Carbide 150 GY6 No Spark By ipapilot (Read 8,185 times)

I'm pretty sure mine has the wrapped pole, but it is not used. The red/black wire is not attached to anything and I verified that with the manufacturer. Regardless, the blue pickup lead should still see something when cranking.. Even in an AC system it provides the signal to the CDI. So why in the world is there still no signal

[ipapilot]

I verified the old coil and new coil are the same. Neither used the red/black wire to power the cdi; just the blue for the pickup. Just for the heck of it, I changed the pickup wire to the old one to see if it made any difference and there is still no voltage on the blue wire when cranking. My understanding is there should be at least .4Vac to signal the cdi to fire. I also spoke with the vendor that supplied the stator and pickup and they are sending another one in case mine is bad.

When the pickup and flywheel are not installed, with a probe grounded to the flywheel, you can get a reading from the signal wire if you just move the pickup back and forth across the magnet. It seems that once it is installed it won't do the same... I'm lost...

What is the clearance when installed?,,,, too far apart?

[ipapilot]

I have a very non technical answer, but it is Very close:) Much closer and more consistent certainly than me just moving the coil back and forth across the magnet.

Did you also get a new flywheel or are you using the one that was on there. Reason I ask is if you got the wrong one the Magnet on the outside that triggers the Pick Up Coil may be in a different position than the original.



And here is a DC STATOR NOTICE ONLY ONE WIRE THE BLUE FROM THE PICK UP COIL and no POLES ARE WRAPPED which feed the CDI.

I purchased a new flywheel as well with the new stator. I definitely see the difference in the stators, but the issue seems to be with the pickup and flywheel. This is a wag, but even if there was no stator installed, wouldn't the pickup receive the same sort of input from the flywheel?

[cyborg]

Yes it would but if the magnet in the wrong position maybe it's firing but not at the right time ,, pull the plug and put the plug in the cap ground it on the engine and turn it over,,,, get anything at all?? Did you check the engine to chassis ground?

[ipapilot]

No spark at all... And the engine is grounded to the frame and I verified the continuity of the wire.

[Alleyoop]

Since you also got a new Flywheel, is the PICK UP COIL MAGNET in the same position on both in relation to the WOODRUFF KEY?

If so try a new Pickup Coil.

[ipapilot]

Magnet is in the same place on both flywheels in relation to the woodruff key.. Have installed both the old and new pickup with the same results (or lack of).

[Alleyoop]

So only two things then stator is crapola and or the pickup is crapola only those two things since no juice is coming from the pickup coil, one or both are bad.

[ipapilot]

I'm with you on the pickup possibly being bad. Hard to believe both the old one and the new one are bad though. The vendor is sending out another pickup and stator as a warranty replacement just in case.

Would it be correct to assume that the stator itself though is not playing a part in the signal to the pickup coil? That is just a function of the flywheel and pickup sending a signal through the blue wire to the cdi right?

[Alleyoop]

That is correct the only thing that activates and builds the low voltage inside the windings of the pickup coil is the MAGNET just like the other poles on the stator that pass over 8 magnets built inside the flywheel and produce Voltage AC.
So for no voltage from the pick up I would just get a new pick up coil, they are cheap.

[ipapilot]

Let's keep our fingers crossed, a new one is on the way!

[Alleyoop]

Good luck and hope that is all it is.
