 Introduction:
This is a high performance racing CDI for the GY6 50cc, 125cc, and 150cc 139QMB, 152QMI and 157QMJ based engines.  
It's 6pins, this CDI works with the GY6 type plug on it, with an AC ignition system.
This CDI is similar to our orange performance CDI but has a more aggressive ignition advance curve. 
This is a performance CDI. We have the best quality ignition parts for Chinese engines!
This is a AC FIRED System CDI.
Plug and Play installation makes installation a breeze! 
If your CDI has the same plug, this will work for you!
 Ignition coil Feature:
High tension performance racing ignition coil for 50cc QMB139 
Iand 150cc/125cc GY6 engine based scooters, ATVs, Go Karts, Mopeds.
 
This coil can improve combustion efficiency, strengthen electrical performance. 
Boost your ignition spark intensity considerably. Eliminate spark plug fouling, 
decrease hard starting, increase acceleration, increase fuel mileage and decrease
hesitation 5-10% boost in acceleration and top speed

The spark plug cap is removable, just twist it off and can be use on any other different degree spark plug caps.
 Use a multimeter:
Primary resistance test, attach both positive multimeter lead and negative multimeter lead on the primary sides(input sides of the ignition coil).

Secondary resistance test, negative lead on the output side(wire without the spark plug cap)
and positive lead on the primary sides (both primary sides should get the same reading on the multimeter). 

Now you can twist the spark plug cap(or your old cap) back on(tightly) to do the secondary resistance test again.
It should add another 5-10k ohms to the reading.
 Note:
Please check whether you need the AC fired CDI or DC fired CDI for your scooter before you order it ,thanks.  
 How to distinguish CDI box with AC fired or CDI box with DC fired?
1. In the GY6 6-plug set-up. You have AC if you have 3-wires going into the 4-plug  
side and 2-wires going into the 2-plug side. On the other hand, you have DC if you
have the larger CDI box, 3 or 4 wires going into the 4-plug side and only 1-wire 
going into the 2-plug side. 

2. If headlights turn on without the engine running(with just the key on), it is a DC system. 
In the AC system, turning  headlights on require the engine to be running. 
Another indication is, if the engine will only runs with a battery it is DC. 
If it will runs without a battery, it is a AC system.
