race45 Posted March 19, 2013 Report Share Posted March 19, 2013 too bad you are not closer between John witche and myself we could have all the electrical and the electronics covered. Does it blow when you power up or when you are using? These can help you isolate you which components it is. Turn off power and open control cabinet and see or smell if something burned. That may not be the problem but may have burned becouse of the problem. Clare Link to comment Share on other sites More sharing options...
huff37 Posted March 19, 2013 Author Report Share Posted March 19, 2013 IT BLOWS as soon as I power up.the torque meter pointer slowly rotates round and round.have the cabinet open and do not see anything burned.the info plate on cabinet and frame(where the brake is both show 15amp 220 volt but looking at what little wiring diag. I have it seems to show both circuits tied together making it 110? I"m totally cornfused! Link to comment Share on other sites More sharing options...
race45 Posted March 20, 2013 Report Share Posted March 20, 2013 Not quite correct as one of my trainers would say. J J and S racing is an electrician and he can answer that. Are you sure it is wired correctly. Has it worked in that location before? Is this something new to you? no adding two 220 volt lines together does not make 110. Are you in a hurry to repair as I travel statewide alot? Â Clare Link to comment Share on other sites More sharing options...
race45 Posted March 20, 2013 Report Share Posted March 20, 2013 I just looked on line for information and found some. Can you provide any data on label plates such as date manufactured, who manufactured, model number etc. I am travelling to dallas area in the morning.

4cylfordz Posted March 20, 2013 Report Share Posted March 20, 2013 Please add pictures of the hook up and little diagram sounds allot like it may be a 110 unit . No legs off 220 should ever touch eachother as they are on different phases and will immediately arc. In us most supply's are 110v=110-N-G 220v=110-110-N till u get into 3phase Link to comment Share on other sites More sharing options...

huff37 Posted March 24, 2013 Author Report Share Posted March 24, 2013 yes 220v 15a and you may be right about rectifiers which I have no way to check.even if I had the test equipment I am not sure I would know how to use it.My electronics ability falls off sharply behind a test light Link to comment Share on other sites More sharing options...
