Testing the Generator and Electrical System (Part 1)

We finished installing all the electrical system components (batteries, control panel, lights, outlets, and A/C) and it was time to test the system. So I fired up the generator and started checking each part of the system. I rigged up Hope's rain umbrella to cover the face controls of the generator during some on-again-off-again showers we were having. 
As you can imagine from the title of the post, I found some new opportunities for troubleshooting--the AC system was not working correctly. Only the DC system was working (pulling from the battery array inside).
