I had issues like that. THe Rad bars are very rough inside the bar. You probably have an exposed wire or two. I would re solder and rerun the wires. I would check the connections prior to running the wires internally then check them again after you have run them through the bars. No Fun

 

Did you do anything else to the bike at the time you were doing the bars?
If not, then you need to may need to pull the whole handlebar wiring job apart. I know it sounds like a nightmare but that's exactly what happened to me. Look at the electical schematic and see if you can figure out which wire is probably shorting out by comparing it the electronics that aren't working right.
Mine was a popping fuse whenever I used the right turn signal. Turns out one of the wires had lost it's insulation while being pulled through the handlebar and was shorting against the inside of the handlebar. That's when I switched to 20 ga. so the wires would fit easier. I ended up doing the whole job over again.
Giant pain but you want to get it right. Has been working fine ever since.

 

One additional thought. Check your fuses. If one has blown, the electrical schematic may give you a heads up as to which wires to be looking at.
Good luck.

 

didnt see any blown fuses, but i will check again.

 

After I had installed the BAK I had an engine light issue and loud clicking upon attempted starting, as if the battery was dead. Sometimes it would start, sometimes it wouldn't. I had forgotten to torque down the ground from the battery to the frame. Could be that you have an exposed wire somewhere in the handlebars grounding out.

Good luck...

 

negative pst on battery was loose...i torqued it down, and bike runs fine, but indicator light is still on...gotta be a wire grounded somewhere.
