Hey guys, got the atv all put back together today, everything is all nice and tight. We out the original engine back on it because the other engine needs a radiator. So we switched motors back, and the thing wont start, its not getting any spark at all... Anyone have any ideas? Or a manual/ wiring diagram for this kinda of atv? Please help!

 

Anyone? Ideas? Help lol

 

 

Well, i out the stock 150cc back on, its the 300cc that the kid had on there that needs a radiator, which is why i switched back. But the kid i got it from said it ran before he swaped the motors, (he wanted the bigger engine cause it had more power and reverse for plowing) So we swped motors back, made sure everything was tight, and everything was connected, and it just wouldn't start. so we checked and its getting gas for sure, just no spark. But i had no time to look at it today, so ill have to tomorrow. But when my dad was messing with it the other day im pretty sure the CDI was getting power in...

 

One of the confusing things about Kasea 150cc quads is what engine they use..

Is it a GY6 150cc with CVT transmission, or a non-classic engine with a geared transmission. When I look on the internet i see posts claiming both.

Still need info on the CDI...

 

Where can i find out what engine and stuff it is? Sorry new to atvs so learning as i go lol, and the CDI looks exactly like the one that you posted a image of in this thread

Gy6 engines use a (C)ontinuously (V)ariable (T)ransmission [CVT] driven by a belt. It is fully automatic. There may or may not be a reverse. If there is a reverse it is a gear box added on to the output shaft that drive the chain sprocket. If you google "GY6 engine" you'll get lots of pictures to look at.

Regardless of what engine, the fact that you have this CDI points the way to solving the 'no spark' problem:



These CDI's come in two versions: They can be powered from high voltage AC from the stator, or powered with 12 volts DC through the ignition switch. They look the same, but they are not interchangable.

To see what your quad is wired for (and therefore which CDI you need to use) unplug the CDI, then measure the voltage on the "AC ignition power" pin in the wiring harness (to ground) with the ignition switch on. If you have 12 volts DC your CDI is DC powered.

Switch your meter over to measure AC volts on the 100 to 200 volt scale. Measure the same pin while cranking the starter motor. If you have 50 to 80 volts AC on this pin then you have an AC powered CDI. This CDI is much more common, and the older the quad is the more more common it will be.

This is just the start. Once the kind of CDI is established, the next step is to measure the stator trigger voltage, kill switch wiring, ignition coil resistances. All of this is easy to do with a meter once we know which power version of CDI you have.

 

Well i have the manual transmission, so whatever engine that is. and im going to pick up a volt meter tomorrow, so that'll, have to wait. ill update once i get that

 

Then you dont have the GY6 engine.
