Harness Installed TSCU MOD for LED Conversions

[Weapon]

ok I have reread this thread a few times now, I understand you are no longer making those widgets to make the tscu work correctly POS, but I have a niggling feeling that I am missing something.

I have installed a sh775, which takes care of the load(I know its only relevant to this in regards to what leds do to a stator). moving on, I have 4 led turn signals installed and am purchasing the recommended relay (the novita ep34) to install in the factory plug) as my understanding goes this should just work. but I have a feeling I read somewhere that a wire from the tscu needs to be grounded but I can no longer find that reference.
if any one can give me a sanity check on this that would be appreciated.

This is the compete mod. All need a ep34 but you also need another relay; a mini as suggested is much smaller and will work as long as it has a Normally Closed connection.

I get that but was hoping to get it working just without the autocancel for now. Is there something i have to ground?

pin C of the EP34

Ah thankyou so much! Once i can order one of those little relays i will try your mod.

Didnt work. It has a pin b l and e. Grounding pin e didnt work nor did grounding pin l which is in the center

If you look at the schematic, I used the OEM color codes for which pin is which. The labeling of pins on aftermarket flashers is pretty confusing as everybody uses a different nomenclature.

C,L,B is the nomenclature on your old OEM flasher (you have one of those right?)
Make sure that your harness wires go into the correct locations of the OEM 3 prong plug on your harness. I have provided the wire colors.
If it is OK plug the EP34 in and ground C which is Black/Blue. (as the schematic shows)

I have made this work and Steve also so if it is not working you have something wrong.

check that you have +12V on O/G
L is normally Load or Lights

Ok yup colors are right. My relay just buzzes with no flash when i do that. The flasher is an sg141e. Which i was told is the same but its probably not the same so on my way back to part source :S

What happens when you pull the Bl/B to +12V? What happens when you leave it open?

[Weapon]

Open it does nothing. Didnt try feeding it hot as didnt want to fry it

As mentioned in the first post most of the differences in FLASHERS seem to be where the pins land on the flashers not necessarily polarities. All of them are a high side control relay (Normally closed) that allows power to feed through but disabled when appropriately controlled. In the case of OEM that was when you applied +12V . For most modern ones it seems to be when you ground.

If there was one that disabled with a high signal on BL it would work with the OEM TSCU.

Ok i just got home with a ep34 and it worked a charm. I should have listened to the little voice that said dont let this kid sell you this other one just because he cant find what i need. Once again POS thanks so much for your patience and help!!

Thanks, glad it is sorted. You are very close now to just getting the TSCU to work and relay will work that has a NC output (87a)

[Weapon]

Yup going to tackle that for sure using one of those little relays you showed on the main post

Great Thread.

I have a gs1100e that I just bought new LED turn signals for. I have the polaris SH775 on my bike already and my auto cancel does not work and I can live without it.

So if I understand correctly ???

Option A is to purchase a EP34 2-6 lamp flasher relay and it is plug and play after grounding one wire to the frame.
or
Option B is to buy load resistors and wire one in line with each turn signal.

I imagine option A is more affordable and looks simpler -- any pros and cons would be appreciated.
