Hello everyone and Happy New Year. I am newbie working on a Okuma LT-15. It is throwing an alarm code 1784 1 A on the upper turret. If you hold the button down it spins but when you you release it, turret stops and faults out. I am trying to locate the limit switches on this. I have taken a couple of the covers off but not really seeing anything yet. I am not a machinist, I am just trying to help out a buddy. Any help is greatly appreciated!! Thanks
