Thanks, All. I expect I'll get the newest light bar on Monday or latest Tues (I only live 4 hours away from West Plains- HQ for Gammill) and I'm hopeful that will solve the problem. If not, my guess is the tech will be heading my way in the next few weeks. I can see well enough with my overhead lights to work off the back, or do easy E2E stuff (NOT on black!) but have 3 waiting for some custom work. I do have some stick-on LEDs but little worried it will throw the balance of the machine off some. I have posted on yahoo and Gammill forum, too. Just freaking that it might be wiring issue.
