Hi Vince, always check the bulbs first for broken filaments. Then check the connection at the rear fender wiring harness, inspect for corroded, broken or loose pins. Use a dab of dielectric grease and repair as necessary. Check your brake relay if you have one , some models rear turn signals were single filament bulbs only, no running light. If all else fails get out your test light and start tracking the power wire from the harness connection.

SOURCE: need wire diagram for the turn signal switch.

your wires are crossed/shorting somewhere, probably in the headlight. remove the light to get to all the wires. you should be able to see which colors go to which side, also look at the wires coming from the turn signals both front and rear lefts will be same color and the rights will be another color. you should be able to tell by looking inside the switch which side is which color and which one is the feed to the switch

SOURCE: HD 89 FLSTC misfires using turn signals..

I definately would think it is something within the charging system. Here is a few tests you can run. First with the bike off take a multimeter in VDC check the battery voltage at the battery. (should be at 12.5 VDC) If not first charge the battery. Second start the bike, with it running and multimeter again in VDC check voltage at the battery while slowly opening the throttle(should see between 13.2 and 14.5 VDC at the battery) If you have more then 15 VDC then you have a bad voltage regulator. If you have less then battery voltage from the first test. You may have a bad stator and/or a bad voltage regulator. Third test with bike turned off and multimeter in continuity. Place one meter lead into either of the two holes for your stator lead(coming out of the front of the primary drive case) the other meter lead to any good ground. If you get a tone or continuity then you have a grounded stator, and it has to be replaced before proceding any further with charging system tests. If you do NOT have continuity then check the wires from the voltage regulator running back to the battery for any breaks or chaffing, if none are found. I would have the battery load tested as well. It also sounds like you could have a short in the turn signal wiring, maybe check the wiring inside the rear fender for chaffing as well. I personally think you'll find its an issue with the charging system itself though. Good luck and please let me know what you find out.

DeJevu! I thought I answered this already. Anyway, I'll do it again. The first thing I'd try is putting new bulbs in the turn signal lights. Use the proper bulb called for in the books. This is a pretty inexpensive test.

Next, you didn't say whether or not it was both sides or just one side that was not blinking. The turn signals are controlled by the turn signal cancelling unit. I'd try to find someone that had a known good unit that would allow me to try the unit to see if that fixed the problem. I say this because the units are expensive. The last one I replaced costs about $150.

Oh yeah, on the Softail, I think the "tilt switch" located in the speedometer is involved in cancelling the turn signals as well. If the switch is stuck in the closed position, it may be cancelling the turn signal as soon as you set it. The switch is not in the circuit for the four way flashers. You'd have to look at a schematic to tell for certain. Sorry, I don't have one for a Softail.

2011 Harley-Davidson FLSTC Heritage Softail Classic right turn signals and brake light not working


Hi, Pamela before testing any electrical component in the Turn Signal Circuit it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test because your battery may have 12.5 volts or more but little or zero amps causing the battery to be faulty and must be replaced, especially "AGM" batteries, also before diagnosing any turn signal/running light/parking light issue make sure the bulb is good and the light fuse has continuity with a test light. If you have replaced your OEM lights with one or all LED lights you are going to need a load equalizer.
If no turn signals work the cause could be a faulty turn signal module or the connector going to it, look for corroded, loose, or broken pins/sockets. Contact spray cleaner is great for removing corrosion.
If all four turn signals flash at the same time like hazard lights even though you only pressed one turn signal button then you have a LED light in the circuit and need a load equalizer that can be purchased from any motorcycle parts supplier.
If your speedometer does not function properly it will have to be fixed first because your turn signal module gets the data from the speedometer for normal turn signal function.
If your front turn signals don't work use a test light to check for power and ground at the bulb socket, then start backtracking the wiring through every wire connector to the turn signal switch/button and check for continuity, go all the way back to the fuse if necessary to find the cause of the malfunction.
If your rear turn signals don't work check your rear fender wiring harness connector first for corroded, broken, loose pins/sockets, power, and a good ground, the harness connector is usually located under the seat on the front of the rear fender then keep tracing the wiring look for obvious harness damage caused by the rear tire.
If you still can't find the malfunction backtrack from the rear fender wiring harness connector.
If one side does not work you could have a faulty turn signal switch or module check for continuity.

Before diagnosing any brake light issue always check the bulb and fuse first for integrity a brake light staying on is usually caused by the front brake light switch, which is mechanical, not disengaging. On early models moving the throttle control housing closer to the front brake master cylinder is the main fix. On late models, the switch gets tweaked and needs to be realigned. A brake light that does not come on when the brake lever is applied can be caused by a faulty switch or no continuity in the wiring at the switch. The rear brake light switch is hydraulic and it is extremely rare to malfunction in a closed circuit condition causing the brake light to stay on. Usually, rear brake light switch issues are caused by no brake pedal free play or a sticky rear master cylinder piston. A brake light that does not come on when the rear brake pedal is depressed can be caused by a faulty switch, air contamination in the brake line, or no continuity in the wiring at the switch.

My rear turn signals are not working. front turn signals work rear parking lights work brake lights work


In the diagram for rear lamp, the top wires are voltage, the bottom black wire is ground. The brown wire on either side should be tail lamps, goes hot when you turn on the headlamp switch. The other top wire on either should be for turn signal. With everything turned on, is there voltage on that wire?
Because the front works and the rear don't, possible wiring circuit problem? The voltage for turn signals comes from bcm. The bcm knows when you turn on turn signal switch, either side, then the bcm sends voltage to turn signal lamp at the rear and front.

Where is the brake light switch on a 2009 harley flstc


There are two.

The front switch is inside the right handlebar switch housing (START, RUN/OFF kill switch, RIGHT TURN SIGNAL) and operates off the front brake lever.
The usual problem with this is it either sticks, or the "tit" that works off the brake lever gets broken off, usually because the front master cylinder wasn\'t installed by the correct procedure.
Usual results is the brake light will not turn off with the ignition on.

The other switch is located along the rear brake hydraulic line.
Start at the master cylinder and follow the line back to the rear caliper, and you\'ll find it eventually.

It appears Harley has a problem with the rear brake light switch on this year, as it tends to spring a leak, brake pedal goes all the way down without stopping, sometimes smoking from the brake fluid being sprayed on hot engine parts, etc.

Front & Rear turn signal


Not familiar with the Softail Rocker, but the 2009 Baggers have a "Turn Signal Security Module" (TSSM) as one unit.
This is what it looks like:

Phase 7 install


Hi George, always check fuses and bulbs first, you could have a faulty turn signal module or a bad turn signal button/switch, remove it from the switch housing and check for continuity, check your wiring and connections from the turn signal switch to the turn signal module with a testlite. Make sure all wires are not worn or pinched and connector pins are not corroded, broken, or loose. For a free wiring diagram please visit the website below. Good luck and have nice day.

Engine shuts off with the use of turn signal


Is this the turn signal switch on the same grip as the engine kill switch? If so, carefully dismantle the switch block and look for a loose or broken wire causing a short.

1995 FLSTC Right Rear running light doesn't light up. Turn signal works fine, no power through running light circuit after mystery box on rear fender (below seat, in fron of fender). L side has power out...


The only "mystery box" that I can think of is the turn signal cancelling unit. It controls most of the lighting on your bike. The box is about an inch and a half wide by about three inches long, little over half an inch thick.
Disconnect the plug on the end of the box and check the pins to make sure they're clean. Also check for any sign of a short between the box and the light. I've seen people buy the box, and they ain't cheap, only to find out that they had a short somewhere in the wire. If you do have a short, the only thing you'll see is that the light won't work. It will not blow a fuse or anything like that. As far as I know, there is not way to test the output unless you've got a special plug made up to do so with. If you know someone that has one, swap the box out with a known good one. Last time I bought one of these boxes, it cost $150 and that was several years ago. Good Luck.
