So I have had my 61 modular running great for almost exactly a year now and today it wouldn't start.
I had been using the taper attachment to make a dauber for Cal, and shut her off since I thought I would move operations back to the mill. Then realized a face of the part wasn't square and put it back in the lathe. Power on, wait 60, green light comes on, push Control On and there was no click. Motor won't start. Spindle lock not in, haven't touched that in months.
From a donie post
Power contactor will close when control on button is depressed but falls open when the control on button is released.
A. control off button is defective.
B. temperature switch is defective.
C. field loss relay is defective.
D. diodes in rec no. 3 defective.
E. c3j tube defective.
F. temperature switch open due to over heating of electronic unit- blower motor or dirty air filter.
My problem may not be the same as described here, because it appears that my power contactor will not close at all.
What is the click sound that my lathe has stopped making? Please be specific as to the location where I would direct my electrical cleaning spray.
So far I have
Replaced the C3J tube. I can't say that this C3J tube is working, bought it and 2 others on ebay last year and never tested them.
Replaced the original Module box. I bought one from everttengineer last year and repaired it. Have been using it since then and put my good working original away.
I guess I could try
the other two C3J tubes I have
F. Seems unlikely since I had been using the lathe for about an hour, and it is 40 degrees in my garage, if so, I suppose it would restart easily in the morning.
A. Control off button I'll check next
Does shorting lines 3-4 act as a substitute for a contactor failure? I read this elsewhere, if so, I would add a wire to 3 and a wire to 4 and route them out of the electrical panel, start the lathe, wait 60 for the light to come on, then connect them.
I also have a backup Field Failure Relay in my spare parts horde, I suppose that would be the field loss relay? I will try putting that one in.
I was just thinking that the lack of the click sound when pushing Control On pointed to something, just don't know what.
Thanks for reading this post, any help appreciated.
