I was out riding my 9S yesterday and the red check engine light come on for no apparent reason. The motor also started to miss over 3K RPM. I drove over to a friend's house and noticed that the fan didn't come on when I stopped. I checked the fan fuse and it was blown. I checked for continuity to ground and couldn't find any and then checked that the fan blade was free to turn. Everything looked OK so I put the spare fuse in and headed for home. Everything ran fine until I got close to home when the light came on again and the engine started to miss. I got home and sure enough the fuse was blown again. This time I checked the wires very closely using a droplight and noticed that the fan's hot lead had a break in the insulation. I pulled the rear shock and then the fan and saw that the wire's insulation (yellow/brown trace) was abraded away down to the copper wire by a sharp edge on the rocker cover. I guess a bump in the road made it occasionally touch and short out. No biggie to fix. I put some cloth electrical tape on the abraded spot and wrapped the whole cable with spiral wrap. I also wire tied the cable to the frame so it can't get close to the head again. I suppose the engine management system makes the engine miss if the check engine light is on to keep the revs down. I suggest you all take a look at the fan electrical plug and make sure its not right next to the head. Steve | ||

thanks steve, i had the same mishap last year, ( i was running o,5 sort in oil as well  on very hot day ) i have put some exstra spare fuses in my tool pack i looked at the wire's but no ware marks here, i blame the fan motor pulling a spike amp while starting ?? ( it didn't run for a while ) gr,B | ||

Steve, I had exactly the same problem last summer. My 10 minute fix was identical to yours. Thanks for the info. | ||
| Bud |
i had to check it again,  good thing that i did, gr,b | ||

Bud, That is EXACTLY what mine looked like. I hope folks are reading this thread. Steve | ||

Thanks for the heads-up. I'll definitely check that out in a few hours when I get home from work. You may have just saved me (and most likely some others, too) a severe headache.  Thanks again. Mike. | ||

Thanks for the info! I'll be sure to check mine too. Damn I love this board...I get this time of heads up anywhere else! With my limited mechanical abilities, I may have gone off the deep end. Probably would have taken the local dealer a week and who knows how much $ to fix! Thanks again for the headache relief! | ||

Whew! Mine appears to be safe. I didn't take the shock out or anything, but from the looks of it my XB9R fan wiring is tied back at the bottom of the fan shroud and there is nowhere near enough slack there to allow it to come close to the head. Bud, your pic of the connector shows the connector that's plugged directly into the back of the fan, correct? Just want to double-check in case I was looking for the wrong thing. Mike. | ||

about 3" off wire between the connector and the fan if you lift your airbox cover, you should see him trough the gap in the frame ( left side ) gr,b | ||

Got it! I also took a look at that section of the wire last night. No abrasion on mine. It's tucked back pretty tight, but probably worth tying back just to be safe. Thanks. Mike. |
