Turn signal problems
Hi all. I am new to the Forum and need some help. I have a problem with my turn signals. I have seen other posts related to turn signals, but nothing that matches my problems. So here is the problem:
-My front turn signal lights stay on whenever the ignition is on.
-My rear turn signals don't light up at all.
-There is no response from the turn signal controls at all.
The bike is a 2012 Road King and pretty much factory. I have not changed the lights to LED or anything like that. Anyone have any suggestions? Anything would help. Thanks.

Front stay on dimly? That would be the marker lights on domestic models. Do you have any codes? Check your connection to the TSM/HFSM and verify that it is connected, you can also to the code check to see if the TSM/HFSM is responding as well, by setting RUN/STOP switch to RUN, hold TRIP switch, turn ignition switch to IGN and wait for speedo to sweep. Once speedo sweeps release,trip and DIAG should appear momentarily in the odometer, replaced by PSSPT, short press trip until the first S is blinking and then hold trip until you see a change. If you see NO RSP you have an issue with wiring or with the TSM/HFSM. Otherwise you will either see codes or CLEAR.

Do the 4 way flashers work? Also, check the "Accessory" 15A fuse.
I think that if your 4 way flashers all work, that would confirm the the bulbs are good. The turn signals should be powered thru the Accessory fuse. The power to the turn signal switches should be an Orange/White stripe wire.

I have not tried the 4 ways, so I will do that. I checked all the fuses and all check good on my tester. I crashed the bike this past September and had to remove, straighten and paint a few things (all on the front). I had to remove the auxiliary light bar and the housings to straighten things up. But I hooked everything back up the way it was (to the best of my knowledge.....I took a ton of pics during take down). I did remove the light bulbs in the turn signal housing, but they can only go back in one way (the pins on the bulbs are staggered). The bike is a 2012 Road King.

Right, they are supposed to go in only 1 way but the sockets can allow the bulbs to be installed upside down, lights on the front lit bright with ignition on would be a symptom of this issue. Try 4 ways and check for codes as was described earlier.

Right but how many times has someone tried to get the bulb in only to force it into the socket and bend the socket slightly allowing the blades of the bulb to make contact but not be fully secure. I have seen at least 15 occasions on this message board where that was the case. It happens all the time, the socket is just really thin metal that will bend easily due to the slots on both sides. It is a simple check that takes what 2 minutes on a road king and that is undoing both screws on each light if you have the flat lamps and less than that if you have the bullets. It may. It may have been a PO who did it initially and then corrected themselves when they realized their mistake but it allows for future mistakes.

I`ve seen these bulbs installed wrong several times, although I was surprised the glass on the bulb didn`t break when they were forced in.
