Kymco Visar 125 stop light not working

[DrewDc]

Hi, I've a problem with the LEDs of my Visar 125:
When I press fr stop brake or rr stop brake no rear stop LED works. The only thing that works is the position red light but it not get brighter when I brake.
I've watched all cables and fuses and it seems perfect.
What can I do? What do you suggest me to check?

Thanks!

Does the engine start?

Does the engine start?

Yes, all works perfectly except the bright led when I press front or rear brake :S

Have you checked the LED "bulb" or it's socket?

Yes, the LEDs of stop are working but they not get brighter when I use front or rear brake. Dunno what could it be

How can they be working if they don't get brighter?

Tail light works, stop light doesn’t

That's what I was thinking but looking for confirmation.....

Sorry man, I mean dimmer light (position) of stop works, the stop light (that gets brighter when I press brake) nope..

Okay, that is understood that:
1. Engine starts and runs normally, therefore brake light switches are either working or bypassed/stuck closed.
2. Tail light (dim) works, brake light (bright) does not, therefore the possibilities are:
     a. Fuse blown (other functions will not work that are on that fuse..check fuse list)
     b. LED "bulb" defective
     c. Light socket defective
     d. wires to light socket defective (power or ground)

if it is the bulb...I wonder if it is replaceable bulb or if it's like a lot of the newer LED assemblies that you replace the entire unit, rather than a bulb? Like the LED 'global market' turn signal lights on my scoot...if anything burns out the bulbs are not replaceable, you replace the entire turn signal unit.

That is NOT progress! The whole assembly for a bulb or LED? Nutz to that.

Ok man, I've just figured out this:
Downloaded wiring of Visar 125, saw that the stop light has 3 connectors (green, brown and green/yellow). 
I've unplugged the socket and, with a voltmeter, saw that it seems that in the green/yellow cable (I think is the positive +) when I try with the brown one (I think is the negative -) it always has 12v. So is it "stuck" on the stop bright light instead of brake?

I post the rear wiring, can you help me and tell me if the brown is the negative and green and green/yellow the positive? In that way I can check if in the connector it is always current that makes it "stuck" on brake light.

I cannot figure out how to disconnect the rear cable wiring of brake, but maybe I will try today, maybe it is open all time and need to be changed..

Checked all fuses, perfects.
Wiring seems good..

So, it seems, that it is "stuck" on stop LED light.

The bike works perfectly, engine, winkers, headlamp, tail light.. the only problem is the brake/position.

Here is the full wiring of Visar 125:

Sorry for mistakes, I'm italian!

it looks to me like green is your 'ground', brown is your tail light (always on, plus it powers the license plate light) and green/yellow is your brake light.

From wiring diagram (good show finding that!) Green (GRN) is ground, brown (BRN) is tail light 12 v, green/yellow (GRN/YEL) is the brake light.

Brown should show 12 volts when key is on. Green/yellow will show 12 volts when the brake is activated. Does that match what you said?

Are you living in Italy?
