    Hey all.

    So basically I have been trying to get led indicators to work on a 2001 vtr250 by installing a relay.

    I pulled apart the guts of the stock relay cause i was going to house the aftermarket one inside it so I could use the oem mount (which is making trouble shooting a bit harder.

    bought one relay from joes (which has no markings on the packaging as to which wire goes to what =__=). every configuration for this seems to blow the 10amp fuse.

    and one from supercheap (today) which is labelled but I don't know which wire would go to what (don't really feel like blowing a bunch more fuses if I can).

    Also the front indicators have 3 leads which is kinnda confusing (with a dual filament bulb).

    I've tried running the relay with both led indicators front and back (with just the one set of the two coloured wires plugged in) and it just blows the 10amp fuse.

    So any suggestions as to what to do?

    Also I haven't been able to find a high quality pdf where I can actually view the wiring diagram.

    I think one of those 3 wires is for parking lights. Indicator and parking light in one bulb

    The service manual linked to in the wiki is a bit rough, but can be useful for finding patterns and common connections at least. It also has a short section on the turn signal relay on page 323 (section 19-15).

    Based on this, I reckon the wiring to the Supercheap relay is this:
    1. Grey, signal, goes to pin 49a.
    2. Brown/blue, positive voltage, goes to pin 49
    3. Green, ground/negative, goes to pin 31

    Have you got a multimeter? With the relay removed and no bulbs inserted:
    1. I think should be open circuit (high resistance to anywhere, no voltage)
    2. Should be +12V relative to ground when ignition switched on
    3. Should be low resistance to ground (negative battery terminal, frame, etc)

    On my bike with LED indicators, All I did was take the plug from stock indicator and wire it onto the wires for the LED. Stock flash unit did it fine. (zzr250)

    Guessing the LED indicators for the front only have two wires? This will be a big issue, as gazman said, your front indicators also have your running lights inbuilt hence three wires.

    You could just wire for indicator only but you then don't have any front running/park lights so would not be compliant. You can't wire parking power to them as well as flash, they wont flash because they would already be on.....
    Looking at your OEM lamp (which is from the right side?)
    Green is the common/earth wire
    Light Blue is the turn signal input
    Light Blue/White is park/running input
    The other side looks like it will be:
    Green is the common/earth wire
    Orange is the turn signal input
    Orange/White is park/running input

    You would need something like these.

    ok, @andtfoot

    So i'm pretty sure i've worked out which wires are which for the relay.

    as gazman said one of the inidcator wires seems to be for parking bulbs.

    So when I put in just all led indicators with no parkers they don't work, when I put one pair of led indicators in they just stay on, when I plug in a set of leds with the parking bulbs spliced into the wiring they all stay on. even with all the oem indicators in they don't flash. All the fuses appear to be fine. I'm wondering if the parkers draw less power and somehow contribute to the indicators not flashing. when I flick the switch the side that should be indicating is just slightly dimmer. I'm kinnda at a loss as to why they don't blink...

    The blinking circuits often use the other side as the earth. But I need to think about it a bit more :).

    When did you last change your blinker fluid? :p

    In all seriousness, you should be fine without the flasher unit, the indicators will flash really fast though.

    You could do the bodge thing, and just wire in some resistors to increase the load, which would bring the blink rate back to normal-ish levels.

    Please please please help. I know this is an old thread but I'm hoping someone sees this. Iv got pretty much the same problem except I haven't got as far as steampunk and am, by the sounds of it, a bunch more confused lol so I want to change my indicators to led. Do I need to remove the old relay?/were is it? I need to wire in a new one? And what do I do with the Parker/driving light wire?
