Hey guys,  I have a problem. And it's not just with drink. 

I've torn my hair out this weekend over this so any help is appreciated.
The bike is a 2008 Sportster. 

I've recently changed my front indicators / bars so that may have something to do with the issue. I've also changed the tank too, but re-fit the stock EFI.
I cut the stock blinkers off, and wired in some Moto Gadget bars end indicators, using the Badlands 3 in the line to load equalise. 
I wired them all in, refit the bars and some new grips, turned on the ignition, hit 'run' and this is what I get.

– Fuel pump primes
– Headlight on, full beam works
– Horn works
– Speedo does nothing at all - no lights etc
– No indicators work, front or back
– Rear light worked first time, now it doesnt. 

I also relocated the ECM to behind the rear cylinder, as most people do when they need a new rear wheel guard.

All fuses have been tested (by eye, I don't know anything about testing them properly).
Unfortunately it's still up on a bench on a stand so I cant see if it starts as it will probably fall off. 

I'm SO close to having the bike finished and out on the road, and now this has cost me a whole weekend of work.

Any help would be appreciated. 

I would get a cheap multimeter (a $20 one would do the trick) and then use that to:
- ensure the fuses are okay
- check for shorts somewhere - most likely in the handlebar area (as that sounds like the most obvious problem)

Does the bike start?

Problem solved.

Turns out the LED turn signals on the front were 'secretly' already 12V, so the addition of a Badlands load equalizer was fucking the whole thing.

Wired all stock parts back in, worked fine... Went piece by piece adding the after market bits until I discovered what caused it.
Long (ish) process, but saved a stint at the stealership.

Thanks for your input though, both.

good result and a great way to track down the issue!
