How about either post here or send me an email and let me know where you are and what you have done, year of the machine, etc. I searched near Walnut Creek and I only have record of a few machines near you, none are the 1440E-LB, so need a few details. (Of course who knows where you got it, just trying to see what info I could find)
Best would be to post a picture of the electrical box and the contactor that you changed, and also how you have the motor wired now. The more details the better.
I have any info that you need for wiring, etc, but need some details where you are with it and what has been done so far.
It can be tough with used machines that someone messed around with before you got it, sometimes thats a headache, but we will get it figured out.
Email is much faster for me to reply,
sales@precisionmatthews.com or
matt@machinetoolonline.com
Or post here, others can also chime in.
