Dong Fang DF 250 RTB Bobber Information

**GUN ROD** · 10-28-2011, 12:03 PM

Searching for my headlamp problem, I ran into this mystery component, green line connected behind and an open tab with nothing connected. Right side of photo is a blue/white and a yellow going into a connection but other side nothing. The mystery component is under the left side of your tank, can any one see what wires are connected to yours

Any ideas?Mysty.jpg

Bad photo but I removed the box and saw a red wire and two green wires attached.
It's a diode bridge circuit that converts ac to dc and in that application is called a bridge rectifier. I'll call it a black box.
The label on my black box is faded but I think the manufacture is ZINZEN. Can you read yours?
You might have to remove the black box to see the wires.

It's 40 amp and 1600 volt so it can handle a lot of juice.

BTW, My head light is working with the engine off and the illuminating switch to the headlight position(all the way to the left)

When you swapped out the handle bars did you take the illuminating switch apart? That feeds the headlight.

This photo shows the Blue/White wire connection that I had somehow pulled part perhaps when I removed the tank.

Barnone, thank you you have gone to allot of trouble, to answer.
Behind the black box, you found two green (right side?) & one red (left) I need to find that red lead ( I haven't cut the holding ties yet)
Will open both & look.

Regarding Blue/white & yellow (my picture) with no wire connected other end, what was yours connected to?
Wait look at your first photo, same as mine (just above the tie rod) it's the same, dead ends, other end heat wrapped & no further wiring, right?
I have not disassembled Illuminating switch other than screws to open for new bars. Tempted due to diagram showing allot of related wires to my issue. I've been concentrating on left Dimmer.

Plenty of time on my hands since it's raining here so no riding today and gonna get cold with a freeze forecast. We are heading to Florida next Saturday or Sunday.

The red and the two green wires come out of the same bundle so should be easy to find the red.

Two green left side and red right rear. Nothing on the other lug.

Barnone, my wires on the black box are reverse, red & open lug forward, 2 greens rear.
Xinzen MDQ40 /1600V on the cover with a wire diagram
If your red was rear was the open/unused lug as well (rear) ?wires.jpg

The red was rear next to the open lug. Looks like yours is wired the same as mine and the box just turned over. The two greens are definitely the same as mine. This bridge rectifier should have nothing to do with the head light.
