Dead Electronics but will crank on bypass

Hello! I purchased an 03 Nomad 1500 Fi last summer and it's been a great bike and great to ride. At the beginning of this season I was having issues with the fuel pump not priming, so I pulled the battery, got it tested, and was told it needed replaced. I bought a brand new battery and still had the same problem. After lurking through the forums and reading posts of similar issues, I tried pulling the tank and replacing the fuel pump filter and cleaning the assembly. Sure enough the fuel pump primed right up and it has been running strong ever since.

Fast forward a month and I have a new problem- it's dead. I rode it to work in the morning, it started right up without hesitation, made the 25 mile trip no problems, and parked it for the day. Came out to leave work and I have no electronics whatsoever. No head/tail lights, no indicator lights on the speedo, no horn. Nothing. Thinking maybe the battery died, I called for a jump. We hooked the jumper pack up to the battery, still no power to ANYTHING. We make sure all the connections are tight, make sure they're clean and not corroded. Still no power. Then we decide to hook the jumper pack up to the started and ground it to the frame, as soon as we do the starter begins to crank like normal, but without fuel in the pump there's nothing to fire.

Finally I got it towed home, pulled the battery out and checked it with a multimeter, 12.82volts. Battery is good. At this point I'm thinking there is a short or a loose connection, but I have no idea where to start testing to try and figure it out.

The tow truck guy said maybe the ignition switch was somehow messed up and was acting like the key wasn't in/turned on, so I think I can check that, but any other input would be appreciated!

Did you check the main fuse on top of the starter relay?

The 30a fuse located near the positive terminal of the battery? Visually yes (did it while sitting in the parking lot) it looked good.

Did you check it with your ohm meter?

Checked it tonight with the Ohm meter, tested as it should.
Just out of curiosity I checked what would happen to the battery when the key was turned, no change in voltage.

First test:

1. On starter solenoid, push red meter lead down beside white wire to contact pin.
2. Black meter lead to battery ground.
3. Take voltage reading.

Post back with reading.

1. Locate junction (fuse) box.
2. Push red meter lead down beside any one of the brown wires.
3. Key on, take reading.

Both solid brown wires toggled between 0V and .01V with key on, B/W wire (not sure if it makes a difference) had 12.93V with key on and off

It's a long shot, but on the left side of the bike, coming off of the ignition switch is a pigtail with 5 wires. Goes up under the fuel tank. It plugs into the main harness. Check to insure it is plugged in and tight.
