Re: motobecane CDI ignition le partie - ground confusion

I noticed that the new version of the cdi wiring looks like both the black and black/white wires go together, is that so? Now I went from one confusion to another it looks like both wires go together. I don't want to take a chance and burn something

Re: motobecane CDI ignition le partie - ground confusion

Yep, can confirm. Just installed this last month, runs great off of cheetahs diagram.

Re: motobecane CDI ignition le partie - ground confusion

Cheetahs diagram is spot on, only debatable part is the exciter coil wire for the coil - should is be floating or run to common... the jury is out on that subject... either method will produce a robust and consistent spark.

If you follow the diagram and still no joy for a snappy blue spark then swap the orange and black wires at the coil.

Re: motobecane CDI ignition le partie - ground confusion

What happened to the diagram?

Re: motobecane CDI ignition le partie - ground confusion

Does this mean the current coming out the CDI is AC ?

I don't see a rectifier used for the current going to the lights.

Re: motobecane CDI ignition le partie - ground confusion

yeah these are AC out of the box, you have to rectify for DC

Re: motobecane CDI ignition le partie - ground confusion

Got my 40T running nicely with the le partie CDI, but have yet to wire up the lights— which voltage regulator should I buy?? What do you guys run?

The 12v trail tech dial a brightness is the best.

That's just a regulator though right? Not a regulator/rectifier. My understanding is you're still getting AC with that, just regulated.

I've been rocking these cheap amazon $9 ones, they seem fine.

Wired as such: https://www.mopedarmy.com/wiki/NU50M_Full_Wave_Rectifer

In the drawing there 1 is out to lights, 2 and 3 are input from your coil (just split the wire and hook to both leads on the regulator/rectifier), and 4 is ground. Has worked well for my LED conversions. Blasted a bunch of hot glue in it to keep the wires from falling off. I'm sure there's a better plug or something you could get, but whatev. (edited)

The trailtech is much easier to wire in anywhere in the circuit(like on the forks behind headlight).

Yes it's regulated AC...that's what you want unless you're needing DC for like, a water pump or phone charger.

Re: motobecane CDI ignition le partie - ground confusion

Thank you! Gonna nab one and throw it on.

Re: motobecane CDI ignition le partie - ground confusion

On swinging engines, I always ground to frame with a big ol battery style fatty gauge ground strap. It’s stopped any grounding issues, some people love their floating grounds I’ve just never seen the need

DC is better for LED lights too. Some will work fine with AC (rectified or not) but LEDs are fundamentally one-way devices, and you'll have more stable and brighter lights with DC.

Re: motobecane CDI ignition le partie - ground confusion

What's that thing in the bottom left of cheetah's diagram. Is that the headlight?

AC is a garbage waveform

All my homies send it to 0hz
