I have a older 90's ? Ernault Toyoda lathe with a 15t control. Just recently I have been gettin a no "control on chuck" alarm when i try to clamp on the O.D. of a bar. I can reverse the clamping direction and no alarm Until the pedal opens it again. I have also lost the close control on my foot pedal. voltage is at the pedal but no function. Any/All advise I can gather on this problem the better. Thank's
