..Anyone here versed in the ways of neon???I had a troubleshooting job today, and,the sign has 16 letters,all individual, and powered by (3)15kv.,.30ma,120v. xfrmrs...The letters are mounted to the building exterior on VINYL SIDING..when I went to check them today,I didn't get nailed..lucky me..I was on a fiber-glass ladder,but I saw a small arc when I removed the letter lens..there was also alot of buzzing...The owners complaint is that at night, the 1st 6 letters are significantly darker than the rest...My question is this,should I ground these letters and replace the ballast, or ...??? Help!!!
