette seat. That bit of exposure on the inside elbow, is the only exterior exposed wiring on the camper!
And with the tank divider board back in place, the wire is completely protected except the short visible segment safely tucked into the wall board. I might smear some caulking over that.
Over on the left side now. I had started to run those wires closer to the face of the cabinet. But after doing the right side, I changed my mind and pushed the wire run to the back of the cabinet, out of the way, and protected in much the same way. Drilling a new hole, I pulled the run and I stapled it down.
Then simply spaced the water heater cradle a fraction of an inch inboard.
Having already pencil marked it at this position, I ran the screws up into it from beneath. Remember, this is back ago when it was designed to offer strength to the wing board seam (the wing is slightly longer than 8'). The cradle spans the seam, and I used 9 screws for that strengthening reason, much the same as the propane tank divider board functions on the starboard side.
This little bathroom cabinet is so small, it will probably not fit our shaving kit/bathroom bags after all. I foresee it storing rolls of TP, and the removable hand-held shower head and curtain, both in a little storage bag of sorts. The wire runs on the surface of the back area.
And presto! Wire!
Back inside I connected the water heater and coiled the excess wire (for easier future manipulation) where I'll zip-tie it out of the way, to the propane line once installed.
Here you see the ignitor control box mounted high, away from any potential water leaks or drips that might occur and harm it if it were mounted low.
And the left, rear wiring run as it passes by the range.
Then it was a matter of small adjustments on wire runs and making connections in the electrical cabinet and fresh water tank cabinet - switches and speakers, placing wire-ties and clamps, and connecting the water pump, running short ground wires from grounding bus-bars to the water heater fail lamp, the water pump, and the voltage meter by the power center. This was the fun part! Making it all come together!
One trip back over to the auto parts store for two 8' runs of 10 AWG R and one 8' run of 10 AWG BK, and I was back at it.
I left a little slack at the water pump too and coiled it once over the pump.
I gave the battery lines a little excess, so as to reach a test battery sitting out in the room. The extra lengths can be tucked inside a battery box under normal circumstances. This photo also shows the vehicle connection harness laying up on top of the cabinet for later completion, after placement of the battery box and vent, and the fresh water line in this region.
Here's where the harness curves at the fresh water tank cabinet, and where the bullet connectors live.
Then continuing toward the power center in the electrical cabinet, here's the backside of the battery shut-off and water pump/heater switches.
The double mount is the new water heater switch and lamp. The single is the used - from my 1995 Skamper parts camper. The single is a bit loose and I've tried to tighten it up, but it remains uncooperative. It is printed for ON up and OFF down. The new Suburban switch is opposite (printing on the mounting plate) - odd.
I think what I'll do to make the printing agree with same ON/OFF direction, as well as replace the loose fitting single switch and add visual convenience to whether the circuit is on or off, is replace both switch portions with lighted amber types, with down as ON. Also, I don't think I like the fat blade connectors I used on the switches. I'll probably replace those with the same type you see on the speaker.
The two heavy (10 AWG) BK grounds go: one to the battery negative, and the other to the vehicle connector ground. The three heavy (10 AWG) R lines go (from one switch terminal) to the power center and the other to the vehicle connector battery terminal, and (from the other switch terminal) to the battery positive.
The harness continues through the dinette floor. This picture got wonky and I failed to fix it. You get the idea.
And finally into the electrical cabinet. Note the speaker connection, the brown and green run for the tail/signal/brake light, the ground connections, the volt meter lines, and the power center circuit lines connected. Pay no attention to the Power Inverter in the room. All in all, a nice clean install. I like it!
Now before I connected the battery, I completed both a visual check of the system, and then a complete multi-meter check of all circuits for shorts and opens.
Then I connected the battery and began voltage checks at terminals and began operating switches and installing fuses for the individual circuits. It all checked good and here's the face of the system.
For now, I'm using 5 Amp fuses on the 7.5 Amp circuits, because that's what I had. I'm interested in testing the loads and then moving up to a 7.5 Amp on those if I need (or just as a matter of course). I think, based on my bulb and fan math, I may need to up the one circuit, but the other two may set fine at below five. But that's more curiosity than anything else.
Today I think I'll install light fixtures. Then I can start using battery, and thereafter test the charger.
Earlier there was some discussion about this charger not being up to the task. It had a bad reputation for losing a portion of it's charge ability/process. Apparently, that was due to a battery reverse polarity upon connection problem. Since the time of that circumstance in this brand, the manufacturer has added a 40 amp reverse polarity protection circuit (bottom fuse in the pictures). That may protect this model charger from suffering the same condition of previous WFCO models. I hope so. We'll see. I also bought a 2006 Dodge automatic transmission. Previous autos in Dodge sucked. They changed it. Mine has been a power house! Reputations can be hard to shake!
