I dropped my bike on the left side last summer; the fall pushed the fan into the radiator slightly. No big deal, I straightened it using a tire iron and all was good until I rode it his summer. It showed a hot code and I stopped to let it cool off. I took it home and checked it out as follows;
The fuse for the fan was blown. I replaced the fuse and started the engine, letting it idle as I watched the temp guage. The fan stayed off until it got to 220 degrees F; the fan came on ( spinning freely) for about 5 seconds, then the fan stopped. It had blown another fuze. It continued to idle until it reached 240 degrees F, then the hot message showed up on the screen ( I turned it off).
I didn't loose any fluid during that test. I connected the fan wires directly to the fan and it runs freely ( I let it run for 3-4 minutes).
I then checked the thermostat by putting it in a pan of water; as it heated up, the stat opened up at about 160 degrees, then closed when the water cooled down
I pulled the water pump and the impellor spins ( slightly firm to spin). Everything there seems fine.
I replaced the fuse and reassembled everything. Started It up and the fan didn't come on until 220 degrees, then blew another fuse about 5 seconds later. Same as before........
The fan seems fine. The only thing that I can see is the " fan motor relay" must be causing the problem.
Thank you in advance for your thoughts.
