Yamaha 1997 Big Bear CDI Pin out

[reprob]

Im new to the group and hope to find some help here. I have a 1997 Yamaha Big Bear 4x4. I am having ignition issues. I have checked all switches to the CDI box and all check out. I Replaced The pick up coil and stator, as the pick up coil was open, no continuity. My problem is I can't find a schematic that matches what I have. My CDI has 2 plugs one 4 pin with 3 wires going to it, and the other is an 8 pin with 7wires going to it. I have traced all but one it is solid blue on the 8 pin plug. I have no idea where it disappears to with out tearing apart the harness. Any ideas as to what this wire goes to? A pin out of the cdi would be helpful, The number on it is F8T32372. Any other ideas before I try and find a new CDI. Thanks for any help. Robert

Hi, Did you still need help with your Big Bear?  Sorry to hear about your ignition problems.  Did you download the service manual for your machine?  Not sure of your engine size, this might help:

You'll need 10 posts on here before you can download, I might be able to help with that if needed.....:o)

Let me know if I can further assist - Cheers!~  Bellarmine

Have a look here and see if you can identify your model..  Partzilla will tell you what any part you choose will also fit.. Look the part up, choose the part like you are going to buy it, and they will take you to a new page where it tells you what other models that wiring fits. If your wiring fits some other model, then the other model wiring will fit your bike. You can check their opinion by doing the same process in the other site.
