No power to headlight
Put a set of bars on my 10' Street Glide. I have everything else working and bike runs, etc... but I have lost power to headlight somehow? There is no power to the plug. There is power to the auxillary light plug up there. The fuse is good. Any idea what path it takes to fire the light? Im stumped.

don't know what year you have. ( recent models use a bus system which is more complicated):
Blue is commonly used by HD for the wire which carries power from the headlight fuse to the left handlebar switch, this circuit runs through a couple of connectors on it's way.
so check power at the fuse with a trouble light and move toward the switch.
guesses are: open circuit inside the bars ( your new wiring), or shorted...in which case the fuse would be blowed.
for trouble shooting a trouble light can be better than a meter as a trouble light places a load on the circuit.
a meter may show voltage that looks correct, but the power doesn;t have enough current to do anything.

Power at fuse both sides. No power at handlebar switch. Its 2010. Also no wires were cut or extended. Just removed pins from plug and routed inside bars. I have double and triple checked that part. I do not think I have power making it up to that plug for bars but not sure what color wires on bike side of plug to check.

When you pull a pin or socket, many times to push the retaining tab down so it no longer stays in place. Which means sometimes when you plug the two connectors together, the one pin/socket gets pushed right out the back. So look at the backside of the connectors for a pin/socket sticking out a little bit.

I am having the exact same problem as of today. I did extend my wires though. But I know the solder joints are okay. When I pulled my wires through the left side was actually quite easy with not much force on the wire at all. Please let me know what you find and I will do the same as I am pulling my hair out over this.

you'll just have to go through methodically.
start with the suggestions I gave earlier in this thread- do you have power to the switch?
if not, first check the fuse- if ok, follow the power from the switch back thru the harness to the fuse to find the fault
btw- soldered joints do not hold up well on bikes, it may be months or years, but the wire strands will break due to vibration right where the tinning ends.
