LED Help!!!

Hello everyone,

I need some help with electrical. I have been modifying my XJ650 Maxim and I decided to remove the old turn signals on the bike and replace them with LEDs. Now it seemed pretty straightforward but I guess I was wrong. The rear turn signals had two wires, so I wired the LED's identical to the old ones. The front turn signals are one wire so I wired the positive for the LED's to the old wire for the old turn signals and then took the black wire and grounded it out. Seems easy. But when I turn on the turn signals they all come on. If I turn the signal to the left or right all four come on. I know they wont blink because of the mechanical blinker module, but why are all four lights coming on?

Also can someone explain how to wire an electronic module on the XJ650? Mine is a three wire mechanical module, brown wire, brown white wire, and yellow wire. How do I wire an electronic version and any recommendations on what type of electronic version i should get. I have seen on here people are recommending a two prong version, but what happens with the third wire?


Thank you all for your help.

 

Buss 552LL (or 522LL, I can never remember) two-prong electronic flasher. The third wire is for the self-cancel feature, so you lose that feature when switching to an electric flasher. There is a way to wire resistors into the LEDs to keep the mechanical flasher, but changing to electronic is easier.

Are you saying the LEDs are a one wire signal? If they are you will have to ground the harness ground wires (inside the headlight) to the stalks to ground them correctly.

Sounds to me like you aren't grounded properly.

Inside the headlight bucket:

positive wires for the signals are one yellow, and one green. Not sure of hand which color is for which side.

negative wire, there should be two black wires that are tied into a double-female-bullet-connector. There are other black wires inside the bucket, but thiese are the only ones together.

That is, of course, provided a PO didn't hack it all up.

 

wire the back ones like the front ones, you hooked the running light wire to the turn signal wire through the led.
so power goes to a turn signal and the running light wire, that goes to the other side and powers those turn signals.
the third wire on top of those flashers goes to ground

 

Tomorrow I can link you my ebay purchased flasher that works great with 4 or more led blinkers.

 

I would like that link also for future use please

 

Thank you everyone for your reply. I will take a look at it again. Inside the headlight the turn signals only had one wire going to each turn signal. There was a green and a brown. The original turn signals then grounded themself on the post that sticks off the fork. When I took those off and put the LED's on, the LED's had a red and black wire. I took the red from one LED and plugged it into Brown, and then other LED red wire I plugged it into Green. I then took the blacks and found an empty double plug inside the headlight that was also black wire and grounded the LED's there. I even took the black wires and just grounded them to the bike and the same thing happened. On the back the original turn signals had a green and black wire for one and a brown and black wire for the other. So the LED's I took the red and plugged it into green for one and brown for the other. Then I took the blacks and connected the blacks together as the original had it. Still in the end all four turn signals stay on. I used the same wires that were there before, so that is what was so confusing. They are wired the same, so I am confused on the running light wire.

What is even more confusing is if I hook up the old turn signals and wire them back in the same way I wired the LED's they work perfectly fine. How is it that the old one's work fine but the LED's all stay on wired exactly the same?

 

Metal_Bob I would love that link to your ebay profile. I would really enjoy putting on an electrical flasher instead. Thanks.

 

I'm not selling the flasher - I bought one.

That link is now dead, but I found a pic I took of the flasher.

Ebay search "90650 flasher" and a few pop up. The 3rd wire is for grounding. That should be simple enough to do for most people



You may or may not have luck at local auto store (I didn't). Also the $2 square relays from asia didn't work for me. (I even had a replacement one shipped assuming the 1st one was fried).

The 90650 flashers may not be the cheapest, but I had no problem with them with 100% LED blinkers.

NOTE: I don't recall if I tested them with mixed blinkers, but it SHOULD work...

NOTE2: The other model numbers people suggest probably also work, but I couldn't find any locally so I got mine from ebay.

 

It's not really confusing - thermal flashers don't know what to do with LOW amp LED signals.

Try hooking up the originals (or at least one side) then also connect one led to the same side (just touch the wires to the connectors or something). This will help make sure the LED blinkers are WORKING. If all 4 are working, get an electronic/LED flasher unit.

You will lose the auto cancel feature (I don't mind). Some have had luck wiring in a relay assembly to keep auto cancel (and/or other fancy soldering) but I didn't have any luck. Surrounded by farmland and country roads, I don't miss the auto cancel feature.

 

I edited my post above to read the correct color.

You were right in connecting the ground to the double black wire connector.

This is the correct ground for the signal lights, not chocolate as I stated earlier.

Sorry if I caused any confusion.

 

Thank you so much. I just ordered one. I hope that fixes my problems.

 

It is all good. There are so many wires in that assembly I dont know how anyone could remember them all. Thank you for your help though. I am hoping an electronic flasher will fix my problem because I cant figure it out.
