  2. Well after replacing the Ignition coil I still didn't have pulse for spark. I bought a DVA adapter for my multimeter and checked the stator circuit going to the CDI. The CDI had signal coming in, power, and ground. So the CDI was presumably bad. I went ahead and replaced it and got spark back. She's been sitting for who knows how many years but now she runs!
  3. Haha thanks! I dug into it this afternoon. Looks like the secondary circuit on the coil is open so I ordered one of those first. The CDI box is interested though, I'm not getting a "positive" pulse from it to the coil. I see a ground pulse though. Isn't the CDI supposed to send a 12v signal? The shop manual didn't offer much insight on how the circuit works lol
  4. Thanks for uploading these manuals!
  5. Working on this right now. I will figure it out soon enough but I figured I would ask in here in case someone has a suggestion. I just purchased a 2005 Bruin 250 2wd. It has no spark. They replacement the stator and the ignition switch. Is the CDI box a common failure on these machines?
  6. Only need 2 more posts to unlock the cheat code...lmao
  7. Anyone ever use a universal lawnmower seat to bolt onto the rear rack on an ATV for a passenger? I have an 2005 Bruin but I have yet to see a seat for it other than those uber expensive helmet box/seats.
  8. Was tired of removing the deck on my lawnmower every time I wanted to drag something out the the woods and back. So I figured I would by a quad as more of a utility vehicle.
  9. Hello all, I registered on this site because I just purchased a new to me 2005 Yamaha Bruin 250 2wd. This seems to be the only place to get diagrams so I'm hoping I can download them sooner or later. The guy I bought it from said it had no spark. And it truly does not have spark...lol I haven't looked into much on it. Looks like he replaced the ignition switch and the stator. I'm thinking CDI box but I want to check the coil first. I look forward to helping others out on the electrical end of the world. I am an ASE certified automotive electrical technician. If it's 12v, I can usually figure it out.
  10. Nice! The guy I bought it from seemed to have just thrown parts at it hoping to fix it. I just need to get a wiring diagram so I can actually diagnose the problem.
  11. Shamelessly using this thread to add to my post count as well....lol I have a 2005 Yamaha Bruin with no spark. Hoping once I get my post count up, I can have someone help figure out what is wrong with it.
