Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all.

Well got another one for the elders here. I recently picked up a Honda Trx 250
in pretty rough shape. Brought it home cleaned it up if thats possible. Motor was
seized, Pretty bad shape. I unseized the motor, got it to spin over, Got it to crank on its
own with the start button. Got neutral light, but no spark. Fuses good wiring is old but looks
intact. Went to check cdi box, here is where the problem lies, I dont know the year. The last one
was under the plastic on the crossmember, this one has none. Looks like a sticker was there at one time.
I checked the left side of frame by foot peg and nothing. Cant find any vin number. I need to know the year
to try to locate a cdi. One clue is this one appears to have 2 cdi boxes. One is a little larger than the other but
plugs look identical to eachother. One has green connectors and the other has white connectors. Is this only
on certain year model that has duel cdi boxes? I also need a download for a trx 250 Im thinking its about a 1985 or 86
but just a guess. Before changing i would like to check some voltages but need a manual for this. Any guess on how to
identify and or get a download for this one would be great. Wont let me post pics only .08 MB Down load available. Thanks in advance Az
Hello guys! New to the forum, and fairly new to ATVs. I've driven them, but never owned one. Now I do own one. Just picked it up today. It's a 1999 Yamaha Big Bear 350. It's been through some stuff. The guy I got it from told me the previous owner removed the front diff because he didn't want to replace the half shaft. So it's 2wd, even though it's supposed to be 4x4. Lovely. I can deal with that for now.
More importantly, I need to get it running. The carb needs to be rebuilt. The guy I got it from said he sprayed it all out and it still didn't work. I'm concerned he might have damaged it or not put all the parts back. I was looking at a replacement carb, and the OEM parts is $600. I'd rather not spend $600 if there are any other options. I have seen carbs on Amazon and eBay that are in the $40 - $100 range that say they fit. Anyone have experience with these? I'm going to get a rebuild kit for the current carb just to make sure that won't fix it.
Thats the first thing with it. Secondly, it was completely rewired. I need to find a original wiring diagram so I can put it back how it was, with a key and all. Currently it's wired with just a rocker switch. Any sources for a service manual that would include wiring diagrams?
Thirdly, is the Big Bear 350 a good atv? I picked it up for $700. It does start and run when you spray starting fluid into the air intake, so I am not concerned about the engine being bad. I plan to use it for the farm, running around and carrying things with it like minerals and feed and such. Not really for mudding and things like that. How good is the 99 350?
I am certain I will have more questions as I examine it more, but that's all for now. Thanks in advance for the assistance!
