LED Turn signal Relay question...
« on: January 05, 2016, 04:44:40 pm »
Hi all,

I have searched high and low, so if I missed this, please point it out to me...

First TLDR, here's what I know so far:
1. To fix/prevent hyper flash when installing LED turn signals you have to modify the turn signals power draw (Load equalizers/resistors) or modify/replace the relay. 

I'm trying to modify or replace the current relay.  I don't really care about the auto cancel turn signals. If I can keep them, great; if not, I don't care. 

*********************************
Methods I'm looking at:
1. replace the relay such as this:
http://www.yamahastarstryker.com/20-how-tos/2275-how-install-electronic-constant-rate-turn-signal-relay.html

2. Modify the relay such as this:
http://www.650ccnd.com/PDFs/Flasher_mod_Revised.pdf

3.  Someone mentioned that the 2015 Stryker has all LED signals already, so I'm curious about just popping in a 2015 Stryker relay.


********************************
Here's my thoughts:
METHOD 1: I've tried method one.  It didn't work.  I'm guessing our wiring is different from what that Stryker model year had.  Perhaps it's like the 2015 (See method 3). 

I looked at the wiring diagram and it looks like we have these wires/functions (Someone check my math, I'm no good with electrics):
Br/G = Pos
Black = Ground (Neg)
Br/W = Load
W/Y (2 in one clip) = Signal from ECU/Speed sensor?
Y/R = Self Cancel?

Does that all look right?  I'm going to build some test wires this week and try this out (getting the wire's out of the holder intact is a bit of a pain). 

METHOD 2: Scary.  I hate soldering.  I have done it on auto ECUs, so I can, I just don't like it.  BUT... it should keep auto cancel and OEM look under the "hood".  However, would this essentially equate to adding load resistors to each line and cause the heat/power draw issues associated with that method?

METHOD 3: Anyone got a spare 2015 Stryker laying around? 

Thoughts?

Hi mate, I've replaced all my indicators to led, by far the easiest solution is just change the relay, took me 15 minutes to find swap and put back together.  I'm in the uk and got it from  Bikermart.co.uk, it says it fits Honda Yamaha Suzuki so I'm guessing it's a standard fit.  If you're just changing a pair, the inline resistors work a treat if you're handy with a soldering iron.

Pir8:
Many of us have swapped out to LED turn signals, and you either have to swap out the turn signal relay ... OR put a big resistor on each LED bulb - which is kind of stupid, since one of the big advantages of the LED is that they use less power - which the resistors would increase back to original...... SO .... on to your solution.....

if you go to this thread (https://www.yamahastarbolt.com/frequently-asked-questions-6/has-anyone-install-led-cluster-bulbs-like-these/15/) Texas explains how he modified a $15 LED flasher from CustomLED or CycleGear to work on the Bolt. It basically involves removing the pins from the connector on the flasher and connecting them to the proper connections in the original flasher relay connector on the bike - and completely removing the original flasher relay.  All you really need is a little electrical tape to hold everything in place and insulate things.  Took me a whole 10 minutes - and that was because I wanted a pretty job. It's also completely reversible. Unfortunately, as you said, you do lose your auto shut-off, but I can live with it.

And the LED signals from Custom Dynamics are GREAT - expensive, but REALLY phenomenal lights. I now have 3 brake lights in the back, rear running lights, AND front running lights.  They are meant for the Stryker, but fit the Bolt nicely.  The rears need some wiring and creativity to hide the extra 2 wires, but it IS possible to make the whole thing invisible.

That looks a lot like it. I expect that there are several manufacturers who build similar relays. The one I used was an ELFR-1 that I found on eBay.

The biggest difference in most of them is the connector - which (if you use Texas' method like I did), you're taking off and trashing, anyway.

Here's one on eBay for $7.50, plus free shipping (from Hong Kong - so it's close for all you Aussies...)

Or you can just search for ELFR-1

AHHHH!  Thanks all!! Holy cow.  I looked all over the place.  I gues "LED" and "Relay" were just too common. 

Really appreciate it.  I have Muth Mirrors up front now, and Kuryakyn RTB torpedos on the back.  I like the look.  I'll post some pics when I get a chance.

That's the one Rowan.  Seat comes off, side panel with the key off and it's clipped to the side, I can't remember whether it's just behind the battery or at the nearside nearly under one of the modules.  I'm sure someone will have a better memory than me!

Yeah, Major  - it's buried down low in front of the battery on the left side...   Easiest to unplug the ECU to get to it, too.

OK All - If you're looking to modify your flasher relay as per Pir8's Method 2 from the first post - I found another place that has a copy of the needed PDF file that shows you how to do it: https://www.dropbox.com/s/f3jvewniwcz1qab/Flasher_mod_Revised.pdf?dl=0

I WILL also copy and post it in the Tech Library, soon as well.

AHA!
MJ: I'd seen your post, but then forgot WHO it was!  I did post your PDF in the Tech library for reference, though, and I'll give you credit as soon as I get back in there to work on it. 
I DID find a SLIGHTLY easier way to get into the relay, though......  I used a small (9mm) box cutter knife (the little OLFA one) and slid it down on each side of the two offending brass contacts - and actually cut the plastic tabs that lock them in. Then you just pop open the tabs on the sides and a little wiggle gets the plastic cover out of the way.

I think I'm going to try the other method that I'd found in another place (It's also in the same post) - and just try filing the resistance loop, rather than cutting it and trying to solder a resistor to it.  Like everybody else, the circuit board is siliconed in there, and it would be a small nightmare to remove, so slipping a small (jewellers' type) file in there seems to be a lot easier than trying to get my cutters, then a soldering iron and resistor all in there to do the solder job.  It's more hit and miss, but if I file through, at least I can still fall back on the resistor method!

I posted the whole thing in the Tech Library..... so far.... LOL

A question regarding replacing the relay...

I'm switching the tail lights first to LED, and leaving the front alone until i find what I want.  With that said, if i replace the rear turn signals and swap the relay, does that affect the front turn signal performance if they are OEM?

Nope.  They will flash like normal.
