another led thread need help

Ok I have all four led turn signals I got a electronic flasher relay now all four just flash what am I doing wrong.

 

A ) You may have crossed wires at the flasher relay - Check manual, other posts or wait for other replies
B ) Some people need to buy multiple flashers till the get one to work. Did you buy one designed for LEDs?
C ) You may have crossed the wires on the light installation. Sometimes aftermarket wire colors are funky. IE black may be hot NOT ground like our Yamahas use. Check all for light's wire connections/colors.
D ) Did you do anything else like change handlebars? Paint handlebars (and lost the ground because of it)? Non-oem signal switch? Any other changes? Did the lights blink BEFORE you went LED with new flasher?

 

Do you mean all four flash at the same time? Are they flashing with the flasher control switch centered? If so, your signals are wired incorrectly.

The flasher turns power to the control switch on and off, there is no way it can cause the situations above.

 

It all worked with the stock lamps and stock flasher. with the electronic flasher all four flash when selecting right or left.

 

So I found it will work with the stock lamps hooked on the front with the rear leds hooked up. so what does that mean I need those load resistors for this to you. or what could I use

 

Your wiring is probably correct.

Here might be the problem (from my own experience, with Chacal's insight): The turn signal indicator lamp in the instrument cluster allows a small amount of current to pass through its filament to the opposite turn signal circuit. This does not matter with conventional incandescent bulbs which require a lot of current to illuminate them.

LEDs, on the other hand, require very little power, and enough of it is leaking through the indicator bulb to light them.

Here's how to test whether this is in fact the issue: Remove the turn signal bulb from the instrument cluster. If the signals flash correctly, that's the problem. Adding resistors to the circuit is a poor solution, since it they work by wasting current to simulate inefficient incandescent bulbs.

Simpler, cheaper solution: Replace your instrument panel bulb with an LED. While you are at it, consider replacing all cluster indicator bulbs with LEDs. They're cheap, conserve electrical power for better purposes and will probably never expire.

Chacal has LEDs for instrument cluster, as well as LED replacements for the turn signals themselves and the electronic flasher to to control them.

 

WOW some thing so simple. the thing is I put leds in the gauges but I never touched the control panel part. thank you a lot they blink like they should now. now I can finally move on to something else.

 

Well it works fine with a led in the turn signal gauge. but once the bike is on it doesn't work. they all flash again. but it does work just fine with no light bulb in the turn signal gauge.

 

The LED in the indicator cluster is supposed to stop current from crossing over to the other side of the circuit. From what you describe, it seems to be that the LED is blocking the relatively lower current from the battery but not the higher current when the alternator is running.

Since everything works without a bulb in the indicator socket, that narrows the issue down to the performance of the indicator LED. All LEDs are not created equal. Make sure you have the right automotive spec.

For a better understanding of what's going on, perhaps you could check the voltage across the indicator bulb socket, first on batter power only, then with the engine running at 2500 rpm.

 

Did you wire all four lights through the same resistor?

If so...

I thought they were suppose to have their own individual resistor... 4 total.

 

The resistor issue can be confusing. In my experience, auto parts stores automatically prescribe them for LED use, because they assume use of the old stock flasher relay.

Resistors are used to fake out the old thermal-type flasher relay which relies on a lot of current and heat to work the switch. Resistors are not required with electronic relays made for LED use.

The fact that the LEDs flash correctly (without the indicator lamp in place) shows that the flasher relay is working correctly and that resistors are not required.

 

If you could some how reverse the polarity of the indicator lamp, it wouldn't matter hoe much power it bled into the other side of the system, LEDs are diodes and will only accept current in one direction...not sure if it would work, never tried it but I took a shot.
