Fan mystery here. My last motor had a rod bearing go out, about when I stopped riding it due the knocking, the engine light came on. I didn't think too much about it because it was going to be down for a while. Fast forward a year, I've gotten a donor motor in now. Engine light still on, throwing the 36 code, which would be the fan. I thought ok, fans out not too big of a deal. Have taken it on a couple short rides anyway because I just can't help myself, shut it down and the fan comes on like normal afterwards, starting with high speed and going to low speed. It's definitely not coming on while riding. I would think if there's a short it would blow a fuse, which it hasn't. Any ideas? I sure do hate electrical problems. | ||

Your fan is probably on it's way out. Mine just went on my Uly after a 600 mile trip. Before the trip, it was intermittently not working and generated code 36, and during the trip it quit altogether. If you're using ECMspy, and your wiring is anything similiar to my '07 Uly, back-probing the #6 black and orange wire coming out of the ecm with a test light connected to battery positive while actuating the fan will let you know if the ecm is OK. If you're not blowing fuses, then obviously no shorts to ground. If you can easily access the fan connector, then unplug it and check the continuity between the connector, the ecm, and the fuse.

I wouldn't be surprised if the fan was going out, over 40k on the odometer right now. It's just weird to me because when I shut down the fan comes on strong, no rattling or excess noise, no varying rpms. I don't have ecm spy anymore, the laptop I had it on took a dump. I used the trouble code dongle from American Sport Bike to get the 36 code. I was thinking maybe the heat sensor is out, not telling the ecm that motor is hot enough to run the fan, but seeing as how the light came on with the old motor, I'd have a hard time believing they've both got bad heat sensors. I'd really prefer it be one of those so could just replace it and be on my way. Did I mention I hate electrical problems? Bad at chasing those gremlins... | ||

I had a cylinder head temperature sensor come loose 5 years ago. Guess and by golly, thinking a bad sensor, I replaced it, curing that intermittent problem. About a year later, motor oil dripping from the air box into the fan caused debris to stick to the fan, causing the fan to stick and blow fuses. |
