hi everyone

I bought one of those all-in-one LED strip with running, brake and turn signals
There are 5 wires:
1) ground
2) running light
3) brake light
4) left signal
5) right signal

they all share the same ground wire (1)

BUT, my bike's stock wiring has separate ground wires, 1 for running/brake, 1 for left signal and 1 for right signal respectively

if I connect the LED strip's ground to the running/brake's ground, the turn signals will always be blinking as if its circuit is always closed

how should I wire to make the LED strip's turn signal function normally?... thank you......

 

It is likely the pinout is incorrectly labeled. All grounds on the bike should be the same, you could wire the LED strip ground directly to the frame instead of the plug if you are uncertain of correct pinout, the frame is wired to the negative terminal on the battery (ground)

You should be able to measure continuity between all the ground wires, if not something is wrong.

thanks for replying mate

I tried to wire the LED strip's ground to bike frame

the turn signals are on as well...........

LED strip's fault?...........

 

It might be. The running light gets power from the ignition switch, the brake light gets power through the brake switch, and the turn signals should get power from the signal relay which is what is controlling the flash. The ground is just a ground. It may be that the relay is now integrated into the actual LED using FETs. If you have a wire, connect the ground from the strip to the bike ground, then without the strip plugged in, use the wire (clip lead) to come off of the bike battery's positive and send power to the left or right signal pin. It should either stay lit or blink. If it blinks, there is something more to the LED strip than just LEDs.

I work a lot on bikes, but never anything newer than 1990s, so it could be a newer design I am unfamiliar with.

and if I wire the LED strip's ground to the ground of bike's turn signal

even the running/brake light will only be on when I put use turn signal....

does that mean the grounds are really separated before reaching negative terminal of the battery?

 

Not necessarily, it could mean that you are grounding out the turn signals, because of incorrectly labeled wiring.

just tested, it lits but doesn't blink, stays static

 

Then next I would measure voltages coming from the signal pins on the bike connector. Find the one that has voltage when you turn on the left signal, and do the same for the right, then make sure the pins match.

=(

I searched on youtube

many bikes share the same ground between

ah.. I don't have voltmeter with me =(


my bike's wires are:

left signal
-positive
-negative

right signal
-positive
-negative

running/brake light
-running light
-brake light
-negative


whereas the LED strip has 5 wires only as above...

this is my bike's service manual... page 488 is the wiring diagram

thank you so much for helping out mate....

I noticed these together with the connectors

the square ones are relays right?...
then there's that piece... I also noticed it has ground wires connected to them... (from turn signals)
