MOPED ARMY

Here is a photo taken from the front of the bike showing the alignment as best as I could. I'm using a Nikon D7100 DSLR for my photos and it will not focus at close range.

Happy New Year guys! Connecting wires today and am having a problem with the brake lights not working. All the individual wires in the wiring harness tested good for continuity. When applying 12V to the white magneto wire, I have headlight, tail light and speedo lights working but no brake lights with either lever. The tail light bulb is good. I tested each individual brake light switch and I had continuity between both wires ( on the throttle side black and yellow wires for example) when the plunger on the switch is depressed like when the lever is at rest and an open circuit when the plunger is out as when you squeeze the brake lever.

Does that sound correct? Seems weird to me that you would have continuity with the plunger depressed.

I believe I have the headlight switch installed correctly (as it was when I took it apart) and the wires hooked up to it properly. On the double terminal side of the switch, I have the white double wires to the headlight and the single white wire to the speedo lights. On the opposite side of the switch, I have the black wire to the ground in the rear and the white wire to the magneto on the front terminal.

I have included the wiring diagram for your reference. Anyone good with electrical will hopefully be able to tell me what is wrong or at least something to check out.

Thanks for your replies! (edited)

Maybe this will help :

Thanks guys, it seemed too simple to bother snapping a picture. I managed to install all of them incorrectly apparently. When I picked it up all the springs jettisoned in different directions. Found 4 of 5 so far.

BTW, sorry Bob, didn’t mean to jack you thread!

Horn and brake lights are fed from the other coil (brown lead) so putting power through the white lead won't energize the brake light. The horn needs to be in play, or at the very least you need to have violet/brown connection to energize that circuit.

This is how I found mine.

Thanks Mike, every thing is working now. I never thought that the brake lights would be fed from the 6V side. Like I said, wiring schematics and electrical aren't my strong point. The horn works, as crappy as it sounds, just an annoying buzz. While I was testing the horn circuit I squeezed the brake lever and I saw the brake light come on. Eureka! Headlight, speedo lights, tail lights all work on 12V and the horn and brake lights work on 6V.

The single white wire I have on the opposite side of the other white wires is for the speedo lights.

On to making cables for the carb and timing the engine are next on the agenda.

All the cables are installed and working. I used the Puch cable party pack from Treats and modifications were required to every cable for proper fit and function. I will have to admit that of all the throttle assemblies I have worked with over the years, the Motobecane throttle assy. is pretty wonky and doesn't return to the off position as smoothly as I would like. I may have to do some cable placement adjustments or something to get the throttle to snap back to the closed position better. Seems the spring in the Dellorto 15 could be a little stronger.

I did have to do some slight modifications to the throttle slide to accept the small end of the throttle cable. I used a small carbide rounded end bit to open the area in the slide for the cable to stand up and exit straight out the top as it should. I also placed a thin O-ring in the carb mount where it contacts the Malossi intake manifold to prevent any air leaks.

I also modified a cable bendy for the throttle side of the carb by using a plated brass 45 deg bendy from Treats and cutting off the cable receiver end, drilling it out and soldering it back on the threaded end after cutting it back and removing the plating where the cable receiver would go. Ended up with about a 10 degree offset for the throttle and a 45 degree bendy for the choke side.

Next project will be timing the engine. (edited)
