ok after poking around a bit more under the seat I noticed that the 10a Terminal fuse is missing. Not sure if this is important but thought it was worth mentioning. Also there is a small fuse box that the positive battery cable runs into that has two fuse slots. There is only one fuse in this box, should there be two?

 

my grizz had the same problem with the brakes. I bled them and got quite a bit of air out, but after that it didn't make the noise anymore.
