testing the fan

[Speedster450r]

I was wondering if there was a way to test the fan. my fan used to run all the time and it doesnt now. i have power to the fan. any tips?

Do you have a voltmeter? How many volts are you getting at the fan?
What happens if you take the wire off the temp sensor and touch it to the motor while it is running?

where do u guys usually ground the fan at ? i grounded mine at the coil , it tht a bad spot ?

Any bare metal spot on frame or motor will do fine.

Behind the coil is a good place to ground to if you have enough wire. the fan circuit is pretty simple. On the 04-05 bikes, some people would take apart the key switch and turn it in its housing so that it didn't matter which way the key was turned, the bike would still start. The problem with that is the fan doesn't work anymore. If that is not the case and the fan relay is not messed up, and nothing else has changed, it is probably the fan motor that is out.
