Default aftermarket turn signal self cancel, 87 Heritage

Hello all, I'm new here and new to HD. Just bought an 87 Heritage, love the bike but hate the turn signals. I did a search here but haven't seen this posed. I bought a SDC Back Off self cancel module, fitment seems good for the bike. I read the schematic, opened up the spedo panel, found the flasher, but can't see a spot where all the wires come together to wire the new module in. Has anyone else installed one of these on an 87 Heritage or similar that could give me some tips as to where to tie this in?

I don,t know what the instructions are telling you. My 87 Heritage still has the blinkers with the push and hold buttons. Under the dash about all you will find is the breakers for the electrical system. four of them mounted to a rubber strip attached to the dash base. If you look on the RH side of the backbone, beside the ing switch, you will see all the wires that run from the switch to 4- connecters under the backbone.

I think if you had the RH side gas tank off, you could see everything pretty easy. The row of 4-connecters is much more visable that way. The two most forward are going up tp all the control buttons on the handle bars.

The instructions basically say to tie into each switch and their respective lighting circuits along with a ground and a hot. I found a set of instructions online for the Harley version of the module, it evidently plugs into the 10 pin connector and jumps out the flasher.

I think I will give your idea a shot, once I find that connector I think I can get this thing going. Thanks for the advice, I'll post the results.

You were correct, I installed the unit and it works like a charm on everything but the front turn signals. Not sure what is going on with them yet, seems like a grounding issue because the running lights are also dim. Seems to be unrelated to the module given that. Maybe I knocked something loose when I had the tank off.

Regardless thanks for suggestion, I'm very happy with the results.

Before you go back behind the tank, Pull the turn signal lenses off the front lights. The sockets are chassis grounded, and may not be making a good ground. On my bike, I had a similar problem going on. Once I got in there, I found the sockets were slightly loose and kind of crusty. I just used a piece of wire and tied it to a good ground, and touched the other end to the side of the socket. Dim light went bright, and I ended up replacing the light assembly. Cheap from JP cycles. That was a easy fix.

I have also run into a different problem as well. The wires that exit the trurn lights on the front make a sharp turn as they exit the housing. If they are old originals, the wire covering and the wire insulation can split and short out. I had this problem when the original turn lights were on the bike also. I have since replaced the lights with aftermarket bullet turn signal lights that have a ground wire. No more worry of self grounding sockets.

Check those sockets, good chance they are loose, and crusty lookin. The lense gaskets were missing on mine, and I assume water and dampness was getting in there.

Thanks, I'll look at them again. I pulled them off and cleaned the inside of the sockets, but honestly didn't consider the socket having to ground to the housing. Weird that this started after the work I did and on both signals, but the fact that lights and turn are on two different circuits leads me to believe ground.

No self cancelers on your bike.

OK, so I replaced turn signals, pulled apart the spotlights and mounts and cleaned all corrosion, but to no avail. The parking lights work great now but still no front turn signals. The rear ones work fine and each of them are supplied through their own circuit after the switch, so I'm at a total loss unless both wires feeding forward have failed for some reason right after I installed the module. Has anyone else ever run into this or something similar, grounding made the most sense but the parking lights work fine as do the headlight and spotlights.

There should be only 2 wires exiting the front turn signal light (2 on each side) 1 is running circuit the other is the turn signal. NO GROUND WIRE they're self grounding. Check the wires for power. One should be constant (with ignition on) the other should get intermittent power when that sides blinkers activated. If not follow it back to the plug under the tank, then to the turn signal module.

Thanks Ranger, I was hoping not to pull the tank again, but I am beginning to believe that connector is the culprit.
