Motorrad Leuchte leuchtet nicht?
So nochmal,
habe mir ein 12V Rücklicht für mein Motorrad gekauft. Das originale leuchtet, wenn man es anschließt. Das neue nicht. Die Lampe geht, wenn man sie nur so an die Batterie hält. Die Verkabelung ist auch intakt und wenn ich den Kabelbaum bis zum Licht prüfe ist auch ein Stromfluss da.
Wieso leuchtet die Lampe nicht?
LG
If you had a lamp with an incandescent lamp before and now a lamp with LED, it could be that the onboard electronics now have a resistance problem, as the resistance behavior between LED and incandescent fruit is different. Your physics teacher could help you with the jumps 🙂 Or the friendly specialist trade, because you have certainly been advised in a local motorcycle business, as it is, and not just ordered anything online, right?
I worked myself in a kfz workshop and also got the luck that an LED was installed before it 😄
Perfect. Then you know what was meant.
Then I guess it’s going to be a mass problem.
A cable goes to the lamp, back or down to the contact. The outer part of the lamp is connected to the holder. The holder must be connected to the chassis. Any helper directly with the screw connection or a cable must be pulled. A picture would be helpful. On the small problem you realize how important the theory is.
I can try to explain so well. Go into the new lamp 3 cables. Mass, brake and backlight. The holder of the lamp, as well as the license plate holder on which the lamp is attached, is completely made of plastic. I connected the cables to the same cable of the cable harness. I’m switching the bike to nothing. Mass errors can be, put another extra ground cable to a ground connection.
The light has a continuous increase. This lights up in the mass. It therefore requires no mass from the chassis. Different from the backlight. There, a mass must be applied which takes place either separately via the fastening screw or via a cable. Current flows after the switch is actuated. So, the 3 cables are two for brake and one for backlight. Brown is mass. Yellow/green is brake. Grey or gray black is final light. Like I said, you have to organize mass for that.
There must be a contact on the light carrier for a plug or where the screw passes through a metal loop. Jann also be that there is no mass on the fender. Passed by corrosion. Test lamp and multimeter would be helpful.
Yes I will put a separate ground cable now, thank you!
if you kept it to the battery, then it was plus and minus connected, so you have to imagine the whole motorcycle is minus!
And then?
You bought a new pear and not a light, didn’t you?
Complete new LED light
Just check if the new lamp has a mass contact.
How is that going? 😇
a lamp that has no contact with the metal of the vehicle must always have a 2-pole (plus and minus) connection. most are connected to the vehicle mass via the screw connection and therefore only need one cable (plus)
simply compare it with the old lamp or drive into a workshop.
