Turn Signal Failure
Hi All,
1994 FLHTC
Was riding home from work yesterday and my turn signals stopped working. Headlights work (Hi and Lo), horn works, brake lights work, front turn signal bulbs illuminate properly as running lights.
I pulled the turn signal module and began following the test procedure in the service manual. Have power, have ground. Had to stop there because it was too late and I didn't have a jumper wire handy.
The test procedure says that if all tests pass, replace the module.
Assuming the rest of the tests pass, which seem to be more for eliminating one side or the other, is there anything else I should check before I pay for this module ($150, at least).
The only thing I can think of was that I hit a good sized bump on an off-ramp (unavoidable). Could that have jarred something loose at the rear? Would an issue with the rear signals (ground, blown bulb) cause all the blinkers to stop working?
Thanks in advance. I did quite a bit of searching on the forums last night, but I am hoping to have this fixed before the long weekend. Didn't get into the wiring diagrams yet.

Nick, I have already had one of those modules fail, although they were still readily available at the time. If yours has indeed failed I suggest you look at aftermarket alternatives, such as Badlands.

Hi, i had problems with the indicators on my bike, sometimes would not work on one side, then stopped working altogether, after checking everything i could, i bought a badlands flasher module, indicators now work fine, only difference is the self cancel function is a fixed time delay, it does not connect to the speedo, like the original, but so far all good

My replacement has been fine, probably for longer than the original one lasted. If your new one gives you similar service to the dead one, you should be OK for quite some time yet!

I was going to white enamel the inside of my blinker assemblies and get the badlands turn signal module as well so I could put in some LED's since they say it has a load balancer for them in it already.
Just FYI - MidUSA cycle parts has the modules in their catalogue - however the pictures of the items don't show them having the plugs on the ends of them, so you might have to buy the model off of fleabay to get that.

Been there done that brother. Check for shorts or bad power connections. Wire could be pinched somewhere or a bad ground. Took me a while to find it.

Put it all back together and have about 100 miles on it with no issues.
For future reference, the module can be accessed from the right side of the bike, no need to open the fairing. Part number is 68570-94B.
