Looking for pinout info on an 2 stroke CDI module. It has two wires in a two-pin plug (black and orange) and 3 loose wires with amp-style connectors (white/red stripe, black/red stripe, black/white stripe). A previous mechanic cut the CDI jack off the bike I'm working on and installed a 4-stroke CDI module, and the 4-stroke CDI is sufficiently *off* so the bike won't run properly. The bike idles great, but acts like the turn signal flasher is controlling the ignition switch at top speed! (Run for a second, dead for a second, run for a second, dead for a second, just like a clock.) Other than that- I'm at a loss for what's wrong. The carb was jetted wrong (fixed) and the fuel pump was bad (fixed). Now just the flaky ignition when the bike is running at-speed, and all will be good to go. I need to splice the above-mentioned CDI module into the wiring harness (I already know the harness pinout), but this aftermarket CDI module came with no wiring diagram, so I'm stuck. The original jack was cut off by the prior mechanic, so no way to just plug in the proper CDI module. (I don't have a jack to use to remanufacture the wiring harness.) The bike is a Benelli x50i, and the harness wiring appears to use standard color coding. The 2 stroke CDI module I have has wires hanging out with no molded-in jack. The reseller does not have a wiring diagram for it, referring me to "search the internet" for it, and searching the internet produced no results. Here's a link to the CDI module I need the pinout for: www.partsforscooters.com/50cc-2-stroke-CDIOn the box it says simply NF50 and a bunch of Chinese writing. Thanks if anyone can help, Eagle Rider MB |

Have you asked the vendor?

Yep- they're the ones who referred me to "search the internet" (quoted above from original post). No help at all. Link is in original post to vendor's website for informational purposes. Thanks, Eagle Rider MB |

As it turns out - I had another Benelli on the repair floor, and tried the CDI module out from it. The original CDI must be OK, so I'll have to look elsewhere for the problem. I'd still like to know how to wire these aftermarket CDI modules, however, in case I ever need one! Thanks, Eagle Rider MB

Can you reverse check it . I would imagine 2wires go to the coil , 2 wires to the cdi one pulse the other power . Post a pic of the stator plug connection . Ground so far we have covered 5 wires just need the colors . We could make a diagram together . Then I could sell them and offer tech help .
John
Ok one to the coil , one kill wire , one pulse , one power and ground . As a guess black/red is power from the stator white/red pulse .
Feel free to fill in the blanks .

Ok one to the coil , one kill wire , one pulse , one power and ground . As a guess black/red is power from the stator white/red pulse . Feel free to fill in the blanks . Adding another guess I`d think orange=coil, black=ground, black/white=kill. There`s a 2 stroke wiring diagram which seems to illustrate a 5 connector cdi. A couple of the colours are different but the black does seem to tie in with earth, and seems to be on a 2 connector plug with the coil wire which would point to the orange being coil. Black red, red/white seem to tie in with stator wires. Of the remaining black/white one (which is dark green in the diagram), it seems to go to an alarm system which would point to some kind of kill wire. Diagram is here scooterdoc.proboards.com/index.cgi?board=wiringdiagrams&action=display&thread=5389 |

Sorry for the delay- busy this time of year!
Wires on the CDI are:
IN MALE 2-pin PLUG: Orange and Black (coil and ground)
Black with Red Stripe male AMP connector (probably stator power in)
Black with White Stripe female AMP connector (?) (kill?)
White with Red Stripe (?) (will assume pulse)
Can't find a reasonable (key word) CDI module for the E-ton Beamer III (the target
bike) and customer has agreed to allow me to experiment on his bike with this unlabelled
CDI module. If this works, will let everyone know. Bike is supposed to show up tomorrow.
Thanks for everyone's input. Eagle Rider MB
