POS mode on switch
-
Hey! I just bought a new left handlebar switch for my DT125R, it works good but the POS mode doesn't seem to do anything. I do not know how it is supposed to be as previous to buying the switch, the bike didn't have one. (I have the older switch, from 88-96) Any help is appreciated. Thank you!

POS means position and is on the left handlebar switch, on most bikes that turns on the small bulb in the headlight but on mine it does nothing and I don't know if it's supposed to do something
@Kristóf Here's the 1989 to around 1998 3NC wiring diagram. As you can see with the lights turned to POS or On, at the headlamp switch yellow/red (main feed to the lights) connects to the blue wire for the front POS and rear light (yellow/red briefly becomes brown at the 3-pin connector just upstream of the light switch). This then connects to blue/red at the ingition switch and goes to the front POS and rear light so take a look at these wires and see if there's any abvious damage. Just before the ignition switch, blue also branches off to the speedo/tacho illumination bulbs so you could possibly learn more about exactly where the fault lies depending on if these light up at headlamp switch POS or ON.
I think this section of the wiring is also the same on bikes running the 3MB CDI unit even though the connectors from the loom to the CDI are different. Hope this helps!

Thanks for the help, but I'm pretty sure that on these diagrams a wire branches off to another when there is a black point at the connection, so if one wire crosses another wire but there is no black point at the connection than they're not supposed to connect, and the diagram makes it like this so the diagram can be small. I haven't seen this diagram but if my theory with the black points are correct then the POS isn't supposed to turn on the small bulb as there is no connection with the left handlebar switch, only the main switch (for the stop/aux light which is working on my bike). My question is if the pos isn't connected to the small bulb, and neither to the main bulb, then what is it supposed to do/why is it there?
