I am trying to wire a motor to go in reverse. It’s a lathe—and you will tease me, but it’s a harbor freight lathe. The 12 inch type, model 34706. This one: http://www.harborfreight.com/12-inch-x-33-3-8-eighth-inch-wood-lathe-with-reversible-head-34706.html#pr-header-back-to-top-link
I successfully wired my previous lathe to go in reverse when I flipped a “double-pole, double-throw switch.” It was a smaller Dayton motor and it had a nice wiring diagram on the motor housing. Easy as can be.
This HF motor is not so nice. There is no wiring diagram or information plate of any kind on the motor housing (not even to tell me how many amps it’s drawing, which I think is a safety concern. I emailed tech support but we’ll see if they even bother to email me back!)
But let me cut to the chase: when I switch the wires that I normally would to reverse direction, the motor continues to run forward. I have tried every combination, except swapping out the upper wires for the lower ones (I’m not that expeditious so far).
Anyone have an idea of what gives? The only info I have on the motor is that it is a capacitor start (the cap is bulging out of the top), and it’s the kind that has a switch or solenoid click on when it runs (I can hear the solenoid or whatever closing when the motor shuts off). The HF manual is, of course, not so helpful.
