Have an issue with a V200 drum. The drum operates fine except for the very left selection button. When selecting the far left button the motor for the drum spins very slow and does not extend all the way out to engage the clutch to move the drum is almost like the circuit for that selection has to much resistance in it. Some times it will chatter and then work. I replaced the far left arrow switch with an NOS one I had. I cleaned the two switches at the right side of the drum, I know the one is a motor switch. All other 4 arrow selections operate the motor very strongly. Any ideas, Thanks in advance.
