I got it running. The problem turned out to be a bulb in the power start button I was waiting till I got it running to replace. I blew it well playing with the new transformer and looking over the diagrams it is part of the coil circuit. I don't know how I missed it before. Now just to order a...
The old transformer had a 6 volt out for bulbs. The new one only has 24 and 110 but I am not getting anwhere near those some are way high and come down with load. I think the line in and out are ok because if I hold the contactor buttons the motor runs but I can check if it will help.
I am getting about 7.5 to 8 ohms across a1 and a2 terminals on all 3 contactors. Fuse 1 I am getting 25 volts to both sides of the fuse. Fuse 2 I am only getting 3 volts to both sides. Ill try moveing it to a different spot on the transformer
I have that same schematic in my manual. The high voltage circuit seems fine I can hold in km1 then km2 and the motor runs forward or km1 and km3 and the motor runs in reverse. At this point if I hold push to start the km1 relay activates but the fwd rev switch will make the relay disengage. If...
Its single phase. I know A lot about dc electrical not so much about ac. By contractor I am talking about the relay not the switch. I have three relays on this machine. If I knew what each contact on these relays did I could figure it out. the bottom 2 appear to be the control side the center...
Yes I bought the lathe used it never has been the way it was designed. I used to have to hold the first contactor for a few seconds of every use then it would work normal. Then one day I plugged it in and the plug was arching. I unplugged it waited a minute or two tried again no arching but the...
I am having some issues with a older harbor freight lathe. And was wondering if any one has a better schematic then the one that comes in the book. I have checked grizzly but there's is wired totally different then mine.
i ended up buying the used 12x36 for 900 been doing alot of cleaning on it gotta change the head stock and apron oil and get to learning how to run it and make things
