I think I have a damaged CDI box. Here is the story. Last season I hooked up air horns running off a sealed lead acid rechargeable battery that was running off the electrical system of the sled, for recharging puproses. I had it running off (fused) the blue wire at the 4 pin harness under the seat. Towards the middle of the season, the air horns stopped working and battery wasnt charging, along with my heated hand grips and the tail light only illuminates very dimly now. I am assuming I may have damaged (overloaded) my CDI box being everything stopped working at once. I'm pretty sure there are no fuses or fusible links to repair, so I'm assuming the problem is in the CDI box. My question is, can an internal repair of the CDI box be done or has anybody had any success repairing these?? Or is it not worth it and just replace it? Thanks

I kid you not, Ive been thinking of installing air-horns on my sled also!! I hope that wasnt the cause of the CDI damage(if any). Sounds like you fried some wires together. Good luck!! ;)!
 
I don't believe you can repair the CDI box due to the encasement in epoxy. Also, if you had damaged your CDI box, your sled more than likely would run at all. Chances are you damaged your voltage regulator or your stator. ANybody else know if there is something else you need to put in the circuit if you put a battery on the charging system? I've seen them when looking for and srx cdi box on ebay. There aren't any on there right now so I can remember if you need it to put a battery on a yamaha or remove a battery from a yamaha.
 
I dont think it was the air horns themselves that did the damage. I had the air horns hooked up isolated from the sleds electrical system. The horns were working off the batteries (two 12v sealed lead acid ran in parrallel) I installed. I used the batteries so I could blow the horns with the sled not running. The horns are used as "motivation" to get the group back on their sleds after we take a break trailside. The batteries are what was hooked up to the sled. And I figured the circuit they were hooked to got overloaded or something. So do you think it is related to the voltage regulator or stator and NOT the CDI box?? The sled runs absolutely fine. Everything else, electrically, on the sled functions perfectly.
