    Question G0704 Motor/Controller problems

    I have a relatively new (May2015) G0704 and recently purchased/installed a Benchtop Precision belt drive conversion kit. The motor/controller has humming/buzzing noise and just now blows fuses. I'm not sure what is causing this and have no idea of where to start looking.

    Anyone had experience with this? Thoughts? Solutions?

    if it is that new, call Grizzly tech support.I have several Grizzly machines and have called them a few times and they have always been very helpful.

    As it turned out, Grizzly tech support were very helpful in diagnosing that the motor is bad. With both the included fuses blown I had to hunt down fuses which turned out to be expensive $1.80 each and hard to find. Anyone with a G0704 might want to get some spare fuses. The controller is a simple variable voltage unit so was easy to test with a multi-meter. They are going to supply a replacement motor on warrantee. They are waiting for a shipment of parts due in August so I just have to wait for it to arrive. Waiting will be the hardest part.
