I have a 1.6HP 33gallon Craftsman air compressor. It's one of the 120v oilless units, and the motor/pump/etc is basically all 1 unit under a large plastic shroud. This isn't one of the more robust units with a motor separate from a standalone pump.
It'll work well intermittently, and then at times will fire up for 1-3 seconds and shut right down. Try that a couple of times, and then it doesn't do anything at all for a while. I took off the shroud and noticed quite a bit of sparking from the brushes/armature area.
Any thoughts on what this could be? Brushes don't look to be crazily worn or anything. Is the motor just shot? Does this point to bad brushes, or something else bad internally to the motor?
If it is shot, any sort of quick and easy solution? I thought about buying a HF 2hp motor and pump and reusing the tank, gauge, regulator, etc...but that will still be well over $300. Budget is extremely tight at the moment.
