With the drive assembly removed it is a black rectangle with a black piece extending down and to the right. There is a metalic fitting that engages the brushes. With nothing attached turn the motor on with the switch. If it doesn;t turn either the switch is bad or the motor is burned out. If you have a voltmeter check the ouyput side of the switch. If voltage is there check the motor plug. If good there the motor is bad. Hope this helps. Yes, the motor does get voltage when the switch is on. You can find parts by entering Hoover FloorMate H3000 parts into Google.

My name is rob, lets see if we can solve your problem
If the welders been working ok first question is what has changed, has it been moved or modified in any way?
Next, are ther any fuses or breakers fitted? are these ok?
Next, most engine driven welders have one major problem.
It shakes stuff loose, undos connections and damages static components,
Take some covers of to expose the internals and with THE ENGINE STOPPED check along the length of the cable harness especially at the ends of cables, give each terminal a tug with the cable to make sure there are no problems there. Also check the condition of the insulation of the harness along its lenght. at this point you may find a "hidden" in-line fuse somewhere in the harness if your lucky!
If none of this helps it gets a little more tricky, could you give me make and model? that would help a lot.

Remove front cover on the genset and you will see the brushes and rings. Clean the rings if black with emory cloth and inspect brushes. Flash the fields by apply a 12V battery to the brushes. the brush closest to you or the bearing is connected to the positive side of battery and the back brush is negative. You have to do this with genset running. You should notice your voltage climb up to over 50Vac maybe even over 100Vac. Make sure to use rubber gloves when flashing fields and keep hands away from rotating parts. if voltage does increase when flashing the the voltage regulator is shot. If voltage does not climb then you will need a new genset or generator end.
