Time for another update!!!
Thanks to dwh, we now have fully grounded switches in our cab! Please note that you can't run the switch power off a Duracell battery - that is for illustrational porpoises only!
I caught an error myself - remember to use the same gauge wire for ground that you use for power! I had the diagram with 4GA ground in the 'high-current' circuit...not a great idea! It's been upgraded to 2GA
Making the system modular on the cheap
So, you want to make it so you can quickly disconnect your solar panel? Easy! Use a weatherpack connector!
Get them from our friendly Amazon tribe HERE - you only need a 2-pin connector. Just wire it in between the charge controller and the battery. Then, when you want to disconnect your solar circuit, just unplug the connector! (note: to prevent risk of fire or explosion, disconnect the sun from your circuit before unplugging the weatherpack connector).
Addendum: If you want to leave the charge controller plugged into your battery and just disconnect the panel, you can do this by moving the weatherpack connector between the panel and the controller. See how easy, cheap and flexible this is????
So you went right out and wired up your trailer based on the first diagram and now you are wondering how to disconnect your trailer? Yes, I forgot trailer disconnects!
Easily fixed! Go HERE and buy part number SB50. Then just wire this into your 4GA wire where it shows in the new diagram (the connector is for 6GA, but you can shove the wire into the connector and using the smaller connector is important for...). While you are at it, order a few extra connectors of the same size (we'll need them later on in this thread, trust me)
Here's the new diagram!
- Added ground for switch and illustrated power source in dash
- Updated ground wire in high-current circuit to 2GA
- Added connectors to both solar and trailer circuits
- Changed main power lines to red to make it easier to see
