Battery is new, kinda what started this whole issue, battery dies, put in new battery, lights quit working. Fix lights by installing a bypass switch, until new J box arrives. A week later, regulator explodes. Replace regulator, computer, j box, and all fuses by battery, turn key and nothing, dash doesn't light up, nothing. Only thing that works is the turn signal, so at least I know there is power out of the battery. Gotta be a ignition relay or something I fried somewhere. Bike is in neutral, tried it with and without the Power Commander and nothing. Checked battery, it tests fine. Completely lost. I know a bad switch would cause it not to start when I hit the go button, but I'm not even to that point, as it seem the power isn't even getting to the bike.

Nothing should be this fast.

bypass the ignition switch i bet its toast here is a pic of the wires and how to connect them
make jumpers using spade connectors and connect the wire colors as shown this pic shows the ignition side wire colors so
make sure each color lines up with corresponding color on other side of connector

If the ignition switch is bad will it keep the bike from even turning on when I turn the key? Definitely gunna try this.

Still can't track down the issue, will likely be taking it to a shop as soon as I can get or borrow a trailer. Going to try a few more things then will be giving up. Stroke of luck though, traded my Warrior for a ZX10R so at least I can still ride.

Looking at the schematic, all power goes thru the Main 30A fuse. The one by the battery. One feed goes to the turn signals, another to the ECU, and the third feed off the Main 30A fuse goes into the Junction Box. You need to verify you have 12v at all 3 of these locations. The .pdf is kinda shitty when it comes to wire identification.

Looks like at the Junction Box it's a Y/R possibly, which is the same color coming from the Main 30A.

The second wire off the Main 30A is BK/Y maybe, which remains the same color tapping several items, but notably your Front and Rear Blinkers. Your Fuel Pump, Fuel Level Sensor, Left Handlebar Switches, Headlight Relays (Low and Hi), and your Meter Assembly (guages) all run off this second feed. There are a couple grounds on this feed as well. One goes back to battery ground, other to frame ground.

The third wire off the Main 30A looks like it might be Y (or R). This one feeds your ECU, Regulator/Rectifier, Junction Box, Meter Assembly (guages), and Ignition Switch, where it branches in with both original color and Y/BK maybe after the plug (same color prior to the plug)

Since you have blinkers, I would assume you have both ignition and 12 past the Main 30A. There are several diodes in the path inside that Junction Box (I think there are some in the battery tray as well, don't remember) that could be bad. You need to trace all of these connections and find where you are losing power, and this will be your issue. Test before and after each component and when you don't have an after, there be your issue. If you can read a schematic, it will make more sense to you most likely than this explanation... Trace the wires my man. You'll find the fault then. You ain't getting power to your cluster, and maybe not to the ECU either. It is getting to the ignition switch, and past it, because the blinkers work. Narrows it down a bit.
