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
I have a 99 250 Quadrunner. Currently has no spark. It would run for 5 minutes, then shut off. After it cooled down about 20-30 minutes, it would start again. I ordered a new stator and found the old one was damaged (copper windings broken) I installed the new stator, filled with oil and now it has no spark. Any assistance would be helpful

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.
I’m working on a Kawasaki Bayou KLF400 for a family member that doesn’t have spark. I’ve already replace the ignition switch and the stator which were defective. The stator had a melted connector and one of the phase had low resistance and low VAC output.
What I’ve figured out so far is that I’m not getting 12V to the ignition coil when I turn the key to the ON position. From what I understand, the 12V should come from the CDI. I’ve resistance tested both wires going from the CDI to the ignition coil (Green/white and black/yellow). They are fine. The only 12V coming from the ECU is on the yellow/red wire.
I don’t have the wiring diagram for the 400 but I’m working with the one for the Bayou 300 which looks pretty similar except for the wire color between the CDI and ignition coil. On the 300 diagram, the yellow/red wire goes to the ignition coil, not the black/yellow… All the other wires color match except for this one. Not sure if that’s normal?
