49cc 50cc Unrestricted CDI Chinese Brand Automatic Scooter 6 Pin Plug 2 & 4

49cc 50cc Unrestricted CDI Chinese Brand Automatic Scooter 6 Pin Plug 2 & 4 Description

AC or DC?
This one is a AC CDI
Most CDI's are AC for scooters and buggies
If yours is working try disconnecting your battery, if your engine dies you have a DC CDI system. With an AC CDI it will continue to run.
Most CDI's with large bodies tend to be DC / CDI's with a body like a small matchbox tend to be AC
You can also tell by the wiring, if you have 3 or 4 wires going into the four plug that doesn't make much difference, but if you have 2 wires going into the 2 plug this is likely to be a DC CDI / 1 wire going into the 2 plug means it is likely to be an AC CDI.
Beware there are anomalies to these rules but most CDI's follow these rules

Check your terminals on your plug connector carefully as this is a type 2 unit. There is a Type 1 that has a single 6 pin plug.

The CDI controls the spark rate to the spark plug, and so can have a dramatic effect upon performance. If your machine is hard to start, missing a beat, not revving out fully, making a popping sound or, at worse, banging sound, you may need a new one. CDIs are also responsible for a complete loss of spark at the plug.

This part will definitely fit:

• Any bike that uses a 139QMA or 139QMB engine with a suitable wiring loom

Many Chinese brand and UK branded scooters use this part, here are just a few.
