LED Indicators + relay

[Guest]

Wow, so this is really anoyying. After buying some LED indicators for my bike, i put the back two on, and all was fine.

I then got the second pair to put on the front, put them on, and they were all out of time and way to fast.

Ofcourse! the relay!

so off to bikers world i go spending twenty quid on a Motrax universal flasher relay. got back and tried to fit it, and nothing worked. all the indicators stayed on constantly and my dashboard turn signal light wouldnt come on. boo.

so after testing the relay i just got, with a ohmetre, i returned it due to being faulty.

Then after a short journey to halfords i got a yamaha LED flasher relay, shouldnt really matter about the bike model right? cut off the connector and put it on.

And now ive blown the front two led indicators

on my bike, the back two indicators are single wires each, but the front two join together to make one cable which then goes.. somewhere lol.

So ive ordered some more indicators , in hope they will work with the new relay.

Any ideas?

You could try this relay which is bike specific

Haha, this is the Motrax universal one i tried i think.

i just want led indicators

They do seem to be bike specific though, are you sure they gave you the correct one?

the front two share an earth wire, the back two are earthed through the frame. hence only one power wire..

the universal one was just broken. so we're trying a yamaha one now.

wtf? okay right, so if we have three LED indicators on , and one bulb, the side with the two led indicators on works fine when indicating that side, the dash light works and so do the led indicators. however, when we puch to indicate to the side with the one bulb indicator on, the dash light is very dimm, and all four indicators start flashing . this also happens when all four led indicators are on too. HELP??

[Guest]

triple post =]

we've found the problem, we disconnected the dash lights, and all four led indicators work fine and correct. so what now?

[Guest]

when i made a led tail light unit for my bandit ,

i used these http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=350220703670 ( i bought them from this ebay member )

all the wiring is done on the indicator wires themselves and not at the indicator relay, i used bullet connectors so i could change back to standard easily if i wanted to, they do get a little bit hot , so i mounted them out of the way under the seat using a piece of aluminium plate as a heat sink.

hmm, i dont really want to fanny about with resistors. i just think its really wierd how everything works fine when the dash light is out of the question.

could i not just make a seperate run off from the relay straight to the dash light?

EDIT

just tried that, the dash light came on and off very dim, and the led indicators (only the correct two) went fully lit, then dim, instead of on and off.

im pulling my hair out.

EDIT

we thought, why not connect the two dash wires to an ear and then to the indicator switch wires too. so, when the switch is one way, it completes the circuit making the dash light come on and blink correctly. and it worked. untill we tried to connect it to left inidator switch AND right. because when theres a live feed from one, it goes to the dash light, and splits to the other switch side too (its hard to explain) making all four indicators come on. can you get anything that only lets a current travel one way? a diode? one that wouldnt get too hot or blow over time?

EDIT

im getting really confused. surely the relay should act as a on/off switch? but the power to it is constant...

[Guest]

I spoke to my friend whos been riding several years and he said the reason the dash light is messing it up is because its not led. We're getting some diodes tomorrow for that though.

so after riding it today,without the dash light... the indicators run fine, unless the engine is running and revving where they then flash too fast. anyone have any ideas? i want to cry lol.

EDIT

im gunna try anything now. what resistors do i need? can i get them from maplins or is it a ebay job?

Also, if i get this sorted, and they work, ill make a donation to tmbf. because you guys are lovely to me.

EDIT

would one resister at the relay do? or one on each indicator?

I've done it! So heres a guide for everyone.

What youll need:

+4Led Indicators

+Some male and Female Connectors

+Some diodes - http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWNX:IT

+A LED Relay

+A Resistor / disipator - http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWNX:IT

+wiring tools/cable ties / insulation tape etc.

RIGHT

Step 1

Remove all your indicators from the bike, these should be Bullet Connectors, you can remove the female connectors from the indicator wires if you need too.

Step 2

Remove the seat and tank, making the wiring visible. Connect the new LED Indicators to the existing wire.

Step 3

Replace The Relay, any relay will do, im using a yamaha one. Just cut the connector block and use male/female conectors.

Step 4

It starts to get complicated here. If your lucky, your indicators will be working , including the mimic (dash light) too. If not, maybe all four are flashing, or not in time, or maybe too fast if the engine is running. Dont worry.

Find the two wires that go to the dash light. Cut them from the block they are going to, and fine out which one is the earth, (not always colour coded use a ohmetre)

Step 5

Solder your diodes in the correct way. Both wires comming FROM the connector block show be able to flow through the diodes. Once you have soldered a diode to both of the two wires, then solder the opposite ends together.

The red circle shows how the diodes should be after then connecting the end where theyre both soldered together, to the live indicator mimic wire. The one you cut that was going to the Connector block.

Step 6

The free wire, comming from the mimic is an earth to complete the cicuit. You have two options, fine a earth allready there and cut into it, or give the whole circuit it own earth. Thats what i did, just to be safe, straight to the battery.

Shown by the blue circle.

Step 7.

Everything might work now. However in my case, the indicators flashed faster when the bike was revving, due to the battery being charged.

So go back to the Relay and remove the connectors you put in.

Getting two new connectors, tie one wire from the relay (stripped) and resister together, putting them into a connector.

Do the same with the other two wires. This should give you two wires going into each connector, giving you two connectors. then connect this how the relay was originally connected (Its all a bit confusing)

We then put the resister on the ignition module, as it doesnt get very hot.

Ask me if you need anymore help ;]

Glad you got it sorted , one thing that confused me though was why you had to change your dash lights to Led, the reason LED bulbs flash quick is the require a very low voltage to operate, so it`s like having a blown bulb in, all the resistor does is increase the voltage to the relay so slowing the flash down, so dash lights should have no bearing on the problems you encountered, this is how i wired mine up

by the way are your led dash lights any good, and if so where did you get them from, i replaced my dash, speedo and tacho with led cos i was sick of them blowing due to vibes, but i found them too dim so swapped back
