Hello I,ve seen there was discussion about CDI boxes what they was for example, but I was wondering if a CDI box off of an 2008 Polaris Outlaw 525 will work on my 05 Predator 500, it has the same plug in, thanks to anyone that could help

I recently acquired a non-running 1989 Big Bear. PO told me it would need a carburetor. I tinkered with the fuel system enough to get it running and drove it around enough to ensure the drive train was working (probably 1.5 - 2 miles). A few minutes later I attempted to start it to move it back into the garage and it wouldn't fire. Checked for spark at the plug (wire held close to block) and no spark. After getting it back into the garage and checking a few things I concluded it was likely a bad CDI box. I went on line found an aftermarket box that was advertised as compatible with an 89 Big Bear. When I installed the new box, the quad still would not run but each time I hit the started button I would get a single spark (turn key off and back on . . . hit the starter button . . . another single spark). When I got the new box I did note it was not identical to the old one(had an extra wire in one of the connectors). The part number on the box says it's a 1YW-85540-20-00. The box I took off the quad is marked 3HN-00. Which I understand after looking at a parts diagram likely means this is a 3HN-85540-00-00 CDI box. I reinstalled the old box and confirmed the quad has no spark with that box. My question now is whether this new box will work on this quad, given the apparent part number discrepancy, or do I just have another issue somewhere in the ignition system? Any insight would be much appreciated.

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
