Ok, I've scoured the site looking for troubleshooting and sure enough I'm not finding anything too substantial so I thought I'd post here to see if anyone else has had similar circumstances.

06 speedmaster, got the light kit with the bike (given that I would install it). Took the bike apart, installed the relay, hooked up the harness to the loom plug, fed the wires through the bar itself, out to the actual lights, hooked up the clips, crimped them on just to make sure they were connected, turn the bike on, flipped the switch and sure enough nothing.

now here are the details so you know the testing conditions. currently the tank is still off the bike, everything else is still on it, I heard clicking from the relay and I swaped it out with the other identical relay already in the bike, and nothing changed. The fuses were caked in white as was the block. i took a brush and cleaned the block out and the fuses and there was no change. both bulbs look fine, the filaments are still intact and all the fuses are intact as well, despite their white coating they had.

I'm at a complete loss for what to do or how to fix this.
I'm going to try to replace the bulbs themselves tomorrow and get new fuses for the whole bike, but other than that I'm absolutely baffled as to what the issue is.

Anyone have any insight?

Have you actually replaced the fuse? Sometimes you can't actually see the problem within the bad fuse. I would also start checking the wires with a test light.

Bypass the relays and wiring and go direct from battery to the lights with a test lead. You said you hear the relay clicking. Are you getting power on the other side of the relay?

another day of testing, and I don't feel much closer to an answer.
So I hooked a test lead up from the battery to the actual lights and they do turn on, so at least i know the bulbs aren't dead. with everything wired up I'm only getting about 8.2 V DC at the blue/white wire in the light assemblies, which leads me to believe there's a grounding issue, most likely somewhere around the relay.

I've also now replaced every single fuse, cleaned all the connections with electonics cleaner and coated everything in dielectric (sp) grease. still to no avail.

I guess my next question is, is there any type of troubleshooting from here, as i'm assuming there's a bad ground somewhere, i just don't know how to find it/what to do when i do find it

Check the ground by doing a voltage drop test. Set your meter for DC volts then put the black lead on the negative battery post and the red lead on the ground lead at the bulb. Turn the lights on and you should see less than 1VDC. If you see a lot more you have a bad ground issue. You may have a bad relay too. You probably can get one at your local auto parts store.
