LED Turn Signals

I am putting my Quota back together. I Installed a LED Flasher Relay. I installed LED turn signals front and rear. I had the LED front turn signals hooked to rear the regular turn signals. They worked great. I was working from front to back. When I installed the rear LED turn signal all four turn signals flash like emergency flasher regardless using left or right switch. If i disconnect one rear turn signal then 3 flash. Anyone in the LED know? This shouldn't be this hard.
I appreciate any help.

I assume you are using a blinker module that is suitable for LED's. Since LED's draw so little power, they need a special module.

What is probably happening is the left and right are connected via the dash signal indicator bulb. It is ridiculous but pop the bulb out and see if the blinkers work fine. This is what I did and I developed additional habits regarding cancelling the signal.

I looked for the proper parts to fix this and found a good description instead:

Thanks,
I just saw this on advrider after i saw your reply.
http://www.advrider.com/forums/showthread.php?t=717330

So I need to add 4 resistors to the + wires? I have no paper work on the voltage. Is there a rule of thumb for the resistors?
I have never put a resistor in any type of circuit(Does marriage count?). I looked at the Kaw 250 link. It's extremely well written but i'm just perplexed.

I removed the bulb and the turn signals work properly




Thanks,
Les

I would ignore the resistor info. If the signals work fine after removing the indicator bulb then resistors are not the fix.

Fix 1: remove indicator bulb and live with no indicator (what I did).

or

Fix 2: wire two very small LED's into the circuits at the indicator so R and L circuits ground independently through one or the other LED lamp and they individually light to function as your new dash indicator. LEDs are "light emitting diodes" with "diodes" being important. A diode is like a one-way check valve for electrical current. In the case of LEDs, when the current is flowing the LED is lighted, when the current is stopped like with a check valve, there is no light. In this fix the indicator bulb is replaced by the two LED's and R and L blinker circuits are split or effectively split.

or

Fix 3: wire two small standard diodes in so the L and R circuits cannot bleed power into each other via the indicator bulb connection they both share. Remember the check valve function of diodes. This is what is lacking in the standard circuit. Regular bulbs use so much power this doesn't matter so much since it is hard to light the opposite circuit via the indicator bulb pathway.

At this link: http://faq.ninja250.org/wiki/My_LED_...27t_work_right

This diagram is the fix and it relates only to the indicator: http://faq.ninja250.org/images/7/72/830372.jpg

You can see the two diode symbols added near the center of the diagram on the right were the bulb no longer is shown. This is for the Fix # 2 version with two small LED's at the diode position. Fix #3 would be standard diodes and keep the indicator bulb where it was on the diagram on the left.

Some more links:

Look for "Genesis Metric Cruiser Diode Kit."

Use this scematic:



this will work but instead of buying a kit just unsolder a 2 diodes from some old electronic equipment
you might have (old VCR or TV or Radio you prob have laying around

if you ever return to normal blikers it will still work

The diode kit is only a few bucks and will fix it.

I did hear that there are some solid state LED relays that have them built in but I haven't tried one myself.

I appreciate the insight. I am mulling it over the path that I choose. I like having a turn indicator. Here's the plan I'm going riding on Strom tomorrow and I will blow it off for a few days. The bike is apart(Plastic parts)for resistors. It's now or in the future. I'm kinda of tired of installing then removing parts over and over.



Thank you for all for the help. Everyone on advrider and Quota groups have been kind and really generous with advice and help.
