Hey guysI have a big 40 serial number: JJ521296 stock number: 903043. Its starts and runs great but when welding there is only a very faint spark when trying to strike. I have read alittle here and elsewhere about these machine and have seen just a few things to do or try but nothing to really let me know what Iam up against.First thing I did was clean the 3 rings (very dirty) and checked the brushes. Also to note I am getting power from the recepticle with grinder. I have checked for loose or burnt wires but nothing jumps out at me. I really need some advice on what Iam possible up against here and some guidance as I know nothing about these machines at all. Can someone please help me out here? Thanks and God Bless!!!
