I managed to get a bike with this automatic electronic shifting system for a small fee. But does anyone know how it works? Nothing appears on the screen. Does the shifting system charge while riding?
(Excuses me for possibly using wrong terms, I used Google Translate).

Nexus Auto D from 1997.
Different control unit to your model, but I suspect operation will be similar

There is a lithium battery. Look at the diagram: [https://si.shimano.com/en/pdfs/ev/SE-4S35_AI-4S35_AI-4S41-1842/EV-SE-4S35_AI-4S35_AI-4S41-1842A.pdf](https://si.shimano.com/en/pdfs/ev/SE-4S35_AI-4S35_AI-4S41-1842/EV-SE-4S35_AI-4S35_AI-4S41-1842A.pdf)
But you’d need the charger, probably.
Look for Nexus Auto-D, for example this person had a similar issue: [https://www.radforum.de/threads/26102-shimano-nexus-auto-d-funktioniert-nicht](https://www.radforum.de/threads/26102-shimano-nexus-auto-d-funktioniert-nicht)
