So i recently acquired an 07 400 auto, paid $1000 and only has 900 miles on it, the thing is in fabulous condition, unfortunately it has had a good bit of work done to it, and everyone loves picking up on an unfinished project. So here is what i've got, it supposedly has a new stator in it (looks like it does), it came with two more, one is worn out, like the tops are smooth, and the other one looks used, but the flywheel is not harmed. it came with a new cdi box (Procom PE-C-AS/K400-A) not sure if this is compatible or not, but when i plugged it up, i think it may have blown the ign fuse. it came with a new (UP2) voltage regulator. and the spark plug coil is not stock, have the old broken ones, everything works but no spark, it has an new aftermarket left handle switch cluster, also have the old one, and i don't know if it is supposed to have more, but there is only one diod in the fuse box, i have a wiring diagram, as well as all of the manuals.
Another 07 400 with no spark!?!

I live about 30 minutes away from a atv junk yard, so if i can't figure it out, i will just take a day and start swapping stuff untillllllllllllllllllllllllllllllllll it works, PS. if you had a 00 polaris 500, and an 07 cat 400, which one would you keep? so far the polaris is winning, cause i've fixed it, but just curios?

You’ve got a mishmash of parts that we have no idea what they are. Do you even know whether stator is OEM or aftermarket? Some AM ones needed wires reversed for spark. Even though it’s an 07 it may have had the old style magneto in it with early production.
Yes I have tried, swapping the wires, he bought OEM and China, I have read all the conversations about 400s on this forum, my stator/magneto tests fine accept for voltage the green and blue wires on the four pronged plug, which are said to be magneto trigger wire? One blue/- green/+, and the book says it should be over 5 volts, but is that when it's running, starting, sitting? I get a slight change in volts when turning it over, like .5 .7 volts?
ok so here is what i have figured out, the book says that when the starter is turning over that i should have more that 5 DC volts from the blue and green trigger wires coming from the magneto,i get maybe .7 at the most, is that an issue? when i test the stator i get 193 ohms, which is in speck.
SorryI. Not sure what vdc means, but my guess would be direct current voltage, then yes I'm only getting .5 or so from the green and blue wires coming from the magneto/stator, would that mean a new stator, or the stator and flywheel, or could I check the gap between the magnet and the flywheel? And should the the cdi bow be quietly buzzing?
Guess it’s not in such fantastic shape.
See what the junk year has to trade
Sorry couldn’t help it.
My in fantastic shape Yamaha has been waiting on a rear arm for two mo now just got an email update been pushed to the end of may now.
