How do I check the capacitors on my Warco Mill?

Bob, do you have any kind of starter with overload protection in the motor circuit ?
or are you controlling with a switch only ?

Hi Bob,
I think the fault needs to be looked at logically rather than just assuming the fault is with a capacitor on the motor. I have tried to find a schematic or manual on the web but the only thing I could find was a picture. Do you have a manual with a schematic in it ? If so can you post is copy of the schematic so we can suggest tests to localise the area of the fault.

Hi Les, I have looked for the manual for the mill but can't find it I'm pretty sure it has a wiring diagram wit it. The fuse blew as soon as I switched on the power and before I actually tried to start the spindle motor. I will see if I can find it.

Hello Bob,

The fault sounds like a dead short, either live to earth or live to neutral.

Les is quite right, it needs to be traced logically starting from just the wiring and working up as pieces of the circuit are added until it reveals itself. If it helps, the motor run windings should have a resistance of maybe 8 ohms, the starter winding roughly half that value.

Can you get a copy of the manual and/or the wiring diagram, it will help enormously.

Hi Brian,

I so far have been unable to trace a circuit diagram or instruction manual. First thing that comes to mind is to do some basic checking such as the plug and the control box to check for wires that may have become loosened be causing a short, beyond that I really don't know where to look.

I am fortunate that I have the CNC mill and it is easy to use, it's just nice to have a manual mill as a back up or spare in case I need to keep something on the CNC mill table.

If you can't find a schematic it will come down to tracing part or all of it. Some pictures of the control panel (The front as well as the inside as I could not read the labels on the buttons on the picture I found on the web.) the electrical control box on the back of the mill and the inside of the motor connection box would be a good place to start so we could talk you through tracing the wiring. Also is it plugged into a socket (16 amp ?) or hard wired to a connection box.

Les.
