Unplug Turn signal module, motor dies
This just started..... With the key on not running, Turn signals ( all ) work just fine.
...
With bike running the signals, quick flash then stop working. Unplug the module and the motor dies. ?
After the motor dies, and still in the run position with module still connected the Signals work.as should. Just not working when running, other the quick flash !
What am I missing ? Is there a ground I am missing.
The orginal Module was replaced when the OEM failed.
I used a.... http://www.signaldynamics.com/self-c...signal-module/.....Worked fine till yesterday.
Hope someone understands this !
Looking at the wiring Diagram, i see the Ing switch, supplys current in acc. and run.to Module.
Talked to Signal Dynamics. They are willing to test it for me, since it has a very quick flash, then nothing
The last time you-all help me. Hope so this time also.
Thank you if you had any ideas:
Bob

Couple of thoughts. 1) What is it charging at? Overcharging will do crazy things. If it's charging ok, 2) What happens if you disconnect the 12+ into the module and module ground? Does the bike run normally (except for signals). That should tell you a lot.

4 ways
Charging is fine. I'll try the disconnect of the +12 and the neg, to module and see what happens. It should be just like unplugging it.
The thing why is the unplugged Module killing the motor. ....Looking at the Wiring Diagrams. there are redundant grounds and no visible possible problems with what I have.
Factory harness all but the aftermarket Module.
Plug it back in with just killed motor, in run position,non running... the damn signals work all but the 4 way flashers.
The 4 ways do not work, motor running or not running. Starting to believe the module is my problem.
Going to ask Dynamics if the bike is on a charger on high voltage, will it damage the module if the key was in the run position ?
Signal Dynamics is, willing to test it, and if there is a problem replace it.
Thank you for your reply.
I'll let you know how it goes

Lack of good ground ?
Ed Ramberger
Disconnecting only the ground wire from module kills the motor. Disconnecting the Pos +12 only does not kill the motor ?
It seem there is a lack of a good ground.
The NEG battery is grounded to the the motor mount bolt factory install.
The diagram shows three wires at main ground. One goes straight to timing module, 6 pin plug.. one to Tach, Speedo and indicator lights 12 pin plug third ground wire goes to turn module /headlights basically everything else.
Where is the location of this three wire ground location ?
Any body have the locations of all grounds.
This link is a diagram of 2002.......https://serviceinfo.harley-davidson....ocument%2F5528

I don't believe I posted a link - I typed a description. On a Touring model the ground studs are in the recessed cavity under the seat by the backbone. Carbureted bikes use a single ground, EFI have 2 grounds - clean and dirty. The reference to a link is that I was saying that in the picture iin your link, the stud is shown above the box containing the witring color key.
