Going off topic here a bit==I started working on the my tank today and one of our tech-guru's showed up and wanted to help get a machine going in the shop that will soon be going out the door.Think you can have a electrical problem on your tank,you should try working on these guys.My job for the last 15 years,lucky though when I have the shop at home and don't have to commute back and forth to work. A few pictures below,back on the tank tomorrow( I'm supposed to be retired,sure don't seem that way sometimes)

P.S. these are used machines and a lot of wires hanging all over the place,putting stuff in and taking stuff out so we can test run everything.Then I go back and reorginize everthing and make it look as neat as possible.
