Have you pulled the battery and taken it in to have it load tested? thinking this because when you say it is on the maintainer you get the flashing/clicking noises. Or if you have a real charger +10 amps or more try hooking that up and see if you get the lights to work......my 2 cents
I did find that the ground circuit the maintainer lead is on has 7.38 volts flowing through it. It grounds to the #2 ground location. I dont know where that is on the bike, not sure where to find that information. That appears to be a good starting place though.

I recommend removing the BCM to inspect the pins and sockets to ensure they're all making good contact, and no pins appear burnt.
Reseating connectors is always a good idea when troubleshooting electrical things.

I disconnected the BCM this morning and the ground on the maintainer lead was still hot at 7.38 volts. This makes me believe that ground #2 is not making a good connection. The other question is what is feeding power into the system that needs to be grounded if the ignition is off. The way I understand this is if the ground was making contact it shouldn't show any power because it would be going to ground.

Thanks for that Jake. I do have the service manual with the schematics, but that makes it a little easier to follow the the ground circuit.

If you or anyone else knows the location of the #2 ground on the bike, please let me know. I'm sure I can probably track it down, but it would be nice to be able to go to it easily.
