hibird 6 pin CDI 250cc help
i have this 2008 hibird atv. i got it running a while back, and havent touched it since( few months) i come back into it find that the started solonoid is stuck, i took off a few wires the previous owner ghetto wired on the atv and now i have no spark, engine turns over and everything just nothing from the spark plug
my question is does any one have a wire diagram i can work off, from another atv similar to mine
i believe i have to 2 pin wire on the CDI wired wrong

I assume you have the generic 6 pin CDI (2 pin and 4 pin connectors). Is this correct? They come in two flavors - DC powered and AC powered. Do you know which you have? (You cannot tell by looking - if you don't know we will need to do some measurements with a meter to find out. I'll attach the procedure at the end of this post.
Once we know which CDI you have then further testing will be required using the generic AC procedure, or the generic DC procedure. That should point us in the right direction.

The 2 plug 6 wire CDIs come in two different designs. One is powered off 12 volts DC, and the other is powered off a moderately high voltage AC which comes from the stator. Unfortunately there is no reliable way to tell the difference between the two by just looking at them. To be sure you need to use a meter to find out which you have:
1) Unplug the CDI, and turn on the ignition. Do not crank the starter motor. Use a meter to measure the *DC* voltage on the pin labeled "AC ignition power" in the wiring harness to both ground pins in the 4 pin CDI connector. If you measure 12 volts DC then you have a DC powered CDI.
2) If you don't measure 12 volts DC on the ignition power pin, then switch the meter over to measure AC volts on the 200 volt scale. While cranking the starter motor, measure the AC voltage on the "AC Ignition Power" pin to the the Ground pin. You should see 40 to 80 volts AC. If you measure AC voltage when the starter is turning then you have an AC powered CDI.
Using a meter is the only 100% reliable way to figure out if your CDI is AC or DC powered. But there are some clues you can use that are usually (but not always) correct:
A) DC CDIs tend to be a little larger than their AC powered counterpart. This is because the DC powered CDI needs a bunch more circuitry to convert the 12 volts DC to the moderately high voltage supply that all CDIs must have.
B) Most (but not all) DC powered quad ignition systems do not use the kill switch input pin. The CDI connector pin usually has no wire tied to it. AC powered quad ignition systems usually do use the kill switch input pin.
