Spring 2018 started to show itself a bit a week or two ago. I decided to get into some wiring and also made my final decision on building a tongue box rather than buying one. The motivation was that I could customize the size to fit my needs. It'll be large enough to house the deep cycle battery and a full size propane tank. I'm not sure yet if I'll run a full size propane tank regularly, but perhaps for longer trips.
Above, I'm cutting chunks of 3/4" plywood for the tongue box. The temperature was finally in the 50s again finally. Immediately the next day we had about 4 inches of show. Such is the new Spring here in Pennsylvania.
I've now mounted key elements of the wiring blocks in the raceway. Below, from left to right: busbar, ground-bar and fuse block.
The photo below is just a higher elevation view of the wiring raceway to provide a different angle. I have to break now to establish a milestone. Up to this point, the cabin lights and fan have been sitting quietly in place with the their wiring running through the ceiling and dangling into the raceway. I've finally terminated all that onto the fuse and ground blocks. The wiring from the tongue to the raceway is now also in place and connected.
With drums rolling, I set the battery on the tongue, popped in my fuses and flicked the switch on the main fuse...
We have power!
Ok, it's a minor accomplishment, but a good sanity check to ensure I didn't drive a screw through a wire somewhere up there. Below, I have two photos of all four cabin lights in all their glory.
I have the battery resting below with temporary connections, waiting until I have the tongue box built up. In the lower left of the photo you see the 20 amp fuse on the positive terminal side.
Below, I have a more focused view of the electrical raceway. On the left is the main busbar with the positive feed from the battery. The busbar breaks off at the top into the fan and two light feeds into the fuse block on the right. The middle block is the main ground. I'll post explicit wiring diagrams in a later post. I mean really explicit, NSFW (not safe for wiring more likely).
I've also tested the fan wiring, which you can see temporarily wired up in a few of the previous photos Final wiring for the fan will occur after painting and trim work. It was certainly a milestone to see the internal wiring operational.
I'll move on to the tongue box this week with a really nice battery mounting situation in mind, along with storage.
