As promised, here's a photo of the 12v electrical
set-up in the front driver side storage cubby.
Since there was no connection between the car battery
and trailer inside 12v lights
, the electrician simply cut the black and white wires coming in from the six wires in the trailer hookup. All 12v lights and charging ports inside the trailer (plus the porch light) are powered from the deep-cycle battery
on the tongue only.
I feel a small sense of pride in that after the electrician left, I thought I should test the running/brake/turning lights on the trailer and found they didn't work. I'd read enough about 12v wiring to figure that he hadn't reconnected the ground/white wire. I checked with him and he said yep he forgot, so gave me basic instructions on how and where to reconnect. Mission accomplished. Pat myself on the back.
I also bought and mounted a Coleman waterproof box to hold the solar panel
controller on the tongue next to the battery
. The box came clear, but I spray-painted it silver to hide its contents. Drilled holes in either side of the box and used rubber grommets to seal/protect the wiring to battery and to 50w solar panel
. Bought a two-prong hookup and wired the panel/controller so I could just plug and play the panel to the controller. I thought 10 feet of wiring would be plenty long, but I'm thinking longer would have been better.
Had earlier made an adjustable stand for the solar panel
from aluminum angle. The guy at Perham Steel even cut the angle to the lengths that I needed. Saved me a lot of work and headache.
Also bought 1000 denier coated nylon backpack material from my favorite online supplier Rockywoods Outdoor Fabrics
to sew a carrying case for the solar
panel. Since the aluminum angle had some sharp corners, I padded them with 1/2" pipe insulation.
I find that when I've plugged in the solar
panel, the controller "charged" light has never come on. Does it take a long, long time (like all day) for the panel to fully charge the battery?
Also eliminated the extra lengths of wiring that a previous owner had hooked into the trailer plug wiring. Things look much neater on the trailer tongue now.
