Who owns a Grizzly 4003 lathe from 1999 to 2005 ?

On other note the two left contact are wired through each other so if one is engaged (say reverse) and a call for forward (inching button or bad forward reverse switch) it wont allow the other to engage.

Can't I just disconnect the JOG button all together?
 
Left facing open switch with handle on top?

I am not talking about the contacts in your switch, I am talking about contactors in the electrical compartment on the back of the lathe
 
When you press power start do you hear the 3rd contactor close?

When you release the power start do you hear the 3rd contactor open?

no no.. If you hold the on button down and turn the lever on the drum switch. You hear them and the motor turns
 
if you touch black to blue and push power start what happens?

Warning that maybe 110v ac
 
The contractor on the top right with the yellow plunger is the one I believe you need to activate. BTW I gutted the box on mine and replaced with a VFD and a new 3 phase motor.
 
I think and I am only guessing by looking at manuals not for your year,

the 3rd contactor (with the yellow plunger) gets latched from the black and blue touching and you push the power start,

then with black and blue touching, and 3rd relay latched you choose direction by touching black and blue to either brown or red

Hope this helps..

I have to call it a night I will check back on progress in the AM
