And another drum switch question

I had to replace the drum switch that blew out on my LMS HT mill for the power feed w/fast travel & safety switch so it doesn't crash. What a mess. I had a wiring diagram with no colors, and all of the wires were black. I finally figured it out with an ohmmeter. I think when I assembled it, it ran in reverse of what I expected but I finally got it working correctly by swapping two wires. Good luck...

The picture of your motor plate states to switch the red and blue leads. In my pictures, the equivalent leads are T5 and J10.

My drum switch does turn off the motor in the central position.

MrDan commented the ground connection is on the lower left in my picture.

the directional control of the motor can be switched by the drum switch, but the issue is that you will need a secondary disconnect for the line connections

to wire for directional control:
disconnect the red wire at Motor Terminal 2, extend the wire and connect it to the Center Terminal of the Right Side for the Drum Switch
disconnect the black wire at Motor Terminal 5, extend the wire and connect it to the Center Terminal on the Left Side of the Drum Switch
connect a wire from the Top Right Drum Switch Terminal and extend it and connect it to Motor Terminal 2
connect a wire from the Bottom Left Drum Switch Terminal and extend it and connect it to Motor Terminal 5
this will complete directional control.

as far as wiring the secondary disconnect for the line connections, a simple 15a DPST toggle switch would suffice
the motor line connections are as follows:
Motor terminal 1= neutral (white)
Motor terminal 4= hot (Black)

for motor longevity,
i would recommend returning the drum switch to the center position and having the motor stop before switching the drum switch to the opposite direction

if you need clarification, i'm happy to assist in anyway i can

This should work without needing another switch

Sorry lets try this again: motor2a.jpg this should work and give center off.

1,2 and 4,5 are/were internally strapped in the motor I believe.

No luck..tried last two diagrams..magic smoke.redid wiring.took all apart.rewired thinking I screwed up. Smoke in 5 seconds..mark s diagram would do forward.reverse normal speed but the dreaded smoke in 5 seconds..can hook up black and red to terminals.runs.no smoke..reverse red .black.runs opposite..any ideas..thanks Phil
 
Ok understood- so there's some hocus pocus going on behind the terminal board. Looks like a second switch is the simplest option, like Ulma Doctor's sketch.

Mark.your diagram made forward.reverse work..but smoke and motor was warm real quick..terminal 2 where black wire is has a blue wire going down into motor.red wire is on terminal only. Thanks for your time
