Reaserched couldnt find help.. No spark By 2001eton (Read 4,264 times)

[2001eton]

It always ran with out a battery tho i had it started and running with out a battery

[Alleyoop]

Well then IF YOU DID NOT CHANGE ANYTHING and it was running and then QUITE then one of the following went bad.
1. plug
2. Boot Cap
3. COil wire
4. COIL
5. CDI
6. Pick up COil
7. Stator feeding the CDI (cause no battery)
8. Ground motor to frame
9. Killswitch is grounding out the CDI.

Don't know what else to tell you.

And that is it for a NO SPARK

[2001eton]

Whats the diffrence to between the coil nd pick up coil... The stator could still be bad but also provide power at the same time?

[Alleyoop]

Here is a 2 stroke STATOR with Points to tell the CDI when to release the voltage to the coil.


Here is a gy6 STATOR with a PICK UP COIL to tell the CDI when to release the voltage to the coil.



Here is the COIL and WIRE that goes on the SPARK PLUG.

[2001eton]

But can the stator be bad and still turn the dash light on and off while kicking it

[Alleyoop]

The stator does a few things:
1. Feeds the CDI IF it is a AC CDI.
2. Feeds the Regulator/Rectifier which in turn charges your battery and some lights.

So yes it could be bad.

But you need to find out which kind of stator you have? If you have a PICK UP COIL that sends a signal to the CDI to fire you need to test that and see if it registers .25 -2.5 VAC if so it is good if less than .25VAC the pick up coil is bad.

[2001eton]

And i test that by using the blue/yellow that runs from the stator to cdi?
I was also told to test the cdi.. I i leave the stator wire and the ignition coil wire in the cdi and connect the positive of the batt charger To the cdi positive and and the negative To the cdi negative

[Alleyoop]

NO NO NO, you CANNOT USE A BATTERY CHARGER to test things. YOU NEED A MULTI METER like this:
BATTERY CHARGER is to charge a battery.

[2001eton]

I have one of those but this is what i was told too

[Alleyoop]

So what do you want from me I also said to test the Pick Up coil(TRIGGER WIRE) which is what whoever told you is also telling you and notice he also said to use a mulit meter.

The only thing I would not do is try and power the CDI with a Battery Charger to much juice will blow the CDI, which by the way may have been already done due to using a battery charger.

[2001eton]

So test the trigger wire with ac voltage? Or dc voltage?... Ima just do both and post the results

[Alleyoop]

ALL VOLTAGE FROM THE STATOR IS AC , the R/R that charges your battery turns the AC TO DC to charge the battery and the battery powered stuff is DC.

SO SET THE MULTI METER TO VAC

[2001eton]

Im reading about. .6 on ac nd negative something on dc

[2001eton]

When i put the multi meter to the orange wire.. And hit the kill swich. It jumps all over on dc voltage

[Alleyoop]

.25 and higher reading is ok on the pick up coil wire.

The orange wire since you do not have a battery and the motor is not running should not have power
