LED problems !!!!!!

[pranaferox]

hello everyone

i`m trying to fit some led indicators to my rsvr 2000

i have wired them up but the dont flash ,they come on but dont flash

i have tried the leds with resistors and the old relay -the left and right come on separately as per normal but the dont flash

i have tried the new relay (led type) and the old relay with no resistors and both sides come on and stay on !!!

any ideas ?????

thanks in advance

right voltage???

i had this problem with my mx50 when a fuse had blown...

[pranaferox]

yep

12 volt battery....... 12v 1 watt leds ,12v 1-30 watt relay

???????

[finpos]

I suppose the obvious thing to ask is : Are you sure you replaced the correct relay?

[Mr.Everready]

Have you wired the resistors correctly ?

On my ZX6 I put in a new relay but it only worked on the rear lights so had to use resistors on the front aswell.

yep, its the correct relay,

the resistors are all pre-wired ,using one on each indicator,


?????

[finpos]

Looks like you'll just have to go right back to the start.

I'm assuming you don't have a multimeter so use one of your old indicators as a test bulb. Connect one wire of your old indicators to an earth point on your bike, use the other, loose, wire as a probe.

Ignition on, switch indicators on -> indicators light up, don't flash
Pull out relay -> indicators go out
probe onto each of the (two?) connectors in the relay socket. One of these should make the light come on. call it "12V"
use a short length of wire to connect "12V" to the +ve (red? or marked "+") wire or terminal of the new relay.
connect probe to the -ve (black or "-") terminal on the relay -> light should flash.

If you get that far, the relay part is ok and we'll worry about the bulbs next.

[pranaferox]

thanks for that finpos

it would appear the new relay works (the old one won`t funny boing sound when it wants to flash)

so i`m guessing on to the bulbs??


mr everready .......sorry if that came across as rude didnt mean it to !!!!!

they have connections already on them so can only fit one way

cheers

[finpos]

Ok, so far, so good.

I think Mr. Everready has touched on the possible solution, You need to match the Wattage of the bulbs in the circuit to the relay (1W to 30W).

Your LED indicators are rated at 1W but I'm kinda suspecting that is just a nominal value, and they use a lot less. So two added together is less than 1W, which is too low.

With Resistors on each of the indicators, you are probably at something like 44W. Too much.

So, in short, with no futher beating around the bush, try using only one pair of the resistors you were supplied with, e.g. fit one to the front indicator but not the back on each side. That should give you about 22W - just right.

[pranaferox]

ok,

possibly getting somewhere,

one resistor on each side on the front,

indicate left the left side comes on no flashing,

indicate right right side comes on no flashing,


cheers

[finpos]

Hmm, that's interesting.

Now, I haven't got a clue what's going on.

finpos.

[finpos]

Ok, I had a thunk about it.

The only thing I can suggest is that there is something strange about the circuit for the indicator repeater light on the dash. You very occasionally see this on small bikes.

Next steps I'd suggest:

* On one side, disconnect both the front and back indicators.
* plumb just one of your old indicators into the front or back
* it should flash in exactly the same way as it did before when you tested the relay. If it doesn't, there's something odd happening. Take the repeater bulb out, see what that does.

If it does flash, plug one of your LED indicators in as well (without resistor) and see what happens. It should flash as well.

[pranaferox]

thanks finpos

i`m calling it a day for now ........before i balls up something else

will get on it soon and report back

cheers

Most flasher units use Bi-metalic strips.

Ordinary bulbs are usually 21Watt and draw enough current to heat up the strip, thus making and breaking the contact (flashing).

Your LED`s aren`t drawing enough current for your flasher unit, in my opinion.

Hope this helps.

Lo Again,

I found a wiring diagram for an rs125, which I'm assuming is much the same as your bike.

It does indeed have the weird crap I refered to going on with the repeater warning light. So, my prediction is that if you remove the repeater bulb, your indicators will start working (with zero or two resistors, not sure about four).

While you are trying to pull the bulb out have a look if the two wires going to it are red and light blue (Azure if you want to be Italian about it ).

Now, if you want your repeater to work as well as your indicators, you are going to need two 12V Diodes and a length of wire. Plus butchery to the max.

hello finpos

i have tried to taking the repeater bulb out and they dont flash !!!!!!

not tried the old indicator trick yet

below is a link to a wiring diagram (in pdf) for the rsvr (its on the 3 section)

cheers PF

Well, I'm flummoxed now.

The diagram is almost the same as the one I looked at earlier, so it does have this potential problem with the repeater bulb. So leave it out for now.

Just to confirm:

You are using your new, led-type relay
The repeater bulb has been removed
Both of the LED indicators are connected up, with their +ve wires (probably red?) going to the RED and AZURE wires on the bike's loom
No Resistors fitted anywhere

That should work. If not, try the single, old indicator as discussed earlier and see what happens.

Now, I'm off to the pub. If I post anything else tonight, it'll be ill-considered bollocks.

LED indicators need a relay specifically designed for LED's. they sell them on ebay. if you use the old relay for the bulb type indicators(standard) then the indicators dont flash, just stay on.

my friend had the same problem untill he got a relay especially for the LED's.

But before I go to the pub:

I just noticed in the manual that the standard indicator bulbs are 10W bulbs, not the more usual 22W bulbs. It's very possible that the resistors you were supplied with are designed to replicate 22W bulbs. That, I reckon, is why your original attempt (4 resistors plus original relay) did not work.

So, the other thing you can try is:

Replace the LED type flasher with the original Flasher
Replace the dash repeater light
Use all 4 LED indicators, but with the resistors only fitted to the front. I think that should give you just about the right current draw to work the original relay correctly. If it does not work, try disconnecting the indicator that has NOT got the resistor fitted.

NOW ignore anything I say subsequently.

[pranaferox]

right then the situation is as follows

front right indicator (the leds have yellow and black wires).

yellow to red loom wire
black to blue loom wire
1 resistor

rear right.

yellow to red loom wire
black to blue loom wire
no resistor

left front

yellow to light blue
black to dark blue
1 resistor

left rear
yellow to light blue
black to dark blue
no resistor

the relay plugged in is the 1-30w led relay

(the original relay when tested as described before makes a boing sound rather than a click (is it shagged?)

the relay +ve wire is black/blue ,-ve is green

try without the repeater bulb again there is no flashing

the old indicator didnt flash

will try and get a standard style relay tomorrow


enjoy the pub ............if i was there i`d get a few in for you

cheers

There is something causing a problem with the relay, normal problem with fitting LED's is they flash too fast due to not enough resistance. If the resistance is too high this would have the opposite effect and they would come on without flashing as in your problem.

tried with a brand new standard relay ,4 leds resistors on front two,......................no flashing

disconected one indivator without resistor still no flashing



weird

[finpos]

Running out of ideas here.

The only thing I can suggest you do now is to run a couple of extra wires to bypass the bikes loom.

i.e.
On the led relay, disconnect the green wire form the bikes loom.
front relay, disconnect the yellow wire form the loom (and any resistors, if fitted.)
back relay, do the same.
Run a wire to join the green and two yellow wires together, switch on ignition, there is then absolutely no reason that the indicators should not flash.

The other thing to try is to run an additional wire from any DARK blue wire straight to the -ve terminal of the battery. NOT light blue, you'll pop a fuse.
