TURNOVER INDICATOR IS STORED

The rotation indicator of my friends sometimes gets stuck at 0. It works smoothly the next day. It does not work again after a week. Is it a simple problem? Where should I look at it?

servo motor gears inside the indicator may have peeled off. Sometimes this type of problems can cause voltage imbalance.

Is it an expensive repair, Soner Bey?

They want around 200-300 TL, probably the parts are not expensive, but you know the industry, unfortunately, they are looking for a man to go.
