LED indicator help?

[DrunkenMistake]

Hey guys after alot of pissing about I finally got my LEDs on my bike and the LED flasher relay in, tested it all and they all lit up, so I removed the Dash light for the indicator and they flashed on the correct sides, I turned the bike on with a little choke so it was at about 3grand and they flashed correctly still, so I wired everything up so it was tidy and good to go, put the tail and shit back on the bike today, fired it up with full choke, flicked the indicators to quadrupole check and they were hypo flashing, turned off the choke and held the throttle at about two, and they flashed fine,
SO.. I am so far over relays and shit, I want to know, what's an easy fix? is this a relay fault causing the problem? if so, because I can not be assed redoing it all, would adding a resistor to each of the rear indicators fix the problem?

I tried looking up the wiring diagram for "a loud one" but had no luck.

LOL yah my bad,
VFR 400 NC30, forgot I changed it

[bogan]

so the problem is if the choke is on they flash really fast? VFR400s are carb'd aren't they, so the choke isn't connected to the electricals at all right?

Uh im having a bad day with explaining myself ae haha,

at idle = 12.6 V
at 5grand = 14.2 V
Choke out = 5 grand.

Coolies... what brand/model of LED indicator relay did you fit?

Was it a two or three wire?

[bogan]

sounds like a flasher issue, if it's a proper LED flasher it'll have the timing independent of the load, got a link to the flasher you used? The voltage is right, and within range of any auto 12V gear so it should work properly.

Ebay Junk. haha and its 3pin, I know its the flasher causing the problems, but when I went around dunedin to the Auto electrical stores none of them had 3 pins only 2's and a 2 didnt work at all just lit up all four like a light, So I was hoping if I added a resistor to each of the rear indicators would it do the trick?

[imdying]

You should not need any resistors.

One of the pins is an earth?

[DrunkenMistake]

You should not need any resistors.

One of the pins is an earth?

Yeah one is Earth/negitive the other positive and the last one is switch, the 2 pin simply didnt work,

Anyway,

Update
Removed the relay, put the stock one back on (for normal bulbs) left the LEDs in and gave it a shot, nothing happend, added resistors to all four indicators and I got hyper flash.. SO I need more resistance
maybe?

[imdying]

Yeah one is Earth/negitive the other positive and the last one is switch, the 2 pin simply didnt workWeird. You could add resistors and the mounting/wiring that entails, but could be worth trying another one, like a Tridon LED04 (http://www.tridon.com.au/Products/Product.aspx?SG=8&S=35&G=478&P=104173).

Yeah I may just do that, just a matter of finding one locally if someone happens to have one floating around or one that they know works thats similar Id be keen to take it off their hands

[imdying]

Are you in Chch; could I bring you one?

Dunedin mate, although I could go for a cruise right about now..... Id be happy to pay you for it + shipping or whatever it be

[imdying]

It's attached to a bike at the moment, but would've figured out a way to get it off (grossly modified bike) if you were local.

Give Appco a ring (if no local branch, then Repco, although they're basically all button pushers now even they can't fuck it up given you have a part number)... I think that's where mine came from. Failing that, BNT. Either of those places should be pretty cheap (~$30).

I have come across eBay units that won't function correctly, but I haven't ever put any time into figuring out why exactly, I just fit the LED04s.

I see, oh thats good a bnt just opened here lol, the LED02 looks more like what Ill probably need

[DrunkenMistake]

actually, whats the difference between load sensitive and not load sensitive?

[imdying]

actually, whats the difference between load sensitive and not load sensitive?I always use non sensitive, they seem to work with any LED indicator combination I throw at them. If the price is something retarded, sing out.

[Woodman]

Repco have a narva led resistor wiring kit in the showroom with the led lights.

[DrunkenMistake]

Happy ending,

Went to BNT and they were useless, dont think I will go there again, I found their customer service crap, guy told me they dont sell Tridon and noone in NZ will and their brand was out of stock, so I went over to repco and asked the nice young lass there about 3pin LED Flashers, she wasnt sure if they had them as she had never herd of them, so she checked her big and there they were, I had a glimpse through and found the one I needed, and alas they didnt have it in stock, but they had an identical one made by.. Narva? I think it was, she had a look and found it, the only one they had and it was something mad like $55.50, she was kind enough to knock it down to $40 for me so I was pleased,
Had to buy some electrics stuff like spade clips etc, and weirdly enough they didnt sell them, went to dicksmith and they didnt have them either, shot over to Jaycar and they had plenty, so got all my goodies home,
wired in the new flasher and gave it a twirl..
WORKED! "YOU FUCKING GOOD BITCH" I think were my exact words, kicked over the motor and left it to warm up a bit so I could go through the range and see if they worked, got it up to about 10 grand and they hadnt quickened up or anything so I was happy with that, I slipped the dash board idiot light bulb back in and all four flashed, so for now im without an idiot light, but everything is wired in its nicely done, looks professional and it works!, I recorded a vid I might put it on youtube and you can see haha.

Cheers for everyones help.

Your dash light problem is because of the way the dash light works in your bike:

The dash bulb has one wire going to the positive of each side turn light.

When turn lights are on the dash bulb earths through the non flashing side (through the bulb filament)

With normal bulbs installed in the indicators (not LED) the dash bulb does not draw enough current to light up the big indicator bulbs on the non flashing side.

With LED turn signals the small current from the dash bulb is enough to light up the non flashing side.

2 easy fixes -

1. Do nothing, leave the dash bulb out.

2. Add diodes (a few cents each) .
-Cut both wires from the dash bulb.
-Put a diode on the end of the wires coming from the turn lights (the non striped end of the diode)
Connect both diodes striped ends together and then to one of the dash bulb wires.
Earth the other dash bulb wire.

Looking at the wiring diagram I'm not surprised the idiot light causes all 4 to flash (mind you I can't quiet see how it works with standard bulbs though).

Regardless, 2 LEDs back to back with the center grounded should sort out your idiot light. Either that or you could use a bi coloured led and the flashing colour would tell you which indicator was on.

Cheers for that, I was told to try using an LED bulb or add diodes, I was given a link of a VFR forum that explains how and what to do, (for the dash light) but right now im not bothered to much, I just got a WOF so I should be sweet for 6 months haha, I was told by a bike shop the idiot light was needed for a WOF, is this true?

Thought about that also, but im not too concerned at the moment

This won't work - you need the 2 diodes i mentioned above. LEDs or regular bulb for the dash light makes no difference - you still need the diodes to prevent current flowing the wrong way!

The bicolour thing is a good idea though, you'd get indication of which side is on which you don't get stock on your bike....mind you, you probably should either know which side is on because you are about to turn, or not care because it is only flashing accidentally ;-)

you do know what the "D" in LED stands for don't you :msn-wink:

I doubt they'd pick it up in a WOF, but whilst it may be refered to as an idiot light, its also there for good reason, you can't blame somebody for pulling out in front of you if your indicator is going. Unless you compulsively press the cancel button on a regular basis I think the reminder light is a good thing to have, even more so on a bike.

i think i've managed to quote this one properly unlike my last....oops.

The "D" in "LED" stands for "diode that has only a couple volts reverse blocking capability before it breaks over"

It varies with the colour, but most LEDs will only withstand 2 to 5 volts in the reverse direction. You need diodes in series with them that have a reverse block capability of higher than your bike's electrical system output.

[NinjaNanna]

Did you even look at the attachment? Where is this reverse bias going to come from?

[bogan]

Also it depends on what you want to block, I just did a 60odd LED array for brake and indicators, the quoted reverse voltage on them is 5V, but the breakdown voltage is 40, which is plenty, just before breakdown they only let 5uA through anyway, not enough to run any circuitry/lights or cause damage.

Mr Bogan, what does "∞" mean? That's what your binary string says, right? Unless your name is Az ...

Hey man, for the 'idiot light' on my bike after I installed the led indicators, I just took wires from the front indicators, added a resistor to each, put orange leds on the end and duct trapped them to either side of my instrument cluster. That way I know which way i'm turning! ;)

I have some videos on my YouTube page about the saga too ...

[Jox]

Hey, Just went thru this palava myself, got some flexable strip amber LED's an used them for th rear indicator, even bought a special electonic flasher relay, but still had the problem with the high speed "Disco Flashing" omce the revs were up. The answer was to use the original relay and put a 6Ohm - 50W load resistor between the Load side of the relay and Earth (Bike Frame), this works perfectly at any revs and means you only need 1 resistor on the bike, Oh and remember not to mount the resistor on a plastic surface as it gets pretty hot after a bit of use.

Picture attached, Now she's all Good :woohoo:

Got my LEDS and kit from these guys on the North Shore...

They were real helpful and understanding about the issues and getting it all working. Hope this helps.
